How to shutdown the computer from C#

I want to bring up a restart computer message box after an event occurs in my Win Form application. What command can I use to restart the computer if the user chooses Yes?

Answer 1

您可以p/invokeExitWindowsEx。

如前所述，您还需要调用AdjustTokenPrivileges，因为SE_SHUTDOWN_NAME默认情况下是不活动的。

MSDN 上的一大堆信息在这里

Answer 2

你应该使用 WINAPI 。以下功能可以为您完成电源任务：

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

请注意，此函数位于 user32.dll 中。只需重新启动：

ExitWindowsEx(2,4);

这是标志的完整列表：链接到 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);
    }
}
