Source:

MemoryCache.cs

Returns a set of cache entries that correspond to the specified keys.

public override System.Collections.Generic.IDictionary<string,object> GetValues (System.Collections.Generic.IEnumerable<string> keys, string regionName = default);

override this.GetValues : seq<string> * string -> System.Collections.Generic.IDictionary<string, obj>

Public Overrides Function GetValues (keys As IEnumerable(Of String), Optional regionName As String = Nothing) As IDictionary(Of String, Object)

Parameters

keys

IEnumerable<String>

A set of unique identifiers for the cache entries to return.

regionName

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.

Returns

IDictionary<String,Object>

A set of cache entries that correspond to the specified keys.

Exceptions

NotSupportedException

regionName is not null.

ArgumentNullException

keys is null.

ArgumentException

An individual key in the collection is null.

Remarks

If a cache entry that is represented by the keys does not exist, the corresponding value for the returned object in the dictionary is set to null. Therefore, the returned dictionary always has the same number of items as the number of elements in keys.
