C#编程应用--线程与委托

1. C#开发C/S程序，有时需要几个端，如服务器端，管理端，客户端等等， 端与端之间是不同线程或者进程，这就涉及跨线程调用的问题，

使用委托或者异步线程是必不可少的，这里是一个简单的委托线程，即通过委托调用另外一个线程；

2. 有图有真相：

3. 源码：

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 ThreadControlExample
{
    public partial class Form1 : Form
    {
        Thread thread1;
        Thread thread2;
        delegate void AppendStringDelegate(string str);
        AppendStringDelegate appendStringDelegate;
        public Form1()
        {
            InitializeComponent();
            appendStringDelegate = new AppendStringDelegate(AppendString);
        }

        private void AppendString(string str)
        {
           richTextBox1.Text += str;
        }

        private void Method1()
        {
            while (true)
            {
                Thread.Sleep(100);   //线程1休眠100毫秒
                richTextBox1.Invoke(appendStringDelegate, "a");
            }
        }
        private void Method2()
        {
            while (true)
            {
                Thread.Sleep(100);   //线程2休眠100毫秒
                richTextBox1.Invoke(appendStringDelegate, "b");
            }
        }

        private void buttonStart_Click(object sender, EventArgs e)
        {
            richTextBox1.Text = "";
            thread1 = new Thread(new ThreadStart(Method1));
            thread2 = new Thread(new ThreadStart(Method2));
            thread1.Start();
            thread2.Start();
        }

        private void buttonStop_Click(object sender, EventArgs e)
        {
            thread1.Abort();
            thread1.Join();
            thread2.Abort();
            thread2.Join();
            MessageBox.Show("线程1、2终止成功");
        }

    }
