# C# 實現客戶端程序自動更新

看到一篇不錯的帖子，可能以后會用到，果斷收藏

由于微軟提供的更新程序使用不方便,所以又寫了此程序。此程序是本人一年前所寫的一段程序,當時在開發一個CS版本報價系統,當時由于開發過程倉促,代碼可能有點不是太規范此程序編譯后只有一下AutoUpdate.exe文件與一個配置文件UpdateList.xml，主要通過本地程序與服務端程序文件的版本號來升級與更新本地程序文件。

UpdateList.xml文件內容如下：

<?xml version="1.0" encoding="gb2312"?><AutoUpdater>

`<description>`Application autoUpdate `</description>`
`<Updater>`
`<Url>`http://10.0.5.98/SoftUpdate/`</Url>`
`<LastUpdateTime>`2005-09-05 `</LastUpdateTime>`
`</Updater>`
`<Application applicationId="ItemSoft">`
`<EntryPoint>`ItemSoft.exe `</EntryPoint>`
`<Location>`.`</Location>`
`<Version>`1.0.0.0 `</Version>`
`</Application>`
`<Files>`
`<File Ver="1.0.0.0" Name="ItemSoft.exe" />`
`<File Ver="1.0.0.0" Name="Reports\test.txt"/>`
`<File Ver="1.0.0.0" Name="Interop.grproLib.dll"/>`
`<File Ver="1.0.0.0" Name="Reports\test.grf"/>`
`</Files>`
`</AutoUpdater>`

說明：
`<description></description>`     程序的描述；
`<Url></Url>`                            更新服務器地址，為一個虛擬目錄或站點路徑；
`<EntryPoint></EntryPoint>`      需要更新主程序文件，為exe；
`<Location>`.`</Location>`         需要更新主程序文件所在路徑；
`<Version>`1.0.0.0 `</Version>`   主程序版本號；
`<Files>` `</Files>`                     需要更新的文件列表；Ver：文件版本號，Name：文件名，包括路徑(相對);

使用時，在更新服務器上新建Web虛擬目錄或站點，然后將需要更新的文件與UpdateList.xml放在上面；
本地將AutoUpdate.exe與UpdateList.xml放在主程序的根目錄下。本地UpdateList.xml中的版本號如果小于服務端，自動程序會自動下載所需要更新的文件。
本人的完整.Net打包程序下載中所帶的項目中，就使用了此更新程序。

# [c#自動更新程序](https://www.cnblogs.com/keguoquan/p/14542631.html)

**主要功能介紹**

實現文件的自動更新。主要功能：

1. 支持整包完全更新，即客戶端只需輸入一個服務器地址，即可下載所有文件。
2. 支持增量更新，即只更新指定的某幾個文件。
3. 支持自動更新程序的更新

更新界面如圖：

服務端

服務端主Xml版本文件，包含所有的項目文件，客戶端根據每個文件的版本號進行判斷是否需要更新。如果需只更新某幾個文件，則將對應文件的版本號更改只更高的版本號即可

# [C# Winform 自動更新程序實例](https://www.cnblogs.com/garychk/p/7978710.html)

第一步：檢查更新

檢查更新其實無非就是去比較更新包的版本和本地軟件版本，如果高則更新、低則不更新。怎么獲取版本號方法很多，本案例是獲取軟件的配置文件。

[![復制代碼](http://www.matrixbk.com/usr/uploads/2023/01/80370365.gif)](javascript:void(0); "復制代碼")

```
private bool CheckUpdate()
        {
            bool result = false;
            try
            {
                string Cfg = TxtRead(exePath   "\\Config.txt");
                ConfigLocal = JsonConvert.DeserializeObject<DTO_Config>(Cfg);
 
                CheckUpdateURL = ConfigLocal.AutoUpdateURL;
 
                Cfg = TxtRead(CheckUpdateURL   "\\Config.txt");
                ConfigRemote = JsonConvert.DeserializeObject<DTO_Config>(Cfg);              
 
                VersionR = ConfigRemote.Version;
                VersionL = ConfigLocal.Version;
                int VersionRemote = int.Parse(ConfigRemote.Version.Replace(".", ""));
                int VersionLocal = int.Parse(ConfigLocal.Version.Replace(".", ""));
 
                result = VersionRemote > VersionLocal;
            }
            catch { }
            return result;
        }
```

第二步：下載更新包

因為C/S的軟件更新是面對所有用戶，S端除了給C端提供基本的服務外，還可以給C端提供更新包。而這個S端可以是網絡上的一個固定地址，也可以是局域網內一個公共盤。那下載更新包無非就是去訪問服務端的文件，然后Copy下來或下載下來。下面給出訪問網絡和訪問局域網兩個案例：

A、訪問遠程網絡地址這里采用的是WebClient

[![復制代碼](http://www.matrixbk.com/usr/uploads/2023/01/1291920084.gif)](javascript:void(0); "復制代碼")

```
public void DownLoadFile()
        {
            if (!Directory.Exists(UpdateFiles))
            {
                Directory.CreateDirectory(UpdateFiles);
            }
            using (WebClient webClient = new WebClient())
            {
                try
                {
                    webClient.DownloadFileCompleted  = new AsyncCompletedEventHandler(client_DownloadFileCompleted);
                    webClient.DownloadProgressChanged  = new DownloadProgressChangedEventHandler(client_DownloadProgressChanged);
                    webClient.DownloadFileAsync(new Uri(CheckUpdateURL   "\\UpdateFile.rar"), UpdateFiles   "\\UpdateFile.rar");
                }
                catch (WebException ex)
                {
                    MessageBox.Show(ex.Message, "系統提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
                }
            }
        }
```

[![復制代碼](http://www.matrixbk.com/usr/uploads/2023/01/1259096145.gif)](javascript:void(0); "復制代碼")

這里面應用到兩個方法，DownloadProgressChanged，監聽異步下載的進度；DownloadFileCompleted，監聽完成異步文件下載；

[![復制代碼](http://www.matrixbk.com/usr/uploads/2023/01/6276885.gif)](javascript:void(0); "復制代碼")

```
private void client_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
        {
            this.progressBarUpdate.Minimum = 0;
            this.progressBarUpdate.Maximum = (int)e.TotalBytesToReceive;
            this.progressBarUpdate.Value = (int)e.BytesReceived;
            this.lblPercent.Text = e.ProgressPercentage   "%";
        }
```

[![復制代碼](http://www.matrixbk.com/usr/uploads/2023/01/3550395592.gif)](javascript:void(0); "復制代碼")

```
private void client_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e)
        {
            if (e.Error != null)
            {
                MessageBox.Show(e.Error.Message, "系統提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
            else
            {
                this.lblMessage.Text = "下載完成";
                //復制更新文件替換舊文件
                DirectoryInfo TheFolder = new DirectoryInfo(UpdateFiles);
                foreach (FileInfo NextFile in TheFolder.GetFiles())
                {
                    File.Copy(NextFile.FullName, Application.StartupPath   NextFile.Name, true);
                }
              
            }
        }
```

[![復制代碼](http://www.matrixbk.com/usr/uploads/2023/01/1868787972.gif)](javascript:void(0); "復制代碼")

B、訪問服務端公共盤，直接采用File.Copy

[![復制代碼](http://www.matrixbk.com/usr/uploads/2023/01/3200825537.gif)](javascript:void(0); "復制代碼")

```
public void GetRemoteFile()
        {
            try
            {
                DirectoryInfo TheFolder = new DirectoryInfo(CheckUpdateURL);
                FileInfo[] FileList = TheFolder.GetFiles();
                this.progressBarUpdate.Minimum = 0;
                this.progressBarUpdate.Maximum = FileList.Length;
 
                foreach (FileInfo NextFile in FileList)
                {
                    if (NextFile.Name != "Config.txt")
                    {
                        File.Copy(NextFile.FullName, exePath   "\\"   NextFile.Name, true);                      
                    }
                    this.lblMessage.Text = "更新"   NextFile.Name;
                    this.progressBarUpdate.Value  = 1;
                    this.lblPercent.Text = "更新進度... "   (this.progressBarUpdate.Value / FileList.Length) * 100   "%";
                }
                this.lblMessage.Text = "更新完成";
                //更改本地版本號為最新版本號
                ConfigLocal.Version = VersionR;
                string cfgs = JsonConvert.SerializeObject(ConfigLocal);
                TxtWrite(Application.StartupPath   "\\Config.txt", cfgs);
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message, "系統提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
        }
```

第三步：替換本地文件

這一步或許在第二步中已經實現了，如果你采用的是File.Copy。替換也就是復制粘貼的問題。采用WebClient下載了zip包，那還需解壓一下壓縮包然后再File.Copy。

# [C#實現之(自動更新)](https://www.cnblogs.com/yelanggu/p/9288149.html)

做開發的人，尤其是做客戶端(C/S)系統開發的人都會遇到一個頭疼的問題，就是軟件的自動更新；系統發布后怎樣自動的更新程序，在下有幸開發過一個自動更新程序，更新程序與任何宿主程序是完全獨立的；只要在主程序里面啟動更新程序就行了；更新程序也是一個可執行文件，在啟動的時候可以設置是否是自動更新和是否是手動更新，自動更新的意思就是說不需要人工的干預實現從遠程服務器下載更新包，而如果是手動更新就會涉及到用戶點擊程序中的按鈕實現更新；在自動更新與手動更新中可以根據項目的需要進行選擇，有的程序必須要求用戶進行更新才能繼續使用，所以程序自動更新是有必要的；手動更新就是用戶可以隨時更新程序，不需要嚴格的控制版本問題；下面本人就來講一下具體的實現細節，我貼出部分代碼，源碼屬公司財產本人不宜上傳；

自動更新的目的就是將服務器上的DLL文件拷貝到本地執行目錄中，并且覆蓋本地同名的文件；流程很簡單，但是實現起來有幾個地方需要注意：

1.大批量的DLL文件怎么下載到本地來，有多個DLL文件在下載過程中如果網速慢的情況下可能出現丟包、丟文件等情況；本人的實現是將多個文件通過ICSharpCode.SharpZipLib組件進行打包，這樣可以省很多事；(如：動態連接庫文件dll的名稱在傳輸過程中大小寫可能會變化)

2.下載到本地了，怎么覆蓋原有的同名文件；本人的實現是先同名的文件的支持刪除，然后解壓縮；這個過程需要臨時保存刪除的文件，防止操作失敗程序無法啟動，要注意有事務性的原理；

3.如果更新的文件不只是單單的DLL文件可能還有一些無限極的文件夾；本人的實現是如果存在同名的文件夾，直接遞歸的刪除，然后將其解壓縮到目錄中；由于壓縮包解壓后的頂級目錄是壓縮文件的名稱，所有在復制的過程中需要注意目錄的層次關系；

下面我們來走一下實現的整個流程，雖然沒有給出整個源碼，但是如果看完這篇文章的你基本實現起來沒什么大問題了；

為了部署方便我建議大家麻煩點實現一個部署文件的工具，將所有的文件直接打包在里面同時生成服務器端的版本信息文件；

利用這個工具就很方便的實現了對文件進行壓縮、生成HASH值、版本文件、更新地址等信息；

![](http://www.matrixbk.com/usr/uploads/2023/01/2147983684.png)

這個XML中保存的是服務當前的版本信息、更新文件的名稱、更新文件的HASH值，為什么需要HASH就是怕更新文件在某些情況下被人調包了，如果所有的客戶端更新后后果很嚴重；所以我們必須帶上HASH值；

![](http://www.matrixbk.com/usr/uploads/2023/01/3562512474.png)![](http://www.matrixbk.com/usr/uploads/2023/01/1818084326.png)

工具生成兩個文件，一個是版本文件一個是更新包，服務器的任務已經完成，下面就是具體的客戶端的實現；

為了知道何時需要進行版本更新所以要在客戶端程序目錄中保存一份用來記錄版本信息的文件；

![](http://www.matrixbk.com/usr/uploads/2023/01/3776245193.png)

文件中保存著當前本地的版本號、服務器的更新地址、宿主程序的名稱，需要宿主的名稱就能在更新的時候將宿主程序重進程中枚舉出來然后關掉，這樣就不影響我們更新了，當然也可以實現宿主程序不關閉的情況下更新，如果用到某些已經被宿主程序占用的情況會直接影響更新流程，所以以防萬一關了為妙；

![](http://www.matrixbk.com/usr/uploads/2023/01/932237002.png)

這是客戶端版本文件中保存的信息；

我們上面說了，更新分為手動和自動，我們先來說手動更新吧，手動更新就是需要用戶自己去點擊更新按鈕然后開始更新，這個問題我們可以利用進程的參數傳遞解決；

![](http://www.matrixbk.com/usr/uploads/2023/01/570326461.png)

當然在更新程序里面需要有這方面的邏輯判斷；

![](http://www.matrixbk.com/usr/uploads/2023/01/2580450883.png)

入口的地方我們進行判斷，更新方式；這里的下載遠程更新包是用WebClient對象，也可以用其他的基于Socket的對象；更新開始之前需要先判斷本地的版本號是否小于遠程版本號，如果小于在進行更新；

![](http://www.matrixbk.com/usr/uploads/2023/01/3076232122.png)

因為下載的過程是異步的所以需要用到后臺線程建議大家使用System.ComponentModel.BackgroundWorker這個后臺線程對象，他對Thread進行了很好的封裝；下面來看一下核心的流程代碼：

# C# 實現客戶端程序自動更新

看到一篇不錯的帖子，可能以后會用到，果斷收藏

文章來源 博客園 jenry（云飛揚）http://www.cnblogs.com/jenry/archive/2006/08/15/477302.html

由于微軟提供的更新程序使用不方便,所以又寫了此程序。此程序是本人一年前所寫的一段程序,當時在開發一個CS版本報價系統,當時由于開發過程倉促,代碼可能有點不是太規范此程序編譯后只有一下AutoUpdate.exe文件與一個配置文件UpdateList.xml，主要通過本地程序與服務端程序文件的版本號來升級與更新本地程序文件。

![image.png](http://www.matrixbk.com/usr/uploads/2023/01/3672043694.png)

![image.png](http://www.matrixbk.com/usr/uploads/2023/01/642699071.png)

UpdateList.xml文件內容如下：

<?xml version="1.0" encoding="gb2312"?><AutoUpdater>

`<description>`Application autoUpdate `</description>`
`<Updater>`
`<Url>`http://10.0.5.98/SoftUpdate/`</Url>`
`<LastUpdateTime>`2005-09-05 `</LastUpdateTime>`
`</Updater>`
`<Application applicationId="ItemSoft">`
`<EntryPoint>`ItemSoft.exe `</EntryPoint>`
`<Location>`.`</Location>`
`<Version>`1.0.0.0 `</Version>`
`</Application>`
`<Files>`
`<File Ver="1.0.0.0" Name="ItemSoft.exe" />`
`<File Ver="1.0.0.0" Name="Reports\test.txt"/>`
`<File Ver="1.0.0.0" Name="Interop.grproLib.dll"/>`
`<File Ver="1.0.0.0" Name="Reports\test.grf"/>`
`</Files>`
`</AutoUpdater>`

說明：
`<description></description>`     程序的描述；
`<Url></Url>`                            更新服務器地址，為一個虛擬目錄或站點路徑；
`<EntryPoint></EntryPoint>`      需要更新主程序文件，為exe；
`<Location>`.`</Location>`         需要更新主程序文件所在路徑；
`<Version>`1.0.0.0 `</Version>`   主程序版本號；
`<Files>` `</Files>`                     需要更新的文件列表；Ver：文件版本號，Name：文件名，包括路徑(相對);

使用時，在更新服務器上新建Web虛擬目錄或站點，然后將需要更新的文件與UpdateList.xml放在上面；
本地將AutoUpdate.exe與UpdateList.xml放在主程序的根目錄下。本地UpdateList.xml中的版本號如果小于服務端，自動程序會自動下載所需要更新的文件。
本人的完整.Net打包程序下載中所帶的項目中，就使用了此更新程序。

# [c#自動更新程序](https://www.cnblogs.com/keguoquan/p/14542631.html)

**主要功能介紹**

實現文件的自動更新。主要功能：

1. 支持整包完全更新，即客戶端只需輸入一個服務器地址，即可下載所有文件。
2. 支持增量更新，即只更新指定的某幾個文件。
3. 支持自動更新程序的更新

更新界面如圖：

服務端

服務端主Xml版本文件，包含所有的項目文件，客戶端根據每個文件的版本號進行判斷是否需要更新。如果需只更新某幾個文件，則將對應文件的版本號更改只更高的版本號即可

# [C# Winform 自動更新程序實例](https://www.cnblogs.com/garychk/p/7978710.html)

第一步：檢查更新

檢查更新其實無非就是去比較更新包的版本和本地軟件版本，如果高則更新、低則不更新。怎么獲取版本號方法很多，本案例是獲取軟件的配置文件。

[![復制代碼](http://www.matrixbk.com/usr/uploads/2023/01/80370365.gif)](javascript:void(0); "復制代碼")

```
private bool CheckUpdate()
        {
            bool result = false;
            try
            {
                string Cfg = TxtRead(exePath   "\\Config.txt");
                ConfigLocal = JsonConvert.DeserializeObject<DTO_Config>(Cfg);
 
                CheckUpdateURL = ConfigLocal.AutoUpdateURL;
 
                Cfg = TxtRead(CheckUpdateURL   "\\Config.txt");
                ConfigRemote = JsonConvert.DeserializeObject<DTO_Config>(Cfg);              
 
                VersionR = ConfigRemote.Version;
                VersionL = ConfigLocal.Version;
                int VersionRemote = int.Parse(ConfigRemote.Version.Replace(".", ""));
                int VersionLocal = int.Parse(ConfigLocal.Version.Replace(".", ""));
 
                result = VersionRemote > VersionLocal;
            }
            catch { }
            return result;
        }
```

第二步：下載更新包

因為C/S的軟件更新是面對所有用戶，S端除了給C端提供基本的服務外，還可以給C端提供更新包。而這個S端可以是網絡上的一個固定地址，也可以是局域網內一個公共盤。那下載更新包無非就是去訪問服務端的文件，然后Copy下來或下載下來。下面給出訪問網絡和訪問局域網兩個案例：

A、訪問遠程網絡地址這里采用的是WebClient

[![復制代碼](http://www.matrixbk.com/usr/uploads/2023/01/1291920084.gif)](javascript:void(0); "復制代碼")

```
public void DownLoadFile()
        {
            if (!Directory.Exists(UpdateFiles))
            {
                Directory.CreateDirectory(UpdateFiles);
            }
            using (WebClient webClient = new WebClient())
            {
                try
                {
                    webClient.DownloadFileCompleted  = new AsyncCompletedEventHandler(client_DownloadFileCompleted);
                    webClient.DownloadProgressChanged  = new DownloadProgressChangedEventHandler(client_DownloadProgressChanged);
                    webClient.DownloadFileAsync(new Uri(CheckUpdateURL   "\\UpdateFile.rar"), UpdateFiles   "\\UpdateFile.rar");
                }
                catch (WebException ex)
                {
                    MessageBox.Show(ex.Message, "系統提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
                }
            }

這里面應用到兩個方法，DownloadProgressChanged，監聽異步下載的進度；DownloadFileCompleted，監聽完成異步文件下載；

B、訪問服務端公共盤，直接采用File.Copy

[![復制代碼](http://www.matrixbk.com/usr/uploads/2023/01/3200825537.gif)](javascript:void(0); "復制代碼")

```
public void GetRemoteFile()
        {
            try
            {
                DirectoryInfo TheFolder = new DirectoryInfo(CheckUpdateURL);
                FileInfo[] FileList = TheFolder.GetFiles();
                this.progressBarUpdate.Minimum = 0;
                this.progressBarUpdate.Maximum = FileList.Length;
 
                foreach (FileInfo NextFile in FileList)
                {
                    if (NextFile.Name != "Config.txt")
                    {
                        File.Copy(NextFile.FullName, exePath   "\\"   NextFile.Name, true);                      
                    }
                    this.lblMessage.Text = "更新"   NextFile.Name;
                    this.progressBarUpdate.Value  = 1;
                    this.lblPercent.Text = "更新進度... "   (this.progressBarUpdate.Value / FileList.Length) * 100   "%";
                }
                this.lblMessage.Text = "更新完成";
                //更改本地版本號為最新版本號
                ConfigLocal.Version = VersionR;
                string cfgs = JsonConvert.SerializeObject(ConfigLocal);
                TxtWrite(Application.StartupPath   "\\Config.txt", cfgs);
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message, "系統提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
        }
```

第三步：替換本地文件

這一步或許在第二步中已經實現了，如果你采用的是File.Copy。替換也就是復制粘貼的問題。采用WebClient下載了zip包，那還需解壓一下壓縮包然后再File.Copy。

# [C#實現之(自動更新)](https://www.cnblogs.com/yelanggu/p/9288149.html)

做開發的人，尤其是做客戶端(C/S)系統開發的人都會遇到一個頭疼的問題，就是軟件的自動更新；系統發布后怎樣自動的更新程序，在下有幸開發過一個自動更新程序，更新程序與任何宿主程序是完全獨立的；只要在主程序里面啟動更新程序就行了；更新程序也是一個可執行文件，在啟動的時候可以設置是否是自動更新和是否是手動更新，自動更新的意思就是說不需要人工的干預實現從遠程服務器下載更新包，而如果是手動更新就會涉及到用戶點擊程序中的按鈕實現更新；在自動更新與手動更新中可以根據項目的需要進行選擇，有的程序必須要求用戶進行更新才能繼續使用，所以程序自動更新是有必要的；手動更新就是用戶可以隨時更新程序，不需要嚴格的控制版本問題；下面本人就來講一下具體的實現細節，我貼出部分代碼，源碼屬公司財產本人不宜上傳；

自動更新的目的就是將服務器上的DLL文件拷貝到本地執行目錄中，并且覆蓋本地同名的文件；流程很簡單，但是實現起來有幾個地方需要注意：

1.大批量的DLL文件怎么下載到本地來，有多個DLL文件在下載過程中如果網速慢的情況下可能出現丟包、丟文件等情況；本人的實現是將多個文件通過ICSharpCode.SharpZipLib組件進行打包，這樣可以省很多事；(如：動態連接庫文件dll的名稱在傳輸過程中大小寫可能會變化)

2.下載到本地了，怎么覆蓋原有的同名文件；本人的實現是先同名的文件的支持刪除，然后解壓縮；這個過程需要臨時保存刪除的文件，防止操作失敗程序無法啟動，要注意有事務性的原理；

3.如果更新的文件不只是單單的DLL文件可能還有一些無限極的文件夾；本人的實現是如果存在同名的文件夾，直接遞歸的刪除，然后將其解壓縮到目錄中；由于壓縮包解壓后的頂級目錄是壓縮文件的名稱，所有在復制的過程中需要注意目錄的層次關系；

下面我們來走一下實現的整個流程，雖然沒有給出整個源碼，但是如果看完這篇文章的你基本實現起來沒什么大問題了；

為了部署方便我建議大家麻煩點實現一個部署文件的工具，將所有的文件直接打包在里面同時生成服務器端的版本信息文件；

![](http://www.matrixbk.com/usr/uploads/2023/01/1357598868.png)

利用這個工具就很方便的實現了對文件進行壓縮、生成HASH值、版本文件、更新地址等信息；

![](http://www.matrixbk.com/usr/uploads/2023/01/2147983684.png)

這個XML中保存的是服務當前的版本信息、更新文件的名稱、更新文件的HASH值，為什么需要HASH就是怕更新文件在某些情況下被人調包了，如果所有的客戶端更新后后果很嚴重；所以我們必須帶上HASH值；

![](http://www.matrixbk.com/usr/uploads/2023/01/3562512474.png)![](http://www.matrixbk.com/usr/uploads/2023/01/1818084326.png)

工具生成兩個文件，一個是版本文件一個是更新包，服務器的任務已經完成，下面就是具體的客戶端的實現；

為了知道何時需要進行版本更新所以要在客戶端程序目錄中保存一份用來記錄版本信息的文件；

![](http://www.matrixbk.com/usr/uploads/2023/01/3776245193.png)

文件中保存著當前本地的版本號、服務器的更新地址、宿主程序的名稱，需要宿主的名稱就能在更新的時候將宿主程序重進程中枚舉出來然后關掉，這樣就不影響我們更新了，當然也可以實現宿主程序不關閉的情況下更新，如果用到某些已經被宿主程序占用的情況會直接影響更新流程，所以以防萬一關了為妙；

![](http://www.matrixbk.com/usr/uploads/2023/01/932237002.png)

這是客戶端版本文件中保存的信息；

我們上面說了，更新分為手動和自動，我們先來說手動更新吧，手動更新就是需要用戶自己去點擊更新按鈕然后開始更新，這個問題我們可以利用進程的參數傳遞解決；

![](http://www.matrixbk.com/usr/uploads/2023/01/570326461.png)

當然在更新程序里面需要有這方面的邏輯判斷；

![](http://www.matrixbk.com/usr/uploads/2023/01/2580450883.png)

入口的地方我們進行判斷，更新方式；這里的下載遠程更新包是用WebClient對象，也可以用其他的基于Socket的對象；更新開始之前需要先判斷本地的版本號是否小于遠程版本號，如果小于在進行更新；

![](http://www.matrixbk.com/usr/uploads/2023/01/3076232122.png)

因為下載的過程是異步的所以需要用到后臺線程建議大家使用System.ComponentModel.BackgroundWorker這個后臺線程對象，他對Thread進行了很好的封裝；下面來看一下核心的流程代碼：
