线程访问winform界面控件的例子

本例子主要是针对解决异常:

线程间操作无效: 从不是创建控件“richTextBox1”的线程访问它


关键看红色的代码,详细的查MSDN.


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 WindowsFormsApplication1
{
    public delegate void MyInitDelegate(RichTextBox myRtb, string strTemp);

    public partial class Form1 : Form
    {

        public Form1()
        {
            InitializeComponent();

        }

        private void Form1_Load(object sender, EventArgs e)
        {
            Thread t = new Thread(new ThreadStart(this.output));
            t.Start();
        }

        private void output()
        {
            string message = "pppp";
            this.richTextBox1.BeginInvoke(new MyInitDelegate(DelegateInitMethod), new object[] { this.richTextBox1, message });
        }

        public void DelegateInitMethod(RichTextBox myRtb, string strTemp)
        {
            myRtb.AppendText(System.Environment.NewLine + strTemp);
        }

    }
}
