wpf线程错误

问题描述

|

Thread thread;
OtherMonitor monitor;
public void StartRecieveData()
{
        System.Net.IPEndPoint iep = new IPEndPoint(IPAddress.Any,999);
        UdpClient client = new UdpClient(iep);
        client.Enablebroadcast = true;           
        string data = null;
        while (true)
        {                
            byte[] byteData = client.Receive( ref iep);
            data = Encoding.ASCII.GetString(byteData,byteData.Length);
            InsertDataToBase(data);
            UpdateSecondMonitor(data);
        }
}

private void Window_Loaded(object sender,RoutedEventArgs e)
{
 monitor = new OtherMonitor();
 monitor.Show();
 thread = new Thread(new ThreadStart(StartRecieveData));
 thread.IsBackground = true;
 thread.Start();           
}

InsertDataToBase(data) //  function  inserting record into Database
UpdateSecondMonitor(data) //- opened window on the second monitor,which  should be updated
{
  monitor.UpdateGrid();
}

在监视器窗口上尝试udate网格时出现的错误和错误： 调用线程无法访问该对象，因为其他线程拥有它 我尝试：

   //thread = new System.Threading.Thread(
   //         new System.Threading.ThreadStart(
   //         delegate()
   //         {
   //          races.dispatcher.Invoke(
   //            System.Windows.Threading.dispatcherPriority.normal,//                 new Action(delegate { StartRecieveData(); }));
   //         }

我不知道如何在“监视器”窗口中更新数据。 有人知道吗？     

解决方法

代替

UpdateSecondMonitor(data);

使用

this.Dispatcher.BeginInvoke(new Action<string>((data)=>UpdateSecondMonitor(data)));

确保UI在正确的线程上更新。
