SqlCacheDependency.GetUniqueID Method

Retrieves a unique identifier for a SqlCacheDependency object.

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

public override string GetUniqueID()

Return Value

Type: System.String
The unique identifier for the SqlCacheDependency object, or null if no identifier can be generated.

The SqlCacheDependency method returns an identifier used to uniquely track SqlCacheDependency objects associated with an item or application. The unique identifier generated when using table-based notifications is partially dependent on the change identifier generated by the database.

When using SQL Server 2005-based query notifications, the unique identifier is null because SQL Server 2005 does not support returning unique identifiers for individual query notifications.
