Parameters

  • key
    Type: System.String

    A unique value that is used to store and retrieve the object from the cache. Key names must be less than 65 KB.

  • timeout
    Type: System.TimeSpan

    The amount of time 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 object saved to the cache under the key value.

Remarks

If an item using the same key is already present in the cache, this call throws an exception of type DataCacheException with the ErrorCode set to KeyAlreadyExists. The timeout value associated with the cached object overrides expiration settings specified in the named cache configuration.
