Membership.GetAllUsers Method
Visual Studio 2010
Gets a collection of all the users in the database.
Assembly: System.Web (in System.Web.dll)
Return Value
Type: System.Web.Security.MembershipUserCollectionA MembershipUserCollection of MembershipUser objects representing all of the users in the database.
GetAllUsers returns the information for all membership users for an application as a collection of MembershipUser objects. Be careful when using the GetAllUsers method with very large user databases, as the resulting MembershipUserCollection in your ASP.NET page may degrade the performance of your application.
The following code example returns a list of users with a count of the number of users currently online.
