Silverlight中利用WCF获取客户端IP

public class Service1 : IService1
{
     public string DoWork()
     {
        OperationContext operationContext = OperationContext.Current;
        MessageProperties messageProperties = operationContext.IncomingMessageProperties;
        RemoteEndpointMessageProperty remoteEndpointProperty = messageProperties[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty;
 
        return string.Format("Your IP address is {0} and your port is {1}",remoteEndpointProperty.Address, remoteEndpointProperty.Port);
     }
}



public partial class Page : UserControl
{
    public Page() 
    {
          InitializeComponent();
          ServiceReference1.Service1Client client=new GridSplitterSample.ServiceReference1.Service1Client();
          client.DoWorkCompleted += new EventHandler<GridSplitterSample.ServiceReference1.DoWorkCompletedEventArgs>(client_DoWorkCompleted);
          client.DoWorkAsync();
   }
 
   void client_DoWorkCompleted(object sender, GridSplitterSample.ServiceReference1.DoWorkCompletedEventArgs e)
   {
        TextBlock myBlock=new TextBlock();
        myBlock.Text=e.Result;
        LayoutRoot.children.Add(myBlock);
   }
}
