範例
下列程式代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 資料庫數據表之間的關聯性。 類別的 SqlCacheDependency 實例必須監視數據表，以便在數據表變更專案時自動從快取中移除。
