如何从 C# 应用程序启动 Windows XP 用户注销？我的应用程序的操作应该会产生与在 XP 开始菜单中单击“注销”相同的结果——如果系统要求确认就可以了。

是否有 .Net 或非托管 API 呢？

您可以 P/Invoke ExitWindowsEx：

http://www.pinvoke.net/default.aspx/user32/ExitWindowsEx.html

把它们放在一起：

using System.Runtime.InteropServices;
class Class1
{
    [DllImport("user32.dll")]
    static extern bool ExitWindowsEx(uint uFlags, uint dwReason);

    [STAThread]
    static void Main(string[] args)
    {
        ExitWindowsEx(ExitWindows.LogOff, ShutdownReason.MajorOther | ShutdownReason.MinorOther); 
    }
}

[Flags]
public enum ExitWindows : uint
{
   // ONE of the following five:
   LogOff = 0x00,
   ShutDown = 0x01,
   Reboot = 0x02,
   PowerOff = 0x08,
   RestartApps = 0x40,
   // plus AT MOST ONE of the following two:
   Force = 0x04,
   ForceIfHung = 0x10,
}

[Flags]
enum ShutdownReason : uint
{
    MajorApplication = 0x00040000,
    MajorHardware = 0x00010000,
    MajorLegacyApi = 0x00070000,
    MajorOperatingSystem = 0x00020000,
    MajorOther = 0x00000000,
    MajorPower = 0x00060000,
    MajorSoftware = 0x00030000,
    MajorSystem = 0x00050000,

    MinorBlueScreen = 0x0000000F,
    MinorCordUnplugged = 0x0000000b,
    MinorDisk = 0x00000007,
    MinorEnvironment = 0x0000000c,
    MinorHardwareDriver = 0x0000000d,
    MinorHotfix = 0x00000011,
    MinorHung = 0x00000005,
    MinorInstallation = 0x00000002,
    MinorMaintenance = 0x00000001,
    MinorMMC = 0x00000019,
    MinorNetworkConnectivity = 0x00000014,
    MinorNetworkCard = 0x00000009,
    MinorOther = 0x00000000,
    MinorOtherDriver = 0x0000000e,
    MinorPowerSupply = 0x0000000a,
    MinorProcessor = 0x00000008,
    MinorReconfig = 0x00000004,
    MinorSecurity = 0x00000013,
    MinorSecurityFix = 0x00000012,
    MinorSecurityFixUninstall = 0x00000018,
    MinorServicePack = 0x00000010,
    MinorServicePackUninstall = 0x00000016,
    MinorTermSrv = 0x00000020,
    MinorUnstable = 0x00000006,
    MinorUpgrade = 0x00000003,
    MinorWMI = 0x00000015,

    FlagUserDefined = 0x40000000,
    FlagPlanned = 0x80000000
}

尝试使用常量“EWX_LOGOFF”或 0 调用“ExitWindowsEx”API 函数。API 指南告诉我第二个参数被忽略。例如，

//The import
using System.Runtime.InteropServices;

// The declaration
[DllImport("user32.dll")]
public static extern int ExitWindowsEx(int uFlags, int dwReserved);

// The call
 ExitWindowsEx(0, 0);

为了完整起见，我发现最简单的方法是调用 Shutdown.exe（包含在 Windows 中）。

Process.Start("shutdown.exe", "-l -t 0");

这是 Cerebrus 建议的答案，只是 C# 形式。

塞勒布鲁斯是对的。这里有更多信息： .Net 中的锁定、注销、重启、关机、休眠、待机

或者你可以打电话：

shutdown.exe -l -t 0

如果你想要简单的出路。我自己使用 ExitWindowsEx。

由于某种原因，您无法-l与 with结合，-t因此这些将不起作用。唯一的方法似乎是前面提到的 P/Invoke。
