线程间访问控件的问题
线程间访问控件是不是要用代理？我在网上看到的方法，但是不行，不知道是不是我写错了，下面是相关代码希望大家给看看。

C# code

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;using System.Threading;namespace WindowsApplication3{    public partial class Form1 : Form    {        private Thread thread;                public Form1()        {            InitializeComponent();            //Control.CheckForIllegalCrossThreadCalls = false;                    }        delegate void mydel();        public void dele()        {            //Thread.Sleep(1000);            mydel d = new mydel(fun);            label1.Invoke(d);            //this.Invoke(d);        }        public void fun()        {            while (true)            {                int x = Convert.ToInt32(label1.Text);                x++;                label1.Text = Convert.ToString(x);                Thread.Sleep(1000);            }        }        private void Form1_FormClosing(object sender, FormClosingEventArgs e)        {            if (thread.IsAlive)                thread.Abort();        }        private void button1_Click(object sender, EventArgs e)        {            thread = new Thread(new ThreadStart(fun));            label1.Text = "0";            thread.Start();            button1.Enabled = false;            button2.Enabled = true;            button3.Enabled = false;            button4.Enabled = true;        }        private void button2_Click(object sender, EventArgs e)        {            thread.Suspend();            button1.Enabled = false;            button2.Enabled = false;            button3.Enabled = true;            button4.Enabled = false;        }        private void button3_Click(object sender, EventArgs e)        {            thread.Resume();            button1.Enabled = false;            button2.Enabled = true;            button3.Enabled = false;            button4.Enabled = true;        }        private void button4_Click(object sender, EventArgs e)        {            if (thread.IsAlive)            {                thread.Abort();                label1.Text = "";                button1.Enabled = true;                button2.Enabled = false;                button3.Enabled = false;                button3.Enabled = false;            }        }    }}
