public partial class Form1 : Form { private delegate void FlushClient();//代理 public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { Thread thread = new Thread(CrossThreadFlush); thread.IsBackground = true; thread.Start(); } private void CrossThreadFlush() { while (true) { //将sleep和无限循环放在等待异步的外面 Thread.Sleep(1000); ThreadFunction(); } } private void ThreadFunction() { if (this.textBox1.InvokeRequired)//等待异步 { FlushClient fc = new FlushClient(ThreadFunction); this.Invoke(fc);//通过代理调用刷新方法 } else { this.textBox1.Text = DateTime.Now.ToString(); } } } |
运行上述代码，我们可以看到问题已经被解决了，通过等待异步，我们就不会总是持有主线程的控制，这样就可以在不发生跨线程调用异常的情况下完成多线程对winform多线程控件的控制了
