First :
Get all users, groups, roles from SharePoint.
Second:
When the users exist in you selected SPWeb object, all specific information should me inserted into generic class UserListCollection.
Third :
Example class below shows the algorithms, how you get the user information from ArrayList object and cast the object into UserListCollection.
