asp.net - How to access informations of the membership users with MVC4 -

i have website member section. there's admin manage users. want admin sees informations of other users, username , email.

for now, registration page asks users username, password , email following this tutorial. memorises in db find, in userprofile table. problem access them. knew how mvc3 membership.getallusers().cast<membershipuser>() , where specify request.

but, in mvc4, membership.getallusers() not permitted understand. have tried lot of different ways found on web, none solve problem. best i've found username, found in post :

var model = roles.getusersinrole("statuswaiting").select(membership.getuser).tolist();

where "statuswaiting" role of users in db. but, (and others same result), have emailid appears in model, empty.

does know how achieve this? i'm still looking haven't found yet.

edit : if there's way achieve i'm mind opened

edit2 : line above, membershipuser fields : comment, creationdate,email,isapproved,..., providername,...,username. strating think table put email @ registration not same 1 i'm trying informations. don't figure out 1 else be

if role "statuswaiting" can roles using:

var model = roles.getusersinrole("statuswaiting"); //note case 

if db populated correctly, error query.

edit:

the method signature default role provider is:

public string[] getusersinrole(string rolename) 

that's reason username in query. if want more data query db directly, without using role provider. code 1 below should help.

var query = db.usertablename.where(x => x.role == "statuswaiting");
