Log off user from Win XP programmatically in C#
提问by dbkk
How do I initiate a Windows XP user Log Off from a C# app? The action of my app should produce the same result as clicking "Log Off" in XP start menu -- it's fine if the system asks for a confirmation.
如何启动 Windows XP 用户从 C# 应用程序注销？我的应用程序的操作应该产生与在 XP 开始菜单中单击“注销”相同的结果——如果系统要求确认，那很好。
Is there a .Net or an unmanaged API for this?
是否有 .Net 或非托管 API？

You could P/Invoke ExitWindowsEx:
你可以 P/Invoke ExitWindowsEx：

Try calling the "ExitWindowsEx" API function with the constant "EWX_LOGOFF" or 0. API Guide tells me that the second parameter is ignored. For instance,
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);

Cerebrus is right. There's more info here: Lock, Logoff, Reboot, Shutdown, Hibernate, Standby in .Net
大脑是对的。这里有更多信息： .Net 中的锁定、注销、重启、关机、休眠、待机

Or you can just call:
或者你可以直接调用：
shutdown.exe -l -t 0
If you want the easy way out. I use the ExitWindowsEx myself.
如果你想要简单的出路。我自己使用 ExitWindowsEx。
回答by dbkk
For completeness, the simplest way I found is to call Shutdown.exe (included with Windows).
为了完整起见，我找到的最简单的方法是调用 Shutdown.exe（包含在 Windows 中）。
Process.Start("shutdown.exe", "-l -t 0");
This is the answer Cerebrus suggested, just in C# form.
这是 Cerebrus 建议的答案，只是采用 C# 形式。
回答by Tom
You can't combine -lwith -tfor some reason so those will not work. The only approach appears to be the aforementioned P/Invoke.
由于某种原因，您不能-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。
