Assembly: Microsoft.ApplicationServer.Caching.Client (in microsoft.applicationserver.caching.client.dll)

Dim instance As DataCache
Dim key As String
Dim lockHandle As DataCacheLockHandle

public void Unlock (
	string key,
	DataCacheLockHandle lockHandle

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


The DataCacheLockHandle object that was returned when the object was locked

The lockHandle parameter is required and must match the DataCacheLockHandle of the locked object to succeed. For more information about concurrency, see Concurrency Models and Concurrency Methods.

Locked objects are never expired, but they may expire immediately if unlocked after their expiration time. For more information, see Expiration and Eviction.
