C# Enums – Getting the Integer Value from Enum

c++enums

I am working on a basic Battleship game to help my C# skills. Right now I am having a little trouble with enum. I have:

enum game : int
{
    a=1,
    b=2,
    c=3,
}

I would like the player to pass the input "C" and some code return the integer 3. How would I set it up for it to take a string var (string pick;) and convert it to the correct int using this enum? The book I am reading on this is bit confusing

Just parse the string and cast to int.

var number = (int)((game) Enum.Parse(typeof(game), pick));

Just cast the enum, e.g.

int something = (int) Question.Role;

The above will work for the vast majority of enums you see in the wild, as the default underlying type for an enum is int.

However, as cecilphillip points out, enums can have different underlying types. If an enum is declared as a uint, long, or ulong, it should be cast to the type of the enum; e.g. for

enum StarsInMilkyWay:long {Sun = 1, V645Centauri = 2 .. Wolf424B = 2147483649};

you should use

long something = (long)StarsInMilkyWay.Wolf424B;
