How to fetch usersprofile under specific role

Hi all , thanks in advance ,

I want to display userprofile of those user who are under specific role like "administrators" ..........


I am using MembershipUserCollection class to store the usersprofile and to fill this object i use the Membership  , under which i  can only use GetAllUsers() , GetUserByName() or GetUserByEmail() fuctions but cant get users by role ......Please tell me a way around this problem

I am able to fetch usersname by using Roles.GetUserInRole("administrators")  but it only returns string[] of usernames which i dont know how to use to get the whole profile info..... i want the whole profile like the MembershipUserCollection does

See the code if u dont understand what i want
