How to use C # code to get your computer off, restart, logoff, lock, Hibernate, sleep

Brief introduction

This article describes how to use C # code to get your computer off, restart, logoff, lock, Hibernate, sleep.

How to implement first, use the using statement to add the namespaces we need:

usingSystem.Diagnostics;

usingSystem.Runtime.InteropServices;

Shutdown

The code is as follows:

Process.Start("shutdown","/s /t 0");    // 参数 /s 的意思是要关闭计算机

// 参数 /t 0 的意思是告诉计算机 0 秒之后执行命令

Restart

The code is as follows:

Process.Start("shutdown", "/r /t 0"); // 参数 /r 的意思是要重新启动计算机

Cancellation

You need to declare a Windows API function in your class using the DllImport method:

[DllImport("user32")]

publicstatic extern bool ExitWindowsEx(uint uFlags, uintdwReason);

You can then use the following code to implement logoff:

ExitWindowsEx(0,0);

Lock

As with logoff, you also need to declare a function:

[DllImport("user32")]

publicstatic extern voidLockWorkStation();

The lock can then be implemented using the following code:

LockWorkStation();

Sleep and sleep

Again, you need to declare a function:

[DllImport("PowrProf.dll", CharSet = CharSet.Auto, ExactSpelling = true)]

publicstatic extern bool SetSuspendState(bool hiberate, bool forceCritical, booldisableWakeEvent);

To implement hibernation, the code is as follows:

SetSuspendState(true, true, true);

To achieve sleep, the code is as follows:

SetSuspendState(false, true, true);
