    {
var push = (PushSharp.Android.GcmNotification)notification;
    json =Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic(push.JsonData);
    var NotificationID=json.NotificationID
    }

the code is not completed run it stopped at this line with no error and the function is exit, I can not get NotificationID in my variable

json =Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic(push.JsonData);

INotification is just an interface and the JsonData property is not part of that interface. The parameter instance passed in may not in fact be a GcmNotification type, so you should check to ensure it is and then case to it:

static void NotificationSent(object sender, INotification notification)
{
  var gcmNotification = notification as GcmNotification;
  if (gcmNotification != null) {
    var json = JObject.Parse (gcmNotification.JsonData);
    var notificationId = json["NotificationID"].ToString ();
  }
}
