如何用C#命令关机？

[yuhao210]

我用using System.Runtime.InteropServices ;
using System.Text ;
[ DllImport("user32") ]
public static extern long ExitWindowsEx(long uFlags, long dwReserved ) ;
ExitWindowsEx(1, 0);
怎么没有反应
用ExitWindowsEx(0, 0)；是注销

我手上到是有一个，也是网上下的，记得以前我发过贴，你找一下好了

楼主可以试试在c#里面执行cmd命令
命令为shutdown -s
偶没试过哈
只知道C#可以跑cmd命令

C#调用API关机:

namespace ShutDownTest {


using System;

using System.Drawing;

using System.Collections;

using System.ComponentModel;

using System.Windows.Forms;

using System.Data;

using System.Runtime.InteropServices;

using System.Security.Principal;


[StructLayout(LayoutKind.Sequential, CharSet=CharSet.Auto)]

public struct LUID

{

public uint LowPart;

public uint HighPart;

};


[StructLayout(LayoutKind.Sequential, CharSet=CharSet.Auto)]

public struct TOKEN_PRIVILEGES

{

public uint PrivilegeCount;

public LUID Luid;

public uint Attributes;

};


public class PlatformImport

{

[DllImport("advapi32", CharSet=CharSet.Auto)]

public static extern bool LookupPrivilegevalue (string sysname,string privname,ref LUID luid);


[DllImport("advapi32", CharSet=CharSet.Auto)]

public static extern bool AdjustTokenPrivileges(IntPtr handle, bool dsall,ref TOKEN_PRIVILEGES newstate,int len, IntPtr oldstate,IntPtr retlen);


[DllImport("kernel32.dll")]

public static extern int GetLastError();



[DllImport("user32.dll")]

public static extern bool ExitWindowsEx(int uFlags, int dwReason);

}


public class Form1 : Form

{

private Button button1;


public Form1()

{


this.button1 = new System.Windows.Forms.Button();

this.SuspendLayout();


this.button1.Location = new Point(136, 112);

this.button1.Name = "button1";

this.button1.Size = new Size(80, 24);

this.button1.TabIndex = 0;

this.button1.Text = "Shut Down";

this.button1.Click += new EventHandler(this.button1_Click);


this.AutoScaleBaseSize = new Size(6, 14);

this.ClientSize = new Size(292, 273);

this.Controls.Add(button1);

this.Name = "Form1";

this.Text = "shutdown test";

this.ResumeLayout(false);

}


[STAThread]

static void Main()

{

Application.Run(new Form1());

}


private void button1_Click(object sender, System.EventArgs e)

{

WindowsIdentity identity = WindowsIdentity.GetCurrent();

IntPtr token = identity.Token;

IntPtr luid = (IntPtr)0;

IntPtr previousState = (IntPtr)0;

IntPtr previousStateLength = (IntPtr)0;

LUID privilegeId = new LUID ();

PlatformImport.LookupPrivilegevalue ("", "SeShutdownPrivilege", ref privilegeId);


TOKEN_PRIVILEGES privileges = new TOKEN_PRIVILEGES();

privileges.PrivilegeCount = 1;

privileges.Luid = privilegeId;

privileges.Attributes = 2;

PlatformImport.AdjustTokenPrivileges (token, false, ref privileges, Marshal.SizeOf(privileges), previousState, previousStateLength);


if (PlatformImport.GetLastError() != 0) return;


if(!(PlatformImport.ExitWindowsEx(0x01 | 0x04, 0))) return;

}

}

}

在2000以后你要获取SeShutdownPrivilege权限
