C#中worker线程与UI主线程通信

1. delegate(委托)

这个就类似C++中的函数指针的概念

2. Invoke

在worker线程中使用System.Windows.Forms.Control 的Invoke方法, 就可以与UI主线程进行通信

3. C#中向线程传递数据只有两种方法(<<Professional Csharp 2008的19.3.1给线程传送数据>>：

1) ParameterizedThreadStart

2)定制类

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

using System.Net;
using System.IO;
using System.Threading;

namespace Test
{
    public partial class main : Form
    {
        public main()
        {
            InitializeComponent();
            fun = Function;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Thread t1 = new Thread(MyThread);
            t1.Start(this);

        }
        private delegate void FunctionDelegate(string message);
        private void Function(string message)
        {
            this.textBox1.Text = message;
        }
        private FunctionDelegate fun;
        private void  MyThread(object o)
        {
           main UI = (main)o;
            UI.Invoke(UI.fun,new Object[] {"KKKKKKKKKKKKK"});

        }

    }
}
