跨线程访问控件

时间：2010-08-31 来源：iceknp

跨线程访问控件，定义一个委托，委托指向的是该方法，然后使用Invoke方法调用这个委托。

代码

private Thread thdSample;

private void btnReceive_Click(object sender, EventArgs e)
{
    thdSample = new Thread(new ThreadStart(thdSampleRun));
    thdSample.Start();
}

public void thdSampleRun()
{
    SetReceiveText();
}

public delegate void SetReceiveTextEventHandler();

public void SetReceiveText()
{
    if (this.InvokeRequired)
    {
        SetReceiveTextEventHandler handler = 
            new SetReceiveTextEventHandler(SetReceiveText);
        this.Invoke(handler, new object[] { });
    }
    else
    {
        lock (rtbReceive)
        {
            rtbReceive.AppendText("跨线程调用主线程控件...");
            rtbReceive.AppendText("\n");
        }
        thdSample.Abort();
    }
}
