关于跨线程访问控件
public partial class Form1 : Form
    {
        delegate void ChangeText();
        Thread s;
        public Form1()
        {
            InitializeComponent();
        }

        private void ChangeMyText()
        {
            if (textBox1.InvokeRequired)
            {
                textBox1.BeginInvoke(new ChangeText(ChangeMyText));
            }
            else
            {
                textBox1.Text += "CD ";
            }
        }
        private void Form1_Load(object sender, EventArgs e)
        {
            s = new Thread(new ThreadStart(XX));
            s.Start();
            
            
        }
        private void XX()
        {
            Thread.Sleep(10000);
            ChangeMyText();
        }
        private void CallBack(IAsyncResult result)
        {
 
        }
    }

最简单的办法就是直接修改最后的ChangeMyText方法，用异步调用自己就变成同步了。
