Public Function Put (
    key As String,
    value As Object,
    oldVersion As DataCacheItemVersion,
    timeout As TimeSpan
) As DataCacheItemVersion

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.

  • 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.

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.
