) : DataCacheItemVersion



The unique value that is used to identify the object in the cache.


The object to add or replace.


The DataCacheLockHandle object that was returned when the object was locked.


A list of tags to associate with the object.

Return Value

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 Expiration and Eviction.

Tags may only be used to retrieve a cached object if that object is stored in a region. This overload does not store the object in a region.

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.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
