DataCache.Put Method (String, Object, DataCacheItemVersion)

Adds or replaces an object in the cache if it is at the specified version.

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

Dim instance As DataCache
Dim key As String
Dim value As Object
Dim oldVersion As DataCacheItemVersion
Dim returnValue As DataCacheItemVersion

returnValue = instance.Put(key, value, oldVersion)

public DataCacheItemVersion Put (
	string key,
	Object value,
	DataCacheItemVersion oldVersion
public DataCacheItemVersion Put (
	String key, 
	Object value, 
	DataCacheItemVersion oldVersion
public function Put (
	key : String, 
	value : Object, 
	oldVersion : DataCacheItemVersion
) : DataCacheItemVersion



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


The object to add or replace.


The DataCacheItemVersion object that represents the version of the cached object that is to be replaced.

Return Value

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

By passing the oldVersion parameter, this method can maintain concurrency. If another process updates the cached object before this method is called, this method does not update the cached object and returns null. For more information about concurrency, see Concurrency Models and Concurrency Methods.
