3）Form1.cs调用

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace test11
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private HideTaskmgrList _List = new HideTaskmgrList();
        private void Form1_Load(object sender, EventArgs e)
        {

            _List.Start();
        }
    }
}
