使用C#代码安装、启动、停止、卸载Windows service(不使用InstallUtil.exe)

在调用 myAssemblyInstaller.Install(mySavedState);或myAssemblyInstaller.Uninstall(null);之后，该程序文件就不能被删除了，直到安装程序推出，而我想在卸载后立即更新程序文件，可是因为不能删除，也就替换不了了。那位知道解决方法？不妨回帖:)

 

 

 

通过.net reflector查看installutil.exe的源代码如下：

 

public static int Main(string[] args)
{
    Thread.CurrentThread.CurrentUICulture = CultureInfo.CurrentUICulture.GetConsoleFallbackUICulture();
    if (((Console.OutputEncoding.CodePage != 0xfde9) && (Console.OutputEncoding.CodePage != Thread.CurrentThread.CurrentUICulture.TextInfo.OEMCodePage)) && (Console.OutputEncoding.CodePage != Thread.CurrentThread.CurrentUICulture.TextInfo.ANSICodePage))
    {
        Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-US");
    }
    Assembly.GetEntryAssembly().GetCustomAttributes(typeof(AssemblyProductAttribute), true);
    Console.WriteLine(Res.GetString("InstallUtilSignOnMessage", new object[] { "2.0.50727.1433", CommonResStrings.CopyrightForCmdLine }));
    try
    {
        ManagedInstallerClass.InstallHelper(args);
    }
    catch (Exception exception)
    {
        Console.WriteLine(exception.Message);
        return -1;
    }
    return 0;
}

 

ManagedInstallerClass.InstallHelper()代码：

 

 

public static void InstallHelper(string[] args)

    bool flag = false;
    bool flag2 = false;
    TransactedInstaller installerWithHelp = new TransactedInstaller();

 实际上installutil.exe也是利用TransactedInstaller、AssemblyInstaller等类实现的。
