Parameters

• key
  Type: System.String

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

• 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.

• timeout
  Type: System.TimeSpan

  The amount of time that the object should reside in the cache before expiration.

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.

The timeout value associated with the cached object overrides expiration settings specified in the named cache configuration.

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.
