Public Function PutAndUnlock (
    key As String,
    value As Object,
    lockHandle As DataCacheLockHandle,
    timeout As TimeSpan,
    region As String
) As DataCacheItemVersion

Parameters

  • key
    Type: System.String

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

  • timeout
    Type: System.TimeSpan

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

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

Remarks

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

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.
