備註
ASP.NET 設定檔用於儲存及檢索使用者設定,儲存在資料庫等資料來源中。 使用者設定檔是利用 Profile 目前 HttpContext的屬性存取的。 房況資訊與房產價值由房況提供者管理。
該 ProfileManager 類別用於管理個人檔案設定、搜尋使用者設定檔,以及刪除不再使用的使用者設定檔。 這個 ProfileManager 類別提供靜態的方法和屬性,可以透過應用程式程式碼中引用該 ProfileManager 類別來存取。 範例請參見本主題的範例部分,以及本課程成員 ProfileManager 的主題中其他範例。
預設情況下,所有 ASP.NET 應用程式的使用者設定檔都被停用。 要啟用使用者設定檔,請將設定檔設定元素的屬性設enabled為 true,如下範例所示。
<configuration>
<system.web>
<profile enabled="true" />
</system.web>
</configuration>
欲了解更多關於使用者設定檔的資訊,請參閱 ASP.NET 設定檔屬性概覽。
使用者設定檔提供者用於儲存和檢索使用者設定檔中的屬性。 .NET Framework 包含一個 SqlProfileProvider 類別,將使用者設定檔屬性儲存在 SQL Server 資料庫中。 機器設定中指定一個 SqlProfileProvider 名為 AspNetSqlProvider 實例的預設設定檔提供者。 實 AspNetSqlProvider 例會連接到本地網頁伺服器上的 SQL Server 資料庫。 你可以透過提供者的設定元素和defaultProvider設定檔元素的屬性,指定SqlProfileProvider一個連接另一個 SQL Server 的預設設定檔提供者,如下範例所示。
<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
| 名稱 | Description |
|---|---|
| ApplicationName |
取得或設定應用程式名稱,以儲存及檢索個人資料。 |
| AutomaticSaveEnabled |
會獲得一個值,表示使用者設定檔是否會在執行 ASP.NET 頁面結束時自動儲存。 |
| Enabled |
會取得一個值,表示該應用程式是否啟用了使用者設定檔。 |
| Provider |
會取得應用程式預設設定檔提供者的參考。 |
| Providers |
取得 ASP.NET 申請的個人資料提供者集合。 |
