public DataCacheItemVersion Add(
	string key,
	Object value,
	TimeSpan timeout,
	string region
)

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.

The object saved to the cache.
timeout

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

The name of the region to save the object.

Return Value

Type: Microsoft.ApplicationServer.Caching..::..DataCacheItemVersion
A DataCacheItemVersionobject that represents the version of the object saved to the cache under the key value.
