Getting a lot of errors when using ENUM types with SWITCH statements.

Question

public skin Diff
{
Easy,
Medium,
Hard
}
int health=0;
Diff pick =Console.Deadline();
switch(pick)
case Diff.Easy:
easy(); health=3;
break;
case Diff.Medium:
medium(); health =2;
break;
case Diff.Hard:
hard(); health=1;
break;
default:
easy(); health=3;
break;

The error codes are " invalid token ';' '=' in class, struct or interface declaration "
" ')' expected '{' expected " and are mostly within switch statement.
Do you see the problem, how would you do it?

Answer 1

//this way it would work
using System;
public enum Diff : int {Easy, Medium, Hard};

public class Program
{
public static void easy(){}
public static void medium(){}
public static void hard(){}

public static void Main()
{

int health=0;
Diff pick=(Diff) Int32.Parse(Console.ReadLine());
switch(pick)
{case Diff.Easy: easy();
health=3; break;
case Diff.Medium: medium();
health =2; break;
case Diff.Hard: hard();
health=1; break;
default: easy();
health=3; break;
}

}
}

Thanks I've learnt a lot

Answer 3

In summary the enumeration structure was intended for Programmer's convenience not user's. And it is more efficient to use strings to request text input. :)
