Getting all ids and usernames from membership Asp Net MVC

I have no doubt on how to retrieve membership id from 1 single user:

currentUser = Membership.GetUser(); 
Guid currentUserId = (Guid)currentUser.ProviderUserKey;

but I can´t find a way to retrieve all users id and usernames.

I tried this way:

MembershipUserCollection AllUsers;
AllUsers = GetAllUsers();

From that point I can´t find a way to retrieve Ids and Usernames from AllUsers. Could I get some help from here?

Solution

I think you're looking for Membership.GetAllUsers()

var users = Membership.GetAllUsers();
foreach (MembershipUser membershipUser in users)
{
    // membershipUser.UserName;
}
