Examples

The following code example shows the use of the SessionChangeReason enumeration in an implementation of the OnSessionChange method in a class derived from ServiceBase. This code example is part of a larger example provided for the ServiceBase class.

        // Handle a session change notice
        protected override void OnSessionChange(SessionChangeDescription changeDescription)

                " - Session change notice received: " +
                changeDescription.Reason.ToString() + "  Session ID: " +
                changeDescription.SessionId.ToString());
#endif
