備註

ASP.NET 配置檔可用來儲存和擷取數據源中的用戶設定,例如資料庫。 使用目前 HttpContext的屬性來存取Profile使用者配置檔。 配置檔資訊和屬性值是使用配置檔提供者來管理。

類別 ProfileManager 可用來管理配置檔設定、搜尋使用者配置檔,以及刪除不再使用的使用者配置檔。 類別 ProfileManager 提供靜態方法和屬性,可藉由在應用程式程式代碼中參考 ProfileManager 類別來存取。 如需範例,請參閱本主題中的一節,以及類別成員 ProfileManager 主題中的其他範例。

根據預設,所有 ASP.NET 應用程式都會停用使用者配置檔。 若要啟用使用者配置檔,請將enabled配置檔組態專案的 屬性設定為 true,如下列範例所示。

<configuration>
  <system.web>
    <profile enabled="true" />
  </system.web>
</configuration>

如需使用者配置檔的詳細資訊,請參閱 ASP.NET 配置檔屬性概觀

配置檔提供者可用來儲存和擷取使用者配置檔中的屬性。 .NET Framework 包含類別 SqlProfileProvider ,此類別會將使用者配置檔屬性儲存在 SQL Server 資料庫中。 SqlProfileProvider名為 AspNetSqlProvider 的實例會在計算機組態中指定為預設配置檔提供者。 實例 AspNetSqlProvider 會連線到本機網頁伺服器上的 SQL Server 資料庫。 您可以使用提供者組態專案和defaultProvider配置檔組態項目的 屬性,指定SqlProfileProvider連接到另一個 SQL Server 做為預設配置檔提供者的 ,如下列範例所示。

<configuration>
  <connectionStrings>
    <add name="SqlServices" connectionString=
      "Data Source=MySqlServer;Integrated Security=SSPI;Initial Catalog=aspnetdb;" />
  </connectionStrings>
  <system.web>
    <profile defaultProvider="SqlProvider">
      <providers>
        <clear />
        <add name="SqlProvider"
          type="System.Web.Profile.SqlProfileProvider"
          connectionStringName="SqlServices"
          applicationName="MyApplication" />
      </providers>
    </profile>
  </system.web>
</configuration>

屬性

擷取上次活動日期發生在指定的日期和時間或之前的設定檔之所有使用者設定檔資料。

GetAllInactiveProfiles(ProfileAuthenticationOption, DateTime, Int32, Int32, Int32)

擷取使用者設定檔之 ProfileInfo 物件的某個頁面,其中設定檔的上次活動日期發生在指定的日期和時間或之前。

GetAllProfiles(ProfileAuthenticationOption)

擷取資料來源中設定檔的使用者設定檔資料。

GetAllProfiles(ProfileAuthenticationOption, Int32, Int32, Int32)

擷取使用者設定檔資料的頁面。

GetNumberOfInactiveProfiles(ProfileAuthenticationOption, DateTime)
