Implements

A key cannot be , but a value can be, if the type of values in the list, TValue, is a reference or NullableT type.

If the key is not found when a value is being retrieved, KeyNotFoundException is thrown. If the key is not found when a value is being set, the key and value are added.

You can also use this property to add new elements by setting the value of a key that does not exist in the StringKeyedDictionaryTValue, for example:

myDictionary["myNonexistentKey"] = myValue;

Getting or setting this property approaches an O(1) operation.
