範例

下列程式碼範例示範如何從現有 Web 應用程式的組態檔取得 SqlCacheDependencySection 物件。

// Get the .<sqlCacheDependency> section
SqlCacheDependencySection sqlCacheDependency =
    cachingSectionGroup.SqlCacheDependency;

// Display one of its attributes.
msg = String.Format(
"Sql cache dependency enabled: {0}\n",
sqlCacheDependency.Enabled.ToString());

Console.Write(msg);

' Get the .<sqlCacheDependency> section
Dim sqlCacheDependency _
As SqlCacheDependencySection = _
cachingSectionGroup.SqlCacheDependency

' Display one of its attributes.
msg = String.Format( _
"Sql cache dependency enabled: {0}" + _
ControlChars.Lf, _
sqlCacheDependency.Enabled.ToString())

Console.Write(msg)

備註

SqlCacheDependencySection 物件參考組態檔的 sqlCacheDependency 區段。

SQL 快取相依性會建立儲存在 ASP.NET 應用程式快取中專案與特定SQL Server資料庫資料表之間的關聯性。 類別的 SqlCacheDependency 實例必須監視資料表，如此一來，當資料表變更時，系統會自動從快取中移除專案。
