Parameters

key

Return Value

Type: Microsoft.ApplicationServer.Caching..::..DataCacheItemVersion
A DataCacheItemVersion object that represents the version of the cached object after it has been updated by this method.

Locked objects are never expired, but they may expire immediately if unlocked after their expiration time. For more information, see <maml:externalLink><maml:linkText>Expiration and Eviction</maml:linkText><maml:linkUri>http://go.microsoft.com/fwlink/?LinkID=193435</maml:linkUri></maml:externalLink>.

This overload is useful for updating the tags associated with the object. For more information about methods available for using tags, see <maml:externalLink><maml:linkText>Tag-Based Methods</maml:linkText><maml:linkUri>http://go.microsoft.com/fwlink/?LinkId=214985</maml:linkUri></maml:externalLink>.

If the lockHandle parameter is not equal to the DataCacheLockHandle object obtained from the method that is used to lock the object, a DataCacheException object is thrown with the ErrorCode property set to InvalidCacheLockHandle, and the object is not updated.
