Parameters

• key
  Type: System.String

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

• value
  Type: System.Object

  The object to add or replace.

• lockHandle
  Type: Microsoft.ApplicationServer.Caching.DataCacheLockHandle

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

• tags
  Type: System.Collections.Generic.IEnumerable<DataCacheTag>

  A list of tags to associate with the object.

• region
  Type: System.String

  The name of the region the object resides in.

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.

Remarks

Locked objects are never expired, but they may expire immediately if unlocked after their expiration time.

This overload is useful for updating the tags associated with the object.

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.
