User role based show/hide few methods in ASMX/WCF service?

Question

Hi Say for example I have an ASMX service or a WCF service with say 50 methods. Now based on the user who is trying to access the web service I would like to hide few methods. Like for example say a Level 1 user gets access to only 10 methods from the 50 methods level 2 user gets access to 30 methods and a level 3 user gets access to all the methods. Is this possible? Or do I need to create separate web services for each level user? Thanks!

So you dont need separate service for every user. You can configure service and restrict in config file e.g location path = WebServices > system.web > authorization > allow roles = Administrators WebServices /> deny users = * /> authorization > system.web > location > the other way is to decorate service  e.g. [ Authorize ( Roles = AuthorizedRole )]
