using protected methods in compact framework

Guest

I have managed to use the protected methods in the .net framework.. however i
need to use the protected method ".Client". so as to get the local endpoint
of the current connected socket.

this is the code

public class MyderivedTcpClient : TcpClient
{
// Constructor for the derived class.
public MyderivedTcpClient() : base ()
{
}

public String getAddress()
{
// Calls the protected 'Client' property belonging to the TcpClient base
class.
Socket s = this.Client;
return ((IPEndPoint)s.LocalEndPoint).ToString();
}

}

What solution could you suggest??

Thanks and regards

Well, Client is a private property and can not be accessed from derived
class. However, you can use reflection to achieve what you want:

System.Reflection.FieldInfo fi = typeof(TcpClient).GetField("Client",
System.Reflection.BindingFlags.NonPublic |
System.Reflection.BindingFlags.Instance);
Socket s = (Socket)fi.GetValue(this);
return ((IPEndPoint)s.LocalEndPoint).ToString();
