Remarks

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.

Applies to

GetAllUsers(Int32, Int32, Int32)

Gets a collection of all the users in the database in pages of data.

public:
 static System::Web::Security::MembershipUserCollection ^ GetAllUsers(int pageIndex, int pageSize, [Runtime::InteropServices::Out] int % totalRecords);

public static System.Web.Security.MembershipUserCollection GetAllUsers (int pageIndex, int pageSize, out int totalRecords);

static member GetAllUsers : int * int * int -> System.Web.Security.MembershipUserCollection

Public Shared Function GetAllUsers (pageIndex As Integer, pageSize As Integer, ByRef totalRecords As Integer) As MembershipUserCollection

Parameters

pageIndex: Int32

The index of the page of results to return. Use 0 to indicate the first page.

pageSize: Int32

The size of the page of results to return. pageIndex is zero-based.

totalRecords: Int32

The total number of users.

Returns

MembershipUserCollection

A MembershipUserCollection of MembershipUser objects representing all the users in the database for the configured applicationName.

Exceptions

Remarks

The results returned by GetAllUsers are constrained by the pageIndex and pageSize parameters. The pageSize parameter identifies the maximum number of MembershipUser objects to return in the MembershipUserCollection. The pageIndex parameter identifies which page of results to return, where 0 identifies the first page. The totalRecords parameter is an out parameter that is set to the total number of membership users for the configured applicationName. For example, if there are 13 users for the configured applicationName, and the pageIndex value was 1 with a pageSize of 5, the MembershipUserCollection returned would contain the sixth through the tenth users returned. totalRecords would be set to 13.
