I am looking for a sample code on using GetInputBehavior  or  
GetOutputBehavior method on Pipeline class.

I saw the WSE 3.0 help documentation but it does not have sample except the
buit in

SecureConversationClientSendSecurityFilter which has one, but that does not
tell me how to

implement a class a reference to which can be retrieved from GetInputBehavior

from one on my own on a Custom policy assertion filter (inheriting from
SoapFilter).

Here is an example of the a code which I have created:

public interface ISomething
{

void SendData(string xmlData);

}

class SomeInputFilter: SoapFilter, ISomething
{

   // Implement the ISomething interface
   void ISomething.SendData(string xmlData)
   {
   ......    
   }
...
public override T GetBehavior<T>()

{

return (IDataTransfer)this;    // This gives a syntax error

?????      // What should be the implementation here to return instance of  
ISomething interface from the current instance of SomeInputFilter???

}

}

------------------------------------------------------------------------
Code on Service Client:
ISomething something =     (ISomething)PipeLine.GetInputBehavior<ISomething>
();    
----------------------------------------------------------------------------------

Thanks,
Mo
