SqlMembershipProvider.GetAllUsers(Int32, Int32, Int32) 方法

定義

取得 SQL Server 成員資格資料庫中所有使用者的集合。

public:
 override System::Web::Security::MembershipUserCollection ^ GetAllUsers(int pageIndex, int pageSize, [Runtime::InteropServices::Out] int % totalRecords);
public override System.Web.Security.MembershipUserCollection GetAllUsers (int pageIndex, int pageSize, out int totalRecords);
override this.GetAllUsers : int * int * int -> System.Web.Security.MembershipUserCollection
Public Overrides Function GetAllUsers (pageIndex As Integer, pageSize As Integer, ByRef totalRecords As Integer) As MembershipUserCollection

參數

pageIndex
Int32

要傳回的結果網頁索引。 pageIndex 以零為起始。

pageSize
Int32

要傳回的結果網頁大小。

totalRecords
Int32

使用者的總數。

傳回

MembershipUserCollection 物件的 MembershipUser,表示已設定 ApplicationName 之資料庫中的所有使用者。

例外狀況

pageIndex 小於零。

-或-

pageSize 小於一。

-或-

pageIndexpageSize 以加 pageSize 減一超過 Int32.MaxValue

範例

下列程式代碼範例會傳回數據頁面中的使用者清單,其中包含目前在線用戶的數目。

注意

這個範例會 Membership 使用 類別呼叫 SqlMembershipProvider 指定做為 defaultProvider Web.config 檔案中的 。 如果您需要存取預設提供者做為 類型 SqlMembershipProvider,您可以轉換 Provider 類別的 Membership 屬性。 若要以特定提供者類型存取其他已設定的提供者,您可以使用 類別 ProvidersMembership 屬性來存取這些提供者,並將其轉換成特定提供者類型。

備註

類別會 Membership 呼叫這個方法,以從 ASP.NET 應用程式組態檔 (Web.config) 中指定的 SQL Server 資料庫擷取使用者資訊。

GetAllUsers 回的結果受限於 pageIndexpageSize 參數。 參數pageSize會識別 在中MembershipUserCollection傳回的物件MembershipUser數目上限。 參數 pageIndex 會識別要傳回的結果頁面,其中零會識別第一頁。 參數 totalRecords 是參數 out ,其設定為所設定 applicationName的成員資格用戶總數。 例如,如果已設定 applicationName的使用者有13個,且 pageIndex 值為1且 pageSize 值為5,則 MembershipUserCollection 傳回的會包含第六個到第十個傳回的使用者。 參數 totalRecords 會設定為 13。
