TValueCollection

Remarks

Empty value collections, such as new collections returned using this indexer when the key is not found, are not part of the dictionary until items are added to them. When the value collection becomes empty again, it is removed from the dictionary. Value collections stay synchronized with their dictionary to always reflect the values associated with their key inside the dictionary.
