   if ( myMessagePartCollection->Contains( myMessagePart ) )
   {
      // Get the part named Body.
      Console::WriteLine( "Index of Body in MessagePart collection = {0}", myMessagePartCollection->IndexOf( myMessagePart ) );
      Console::WriteLine( "Deleting Body from MessagePart collection..." );
      myMessagePartCollection->Remove( myMessagePart );

   }
}
Console::WriteLine(S"Checking if message is AddHttpPostOut...");
Message* myMessage = myServiceDescription->Messages->Item[S"AddHttpPostOut"];

   MessagePart* myMessagePart = myMessage->Parts->Item[S"Body"];
   if (myMessagePartCollection->Contains(myMessagePart)) 
   {
      // Get the part named Body.
      Console::WriteLine(S"Index of Body in MessagePart collection = {0}",
         __box( myMessagePartCollection->IndexOf(myMessagePart)));
      Console::WriteLine(S"Deleting Body from MessagePart collection...");
