C＃shutdown / hibernate / sleep

Question

是否可以使用C＃程序关闭/休眠/重启/睡眠计算机？

Answer 1

关闭/重启系统使用 -

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);
        }
    }

对于休眠和待机 - 如果您使用的是.NET 2.0，则可以直接调用 Application.SetSuspendState。

Answer 2

Process.Start("shutdown", "/s /t 0");  // shutdown
Process.Start("shutdown", "/r /t 0");  // shutdown and restart
Process.Start("shutdown", "/h /f");    // hibernate
