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

'Usage
Dim instance As DataCache
Dim key As String
Dim value As Object
Dim timeout As TimeSpan
Dim region As String
Dim returnValue As DataCacheItemVersion

returnValue = instance.Add(key, value, timeout, region)

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

Parameters

key

A unique value that is used to store and retrieve the object from the cache.

value

The object saved to the cache cluster.

timeout

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

region

The name of the region to save the object.

Return Value

A DataCacheItemVersionobject that represents the version of the object saved to the cache under the key value.

If an item using the same key is already present in the region, 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. For more information, see Expiration and Eviction. For more information about how to use this method, see How to: Add an Object to Cache.
