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

Adds or replaces an object in the specified region if it is at the specified version. Specifies the timeout value of the cached object. This overload is not supported in Windows Azure Shared Caching.

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

Syntax

C++

JScript

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

Parameters

key: Type: System..::..String
The unique value that is used to identify the object in the region. Key names must be less than 65 KB.

value: Type: System..::..Object
The object to add or replace.

oldVersion: Type: Microsoft.ApplicationServer.Caching..::..DataCacheItemVersion
The DataCacheItemVersion object that represents the version of the cached object that is to be replaced.

timeout: Type: System..::..TimeSpan
The amount of time that the object should reside in the cache before expiration.

region: Type: System..::..String
The name of the region the object resides in.

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

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.
