c# - UCMA 4.0 How to get user name from PresenceNotificationRecieved Handler -

i using ucma 4.0 presence status of user. have defined event handler so

    _remotepresenceview.presencenotificationreceived += new eventhandler<         remotepresentitiesnotificationeventargs>(remotepresence_presencenotificationreceived); 

its implementation follows:

// event handler process remote target's presence notifications private void remotepresence_presencenotificationreceived(object sender,     remotepresentitiesnotificationeventargs e) {     console.writeline(string.format("presence notifications received target {0}", <<how username here>>         ));     // notifications contain notifications 1 user.     foreach (remotepresentitynotification notification in e.notifications)     {         if (notification.aggregatedpresencestate != null)         {             console.writeline("aggregate state = "                 + notification.aggregatedpresencestate.availability);         }     }     console.writeline("press enter delete contact, delete group, , unsubscribe "         + "presence of remote user.");  } 

my question how username person whos persence notification has changed in event handler code?

there contactcard property on remotepresentitynotification class provide various details including displayname in case need reference notification.contactcard.displayname.
