Put Method (String, Object, DataCacheItemVersion, TimeSpan, IEnumerable(DataCacheTag))

Adds or replaces an object in the cache if it is at the specified version. Specifies the timeout value and associates tags with the cached object. Applies only to the server versions of AppFabric.

Namespace:  Microsoft.ApplicationServer.Caching
Assembly:  Microsoft.ApplicationServer.Caching.Client (in Microsoft.ApplicationServer.Caching.Client.dll)

public DataCacheItemVersion Put(
	string key,
	Object value,
	DataCacheItemVersion oldVersion,
	TimeSpan timeout,
	IEnumerable<DataCacheTag> tags


Type: System..::..String
The unique value that is used to identify the object in the cache.
Type: System..::..Object
The object to add or replace.
Type: Microsoft.ApplicationServer.Caching..::..DataCacheItemVersion
The DataCacheItemVersion object that represents the version of the cached object that is to be replaced.
Type: System..::..TimeSpan
The amount of time that the object should reside in the cache before expiration.
Type: System.Collections.Generic..::..IEnumerable<(Of <(<'DataCacheTag>)>)>
A list of tags to associate with the object.

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.

Tags may only be used to retrieve a cached object if that object is stored in a region. This overload does not store the object in a region.

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.

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