Creating a Session for C#
To interact with a Universal Messaging Server, the first thing to do is create a Universal Messaging Session object, which is effectively your logical and physical connection to a Universal Messaging Realm. The steps below describe session creation.
1. Create a nSessionAttributes object with the RNAME value of your choice

string[] RNAME={"nsp://"};
nSessionAttributes nsa=new nSessionAttributes(RNAME);
2. Call the create method on nSessionFactory to create your session

Session mySession=nSessionFactory.create(nsa)
Alternatively, if you require the use of a session reconnect handler to intercept the automatic reconnection attempts, pass an instance of that class too in the create method:

public class myReconnectHandler : nReconnectHandler{
//implement tasks associated with reconnection

myReconnectHandler rhandler=new myReconnectHandler();
nSession mySession=nSessionFactory.create(nsa, rhandler);
3. Initialise the session object to open the connection to the Universal Messaging Realm

To enable the use of DataGroups and to create an nDataStream , you should pass an instance of nDataStreamListener to the init call.

public void SimpleStreamListener : nDataStreamListener{
//implement onMessage callback for nDataStreamListener callbacks

nDataStreamListener myListener = new SimpleStreamListener();
nDataStream myStream = mySession.init(myListener);
After initialising your Universal Messaging session, you will be connected to the Universal Messaging Realm. From that point, all functionality is subject to a Realm ACL check. If you call a method that requires a permission your credential does not have, you will receive an nSecurityException.
