可能重复：
How to shutdown the computer from C#

我想在Win Form应用程序中发生事件后调出一个重启计算机消息框。如果用户选择是，我可以使用什么命令重新启动计算机？

Answer 1

你可以p/invoke ExitWindowsEx。

如上所述，您还需要拨打AdjustTokenPrivileges，因为SE_SHUTDOWN_NAME默认处于非活动状态。

Answer 2

你应该使用WINAPI。以下功能可以为您执行电源任务：

BOOL WINAPI ExitWindowsEx(
  _In_  UINT uFlags,
  _In_  DWORD dwReason
);

请注意，此功能位于user32.dll中。只需重新启动：

ExitWindowsEx(2,4);

以下是标志的完整列表：link to msdn

现在这里是示例C＃代码：

using System.Runtime.InteropServices;

[DllImport("user32.dll", SetLastError=true)]

public static extern bool  ExitWindowsEx(uint uFlags,uint dWReason);


public static void Main()
{
  ExitWindowsEx(2,4);
}

Answer 3

Process.Start("shutdown","/r /t 0");

Answer 4

这个特殊的解决方案对我有用：https://stackoverflow.com/a/102583/1505128

using System.Management;

void Shutdown()
{
    ManagementBaseObject mboShutdown = null;
    ManagementClass mcWin32 = new ManagementClass("Win32_OperatingSystem");
    mcWin32.Get();

    // You can't shutdown without security privileges
    mcWin32.Scope.Options.EnablePrivileges = true;
    ManagementBaseObject mboShutdownParams =
             mcWin32.GetMethodParameters("Win32Shutdown");

    // Flag 1 means we want to shut down the system. Use "2" to reboot.
    mboShutdownParams["Flags"] = "1";
    mboShutdownParams["Reserved"] = "0";
    foreach (ManagementObject manObj in mcWin32.GetInstances())
    {
        mboShutdown = manObj.InvokeMethod("Win32Shutdown", 
                                       mboShutdownParams, null);
    }
}
