Question

Suspect my brain isn’t working today – I need to extract a list of keys, etc:

Dictionary<string, MyClass>  myDict;
List<String> myKeys = myDict.Keys;

The second line fails to compile as the Keys property returns a “KeyCollection” class and not a list<> of key objects.

Answer 1

Using LINQ you can do the following…

List<String> myKeys = myDict.Keys.ToList();

However depending on what your goal is with the keys (selective enumeration etc) it might make more sense to work with the key collection and not convert to a list.
