C# - Can you call an Enum by the number value? [duplicate]

Question

If I have this code

//Spice Enums
enum SpiceLevels {None = 0 , Mild = 1, Moderate = 2, Ferocious = 3};

Which states the Enum Names + Their Number, how can I call an enum from a variable, say if a variable was 3, how do I get it to call and display Ferocious?

Answer 1

Just cast the integer to the enum:

SpiceLevels level = (SpiceLevels) 3;

and of course the other way around also works:

int number = (int) SpiceLevels.Ferocious;

See also MSDN:

Every enumeration type has an underlying type, which can be any integral type except char. The default underlying type of enumeration elements is int.

...

However, an explicit cast is necessary to convert from enum type to an integral type

Answer 2

enum SpiceLevels { None = 0, Mild = 1, Moderate = 2, Ferocious = 3 };
static void Main(string[] args)
{
    int x = 3;
    Console.WriteLine((SpiceLevels)x);
    Console.ReadKey();
}
