源码如下：
using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;
namespace 关机重启
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
[DllImport("user32.dll", EntryPoint = "ExitWindowsEx", CharSet = CharSet.Ansi)]
private static extern int ExitWindowsEx(int uFlags,int dwReserved);
/// <summary>
/// 注销计算机
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button1_Click(object sender, EventArgs e)
{
ExitWindowsEx(0, 0);
}
/// <summary>
/// 关闭计算机
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button2_Click(object sender, EventArgs e)
{
System.Diagnostics.Process myProcess = new System.Diagnostics.Process();
myProcess.StartInfo.FileName = "cmd.exe";
myProcess.StartInfo.UseShellExecute = false;
myProcess.StartInfo.RedirectStandardInput = true;
myProcess.StartInfo.RedirectStandardOutput = true;
myProcess.StartInfo.RedirectStandardError = true;
myProcess.Start();
myProcess.StandardInput.WriteLine("shutdown -s -t 0");
}
/// <summary>
/// 重启计算机
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button3_Click(object sender, EventArgs e)
{
System.Diagnostics.Process myProcess = new System.Diagnostics.Process();
myProcess.StartInfo.FileName = "cmd.exe";
myProcess.StartInfo.UseShellExecute = false;
myProcess.StartInfo.RedirectStandardInput = true;
myProcess.StartInfo.RedirectStandardOutput = true;
myProcess.StartInfo.RedirectStandardError = true;
myProcess.StartInfo.CreateNoWindow = true;
myProcess.Start();
myProcess.StandardInput.WriteLine("shutdown -r -t 0");
}
}
}
以上是打开cmd.exe，然后写命令来实现关机等功能
