c# - 在 Button 上关闭或重新启动本地计算机

Question

我做了一些谷歌搜索，似乎总是回到相同的解决方案，这似乎不起作用！

private void btnRestart_Click(object sender, EventArgs e)
{
    System.Diagnostics.Process.Start("Shutdown.exe", "/r /f /t 00");
}

private void btnShutdown_Click(object sender, EventArgs e)
{
    System.Diagnostics.Process.Start("Shutdown.exe", "/s /f /t 00");
}

CMD 出现一秒钟，然后关闭，没有做任何事情。我错过了什么吗？

Answer 1

这有点干净

using System.Runtime.InteropServices;

[DllImport("user32.dll", SetLastError = true)]
static extern int ExitWindowsEx(uint uFlags, uint dwReason);

ExitWindowsEx(1, 0); //this will cause the system to shut down.

ExitWindowsEx(2, 0); //this will cause the system to reboot.

Answer 2

这个答案是我从这里得到的。它对我有用。确保添加对System.Management

 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);
        }
    }

Answer 3

将这些命名空间添加到您的代码中

    using System.Diagnostics;
    using System.Runtime.InteropServices;

甚至这取决于您被分配了哪些权限。我希望这能帮到您。

Answer 4

根据shutdown /?，您不使用斜杠 (/) 而是使用破折号 (-)。

或者，尝试cmd.exe使用参数运行/c shutdown.exe /r /f /t 00

Answer 5

尝试使用ProcessStartInfo 传递参数：

ProcessStartInfo startInfo = new ProcessStartInfo("shutdown.exe");
startInfo.Arguments = "/r /f /t 00";
Process.Start(startInfo);
