//在public partial class Form1 : Form里加这些

[DllImport("user32.dll")]

public static extern intFindWindow(string lpClassName, string lpWindowName);

[DllImport("User32.dll")]

public static extern Int32 SendMessage(

inthWnd, // handle to destination window

intMsg, // message

intwParam, // first message parameter

intlParam); // second message parameter

public Form1()

{

InitializeComponent();

}

//在private void Form1_Load(object sender, EventArgs e)里加这些

Process p = new Process();

p.StartInfo.WorkingDirectory = Environment.GetFolderPath(Environment.SpecialFolder.System); p.StartInfo.FileName = "taskmgr.exe";

p.StartInfo.CreateNoWindow = true;

p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;

p.Start();

在private void Form1_Load(object sender, EventArgs e)外面加这些private void Form1_FormClosing(object sender, FormClosingEventArgs e) {

constint WM_CLOSE = 0x0010;

inttaskManager = FindWindow("#32770", "Windows Task Manager");

SendMessage(taskManager, WM_CLOSE, 0, 0);

}
