Put Method (String, Object, DataCacheItemVersion, TimeSpan)

Adds or replaces an object in the cache if it is at the specified version. Specifies the timeout value of the cached object.

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
)

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.

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.

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.
