記錄一下自動更新，自己寫的，流程非常之神奇和偷懶，有興趣的自己改寫成比較不偷懶的版本吧!!!

先介紹流程:

主Form在開啟時，呼叫WebApi確認是否有更新，有則啟動更新程式進行更新作業。

Main Form:

 1: public Form1()
 2: {
 3:     InitializeComponent();
 4:     //呼叫WebApi
 5:     CheckVersion();
 6:     //取得檔案本版編號
 7:     var version = FileVersionInfo.GetVersionInfo(Assembly.GetExecutingAssembly().Location).FileVersion;
 8:     this.Text += " v" + version; 
 9: }
 10:  
 11: private async void CheckVersion()
 12: {
 13:     #region WebApi Get
 14:     //此處利用.NetFramework 4.5 之非同步方法使用，系統最低OS規格為Vista以上(XP不能安裝4.5)，如要在XP使用請用傳統大腸包小腸寫法
 15:     var httpClient = new HttpClient();
 16:     var version = FileVersionInfo.GetVersionInfo(Assembly.GetExecutingAssembly().Location).FileVersion;
 17:     var address = new Uri("http://localhost:52666/api/OutlookApi/" + version);
 18:     HttpResponseMessage response = await httpClient.GetAsync(address);
 19:     response.EnsureSuccessStatusCode();
 20:     var _path = await response.Content.ReadAsStringAsync();
 21:     #endregion
 22:     string exeFile = (new System.Uri(Assembly.GetEntryAssembly().CodeBase)).AbsolutePath;
 23:     string exeDir = Path.GetDirectoryName(exeFile);
 24:     string fullPath = exeDir + "\\Update.zip";
 25:     if (!string.IsNullOrEmpty(_path))
 26:     {
 27:         using (WebClient webClient = new WebClient())
 28:         {
 29:             try
 30:             {
 31:                 webClient.DownloadFile(_path.Replace("\"", ""), fullPath);
 32:                 MessageBox.Show("有新版本，請點選確定開始更新!!");
 33:                 Process p = Process.Start("OutlookUpdate.exe");
 34:                 this.Close();
 35:             }
 36:             catch
 37:             {
 38:                 File.Delete(fullPath);
 39:             }
 40:         }
 41:     }
 42: }

 

Web Api:

 1: public class OutlookApiController : ApiController
 2: {
 3:     // GET api/OutlookApi/5
 4:     public string Get(string id)
 5:     {
 6:         if (id == FileVersionInfo.GetVersionInfo(Assembly.GetExecutingAssembly().Location).FileVersion)
 7:             return "";
 8:         else
 9:         {
 10:             //回傳更新檔所在位置
 11:             return "http://localhost:52666/updatedata/Export_test.zip";
 12:         }
 13:     }
 14: }

 

Update Form:

 1: using MySharpZip;
 2:  
 3: public UpdateForm()
 4: {
 5:     InitializeComponent();
 6:     update();
 7: }
 8:  
 9: private void update()
 10: {
 11:     string exeFile = (new System.Uri(Assembly.GetEntryAssembly().CodeBase)).AbsolutePath;
 12:     string exeDir = Path.GetDirectoryName(exeFile);
 13:     string fullPath = exeDir + "\\Update.zip";
 14:  
 15:     if (File.Exists(fullPath))
 16:     {
 17:         //用第三方套件提供解壓縮功能
 18:         CZip oZip = new CZip();
 19:         oZip.UnZipFile(fullPath, exeDir);
 20:         MessageBox.Show("更新成功!!");
 21:     }
 22:     else
 23:     {
 24:         MessageBox.Show("不需更新!!");
 25:     }
 26:  
 27:     Process p = Process.Start("OutlookImport.exe");
 28:     this.Close();
 29: }

可以看到我因為偷懶，所以使用API端的檔案版本跟WinForm端的檔案版本直接做比對，此方法有缺點，所以建議把WinForm端的版本編號存至資料庫或是設定檔裡面會比較好一些。
