using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using System.Management;

InitializeComponent();
}

[DllImport("user32.dll", EntryPoint = "ExitWindowsEx", CharSet = CharSet.Ansi)]
private static extern int ExitWindowsEx(int uFlags, int dwReserved);
//关机代码
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.StartInfo.CreateNoWindow = true;
myProcess.Start();
myProcess.StandardInput.WriteLine("shutdown -s -t 0");
}
}
}

Answer 2

楼上还那么多代码啊，其实就用2句代码就可以了：System.Diagnostics.Process p = new System.Diagnostics.Process(); p.Start("shutdown", "-s -t 0");
