How do I get the mailbox and the name of all of the participants of an appointement?

I am working with an Exchange web service, and I want to get the mailbox and the name of all the participants of an appointment.

I do this using:

for开发者_如何学编程each (Attendee participant in appointment.RequiredAttendees)
{
    Console.WriteLine("Attendee {0}", participant.Name);
}

and it returns me nothing.

RequiredAttendees is a string. You need the Recipients collection.
