Parameters
- key
- Type: System..::..Object
Key whose associated value is to be returned.
Return Value
The value to which this cache maps the specified key, or null if the cache contains no mapping for this key.Implements
IDictionary..::..Item[([( Object])])
Remarks
Returns null if the cache contains no mapping for this key. A return value of null does not necessarily indicate that the cache contains no mapping for the key; it's also possible that the cache explicitly maps the key to null.
The Contains(Object) operation may be used to distinguish these two cases.
Exceptions
Exception | Condition |
---|---|
System..::..InvalidCastException | If the key is of an inappropriate type for this cache. |
System..::..NullReferenceException | If the key is null and this cache does not permit null keys. |
