public override CacheItem GetCacheItem(
	string key,
	string regionName
)

Parameters

key
Type: System.String
A unique identifier for the cache entry to get.
regionName
Type: System.String
A named region in the cache to which a cache entry was added. Do not pass a value for this parameter. This parameter is null by default, because the MemoryCache class does not implement regions.

Return Value

Type: System.Runtime.Caching.CacheItem
A reference to the cache entry identified by key if the entry exists; otherwise, null.

ExceptionCondition
NotSupportedException

regionName is not null.

ArgumentNullException

key is null.

If the cache entry specified by key exists in the cache, the GetCacheItem method returns it as a CacheItem instance. The Key and Value properties of the CacheItem instance will be set. However, the RegionName property will be null, because regions are not implemented in the MemoryCache class.
