SqlCacheDependencyDatabase Class

Configures the SQL cache dependencies databases for an ASP.NET application. This class cannot be inherited.

Namespace:  System.Web.Configuration
Assembly:  System.Web (in System.Web.dll)

public sealed class SqlCacheDependencyDatabase : ConfigurationElement

The SqlCacheDependencyDatabase allows you to programmatically access and modify the databases element of the sqlCacheDependency node within the caching configuration section.

The SQL cache dependency allows the cached data to be synchronized with the original source. After you configure the relationship between an item stored in an ASP.NET application's cache and a specific SQL Server database table, an instance of the SqlCacheDependency class monitors the table for possible changes.

The following code example shows how to obtain the SqlCacheDependencyDatabase object from the configuration file of an existing Web application.

// Get the Web application configuration.
System.Configuration.Configuration webConfig =
WebConfigurationManager.OpenWebConfiguration("/aspnetTest");

// Get the section.
string configPath = "system.web/cache/sqlCacheDependency";
System.Web.Configuration.SqlCacheDependencySection sqlDs =
(System.Web.Configuration.SqlCacheDependencySection)webConfig.GetSection(
configPath);

// Get the databases element at 0 index.
System.Web.Configuration.SqlCacheDependencyDatabase sqlCdd =
    sqlDs.Databases[0];
