五、AutoUpdaterTest
5.1、實體類
作用：本地配置AutoUpdateConfig.xml檔案的序列化及反序列化實體物件。
public class AutoUpdateConfig { /// <summary> /// 自動升級模式：當前僅支援HTTP /// </summary> public string AutoUpdateMode { get; set; } /// <summary> /// HTTP自動升級模式時的URL地址 /// </summary> public string AutoUpdateHttpUrl { get; set; } }AutoUpdateConfig.cs
5.2、通用類
作用：應用程式全域性靜態常量。全域性引數都在此設定，方便統一管理。注：客戶端是否檢測更新，也是在此設定預設值。
/// <summary> /// 應用程式全域性靜態常量 /// </summary> public static class GlobalParam { #region 自動更新引數 /// <summary> /// 是否檢查自動更新：預設是true /// </summary> public static string CheckAutoUpdate = "true"; /// <summary> /// 本地自動更新配置XML檔名 /// </summary> public const string AutoUpdateConfig_XmlFileName = "AutoUpdateConfig.xml"; /// <summary> /// 本地自動更新下載臨時存放目錄 /// </summary> public const string TempDir = "Temp"; /// <summary> /// 遠端自動更新資訊XML檔名 /// </summary> public const string AutoUpdateInfo_XmlFileName = "AutoUpdateInfo.xml"; /// <summary> /// 遠端自動更新檔案存放目錄 /// </summary> public const string RemoteDir = "AutoUpdateFiles"; /// <summary> /// 主執行緒名 /// </summary> public const string MainProcess = "AutoUpdaterTest"; #endregion }GlobalParam.cs
作用：應用程式上下文。
/// <summary> /// 應用程式上下文 /// </summary> public class AppContext { /// <summary> /// 客戶端配置檔案 /// </summary> public static AutoUpdateConfig AutoUpdateConfigData { get; set; } }AppContext.cs
作用：應用程式配置。
public class AppConfig { private static readonly object _lock = new object(); private static AppConfig _instance = null; #region 自動更新配置 /// <summary> /// 自動更新配置資料 /// </summary> public AutoUpdateConfig AutoUpdateConfigData { get; set; } private AppConfig() { AutoUpdateConfigData = new AutoUpdateConfig(); } public static AppConfig Instance { get { if (_instance == null) { lock (_lock) { if (_instance == null) { _instance = new AppConfig(); } } } return _instance; } } /// <summary> /// 本地自動更新下載臨時資料夾路徑 /// </summary> public string TempPath { get { return string.Format("{0}\\{1}", Application.StartupPath, GlobalParam.TempDir); } } /// <summary> /// 初始化系統配置資訊 /// </summary> public void InitialSystemConfig() { AutoUpdateConfigData.AutoUpdateMode = AppContext.AutoUpdateConfigData.AutoUpdateMode; AutoUpdateConfigData.AutoUpdateHttpUrl = AppContext.AutoUpdateConfigData.AutoUpdateHttpUrl; } #endregion }AppConfig.cs
5.3、本地配置檔案
作用：配置自動更新模式及相關。
注1：複製到輸出目錄選擇始終複製。
注2：主程式執行時，先讀取此配置更新檔案，然後給AppContext上下文賦值，接著給AppConfig配置賦值。
<?xml version="1.0" encoding="utf-8" ?> <AutoUpdateConfig> <!--自動升級模式：當前僅支援HTTP--> <AutoUpdateMode>HTTP</AutoUpdateMode> <!--HTTP自動升級模式時的URL地址--> <AutoUpdateHttpUrl>http://127.0.0.1:6600/AutoUpdateDir</AutoUpdateHttpUrl> </AutoUpdateConfig>AutoUpdateConfig.xml
5.4、主程式
新建一個Windows窗體MainForm，此處理僅需要一個空白窗體即可，作測試用。
public partial class MainForm : Form { private static MainForm _Instance; /// <summary> /// MainForm主窗體例項 /// </summary> public static MainForm Instance { get { if (_Instance == null) { _Instance = new MainForm(); } return _Instance; } } public MainForm() { InitializeComponent(); } }MainForm.cs
5.5、應用程式主入口點
作用：檢測應用程式是否需要自動更新，如裡需要則檢測遠端服務端的版本號。假如遠端服務端有新版本，則呼叫自動更新器AutoUpdater並向其傳遞4個引數。
internal static class Program { /// <summary> /// 應用程式的主入口點 /// </summary> [STAThread] private static void Main(string[] args) { //嘗試設定訪問許可權 FileUtility.AddSecurityControll2Folder("Users", Application.StartupPath); //未捕獲的異常處理 Application.ThreadException += Application_ThreadException; Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException); AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException; //是否檢查自動更新賦值 if (args.Length > 0) { GlobalParam.CheckAutoUpdate = args[0]; } //載入自動更新配置檔案，給上下文AppServiceConfig物件賦值。 var config = AutoUpdateHelper.Load(); AppContext.AutoUpdateConfigData = config; //窗體互斥體 var instance = new Mutex(true, GlobalParam.MainProcess, out bool isNewInstance); if (isNewInstance == true) { if (GlobalParam.CheckAutoUpdate.ToBoolean()) { if (CheckUpdater()) ProcessUtility.KillProcess(GlobalParam.MainProcess); } Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(MainForm.Instance); instance.ReleaseMutex(); } else { MessageBox.Show("已經啟動了一個程式，請先退出。", "提示", MessageBoxButtons.OK, MessageBoxIcon.Error); Application.Exit(); } } /// <summary> /// 自動更新檢測 /// </summary> /// <returns></returns> private static bool CheckUpdater() { if (GlobalParam.CheckAutoUpdate.ToBoolean() == false) return false; #region 檢查版本更新 Stopwatch stopwatch = new Stopwatch(); stopwatch.Start(); bool blFinish = false; AppConfig.Instance.InitialSystemConfig(); var helper = new AutoUpdateHelper(AppConfig.Instance.AutoUpdateConfigData.AutoUpdateMode); string fileVersion = FileVersionInfo.GetVersionInfo(Application.ExecutablePath).FileVersion; long localVersion = 0; long remoteVersion = 0; try { localVersion = fileVersion.Replace(".", "").ToLong(); remoteVersion = helper.GetRemoteAutoUpdateInfoVersion().Replace(".", "").ToLong(); if ((localVersion > 0) && (localVersion < remoteVersion)) { blFinish = true; string autoUpdateConfigXmlPath = helper.WriteLocalAutoUpdateInfoXml(); string autoUpdateInfoXmlPath = Path.Combine(AppConfig.Instance.TempPath, GlobalParam.AutoUpdateInfo_XmlFileName); string argument1 = autoUpdateConfigXmlPath; string argument2 = autoUpdateInfoXmlPath; string argument3 = GlobalParam.MainProcess; string argument4 = GlobalParam.RemoteDir; string arguments = argument1 + " " + argument2 + " " + argument3 + " " + argument4; Process.Start("AutoUpdater.exe", arguments); Application.Exit(); } } catch (TimeoutException) { blFinish = false; } catch (WebException) { blFinish = false; } catch (Exception) { blFinish = false; } return blFinish; #endregion } /// <summary> /// UI執行緒未捕獲異常處理 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private static void Application_ThreadException(object sender, ThreadExceptionEventArgs e) { string strError = "", strLog = "", strDateInfo = DateTime.Now.ToString() + " 出現應用程式未處理的異常：\r\n"; var error = e.Exception; if (error != null) { strError = strDateInfo + $"異常型別：{error.GetType().Name}\r\n異常訊息：{error.Message}"; strLog = strDateInfo + $"異常型別：{error.GetType().Name}\r\n異常訊息：{error.Message}\r\n堆疊資訊：{error.StackTrace}\r\n來源資訊：{error.Source}\r\n"; } else { strError = $"Application ThreadException：{e}"; } WriteLog(strLog); MessageBox.Show(strError, "系統錯誤", MessageBoxButtons.OK, MessageBoxIcon.Error); } /// <summary> /// 非UI執行緒未捕獲異常處理 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e) { string strError = "", strLog = "", strDateInfo = DateTime.Now.ToString() + " 出現應用程式未處理的異常：\r\n"; if (e.ExceptionObject is Exception error) { strError = strDateInfo + $"異常訊息：{error.Message}"; strLog = strDateInfo + $"異常訊息：{error.Message}\r\n堆疊資訊：{error.StackTrace}"; } else { strError = $"Application UnhandledError：{e}"; } WriteLog(strLog); MessageBox.Show(strError, "系統錯誤", MessageBoxButtons.OK, MessageBoxIcon.Error); } /// <summary> /// 寫入日誌 /// </summary> /// <param name="strLog"></param> private static void WriteLog(string strLog) { string dirPath = @"Log\MainProcess", fileName = DateTime.Now.ToString("yyyy-MM-dd") + ".txt"; string strLine = "----------------------------------------------------------------------------------------------------"; FileUtility.WriteFile(Path.Combine(dirPath, fileName), strLog); FileUtility.WriteFile(Path.Combine(dirPath,fileName), strLine); } }Program.cs

7.3、Window窗體
1）新建一個Windows窗體Main。
public partial class Main : Form { //自動更新目錄路徑 private static readonly string AutoUpdateDirPath = Application.StartupPath + @"\" + GlobalParam.AutoUpdateDir; //自動更新資訊XML檔案路徑 private static readonly string AutoUpdateInfoXmlPath = Path.Combine(AutoUpdateDirPath, GlobalParam.AutoUpdateInfo_XmlFileName); //自動更新檔案目錄路徑 private static readonly string RemoteDirPath = Application.StartupPath + @"\" + GlobalParam.AutoUpdateDir + @"\" + GlobalParam.RemoteDir; public Main() { InitializeComponent(); } /// <summary> /// 窗體載入 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void Main_Load(object sender, EventArgs e) { if (!Directory.Exists(RemoteDirPath)) { Directory.CreateDirectory(RemoteDirPath); } LoadBaseInfo(); LoadDirectoryFileList(); } /// <summary> /// 重新整理 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void btnRefresh_Click(object sender, EventArgs e) { LoadBaseInfo(); LoadDirectoryFileList(); } /// <summary> /// 初始化 /// </summary> private void LoadBaseInfo() { dtUpdateTime.Text = DateTime.Now.ToString("yyyy-MM-dd"); txtNewVersion.Text = GetMainProcessFileVersion(); CreateHeaderAndFillListView(); } /// <summary> /// 獲取主程式檔案版本 /// </summary> /// <returns></returns> private string GetMainProcessFileVersion() { string fileVersion = ""; if (File.Exists(RemoteDirPath + "\\" + GlobalParam.MainProcess + ".exe")) //如果更新中有主程式檔案 { FileVersionInfo info = FileVersionInfo.GetVersionInfo(RemoteDirPath + "\\" + GlobalParam.MainProcess + ".exe"); fileVersion = info.FileVersion; } return fileVersion; } /// <summary> /// 新增ListView列名 /// </summary> private void CreateHeaderAndFillListView() { lstFileList.Columns.Clear(); int lvWithd = lstFileList.Width; ColumnHeader columnHeader; //First Header columnHeader = new ColumnHeader { Text = "#", Width = 38 }; lstFileList.Columns.Add(columnHeader); //Second Header columnHeader = new ColumnHeader { Text = "檔名", Width = (lvWithd - 38) / 2 }; lstFileList.Columns.Add(columnHeader); //Third Header columnHeader = new ColumnHeader { Text = "更新路徑", Width = (lvWithd - 38) / 2 }; lstFileList.Columns.Add(columnHeader); } /// <summary> /// 載入目錄檔案列表 /// </summary> private void LoadDirectoryFileList() { if (!Directory.Exists(RemoteDirPath)) { Directory.CreateDirectory(RemoteDirPath); } FileHelper fileHelper = new FileHelper(RemoteDirPath); var fileArrary = fileHelper.GetUpdateList(fileHelper.GetAllFilesInDirectory(RemoteDirPath)).ToList(); var lastFile = fileArrary.FirstOrDefault(s => s == GlobalParam.MainProcess + ".exe"); //exe作為最後的檔案更新，防止更新過程中出現網路錯誤，導致檔案未全部更新。 if (lastFile != null) { fileArrary.Remove(lastFile); fileArrary.Add(lastFile); } PopulateListViewWithArray(fileArrary.ToArray()); } /// <summary> /// 使用路徑字元陣列填充列表 /// </summary> /// <param name="strArray"></param> private void PopulateListViewWithArray(string[] strArray) { lstFileList.Items.Clear(); if (strArray != null) { //只過濾根目錄下的特殊檔案 strArray = strArray.Where(s => !new string[] { GlobalParam.AutoUpdateInfo_XmlFileName }.Contains(s.Substring(s.IndexOf('\\') + 1))).ToArray(); for (int i = 0; i < strArray.Length; i++) { ListViewItem lvi = new ListViewItem { Text = (i + 1).ToString() }; int intStart = strArray[i].LastIndexOf('\\') + 1; lvi.SubItems.Add(strArray[i].Substring(intStart, strArray[i].Length - intStart)); lvi.SubItems.Add(strArray[i]); lstFileList.Items.Add(lvi); } } } /// <summary> /// 生成更新XML檔案 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void btnBuild_Click(object sender, EventArgs e) { if (string.IsNullOrEmpty(txtNewVersion.Text)) { MessageBox.Show("更新版本號不能為空。", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information); txtNewVersion.Focus(); return; } if (string.IsNullOrEmpty(txtMainProcessName.Text)) { MessageBox.Show("主程序名不能為空。", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information); txtMainProcessName.Focus(); return; } AutoUpdateInfo info = new AutoUpdateInfo() { NewVersion = txtNewVersion.Text.Trim(), UpdateTime = dtUpdateTime.Value.ToString("yyyy-MM-dd"), UpdateContent = txtUpdateContent.Text, FileList = lstFileList.Items.Cast<ListViewItem>().Select(s => s.SubItems[2].Text).ToList() }; string xmlValue = XmlUtility.Serializer(typeof(AutoUpdateInfo), info); using (StreamWriter sw = new StreamWriter(AutoUpdateInfoXmlPath)) { sw.WriteLine(xmlValue); sw.Flush(); sw.Close(); } MessageBox.Show("生成成功。", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information); } /// <summary> /// 開啟本地目錄 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void btnOpen_Click(object sender, EventArgs e) { ProcessStartInfo psi = new ProcessStartInfo("Explorer.exe") { Arguments = AutoUpdateDirPath }; Process.Start(psi); } }Main.cs
2）在bin\Debug\下新建一個AutoUpdateDir資料夾，然後再在AutoUpdateDir下新建一個AutoUpdateFiles資料夾。
3）在AutoUpdaterTest中，將程式集版本及檔案版本都改成1.0.0.1並重新生成，接著將AutoUpdaterTest.exe拷貝到AutoUpdateFiles下，最後將程式集版本及檔案版本都改回1.0.0.0。
4）此時執行AutoUpdateXmlBuilder，點選生成更新XML檔案即打包成功。程式會自動在AutoUpdateDir下生成打包資訊檔案AutoUpdateInfo.xml。
八、遠端服務端配置
注：此處為本機測試。
1）在某個碟符如E盤下新建一個AutoUpdate資料夾，將AutoUpdateXmlBuilder打包資料夾AutoUpdateDir拷貝到AutoUpdate資料夾下。
2）在IIS中新建一個網站，對應的虛擬目錄為E:\AutoUpdate，同時將埠設定為6600。
3）執行AutoUpdaterTest，如出現自動更新器即代表成功。
