Best way to do it is using enumeration:
enum TwoValueType { Zero, One, }
int initialValue = (int)TwoValueType.Zero;
If you need numeric type such as int, you will have to type cast like in the last line in the code sample above.
Honestly, remove your constructor and destructor already, and never write them again! Write only the constructor when you need to do something. Never use destructor unless you understand very well why doing so.
