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);   }}
