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, 0, 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网格时出错：调用线程无法访问此对象，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(); }));
   //         }

我不知道如何更新"监视器"窗口中的数据。也许有人知道？？

wpf线程错误

使用而不是UpdateSecondMonitor(data);

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

以确保UI在正确的线程上更新。
