System.Web.Security Namespace
.NET Framework version 2.0
A collection of MembershipUser objects.
A System.Web.Security.MembershipUserCollection is returned from the GetAllUsers, FindUsersByName, and FindUsersByEmail methods of the System.Web.Security.Membership class. The MembershipUserCollection objects returned by the GetAllUsers, FindUsersByName, and FindUsersByEmail methods contain a snapshot of user information in the membership data store. That is, changes to the membership user information in a MembershipUserCollection are not reflected in the membership data store. To modify membership user information in the membership data store, use the UpdateUser, CreateUser and DeleteUser methods of the System.Web.Security.Membership class.
The following code example returns a list of membership users with a count of the number of users currently online. For an example of an ASP.NET application configured to use membership, see the Membership class.
Below is the HTML for the page.
