c#多线程(三):跨线程访问

一效果

点击button1按钮后显示当前日期到 button1按钮上

二 代码

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Threading;using System.Windows.Forms;namespace WindowsFormsApplication1{    public partial class Form1 : Form    {        public Form1()        {                        InitializeComponent();                   }        private void Form1_Load(object sender, EventArgs e)        {                   }        private void button1_Click(object sender, EventArgs e)        {            Thread MyThread = new Thread(() =>            {                if (button1.InvokeRequired)//button1控件是不是当前线程创建的，明显不是当前线程创建的，返回true                {                    button1.Invoke(new Action(() => { button1.Text = DateTime.Now.ToString(); }));//调用Invoke函数进行跨线程访问                }                else                {                    this.button1.Text = DateTime.Now.ToString();                }                            });            MyThread.Start();                   }    }}
