Example

The example code instantiates an IMessengerGroups object, localGroups to hold the value of the IMessenger2::MyGroups property on the Messenger object, communicator. The number of groups in the collection is displayed on the application console with the value of the Count property.

Copy Code 
IMessengerGroups localGroups = (IMessengerGroups)communicator.MyGroups;
try
{
  if (localGroups != null)
  {
	 IMessengerGroup lastGroup = (IMessengerGroup)localGroups.Item(localGroups.Count - 1);
	 Console.WriteLine("Number of Groups: " + 
						localGroups.Count +
						" Last Group Name: " +
						lastGroup.Name
					);
  }
}
