how can I parse an enum from its value?

[Hampster]

enum ABC {a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z} 

Console.WriteLine("Give me a number 0-25 and I'll give you the letter: ");
int x=Convert.ToInt16(Console.ReadLine());
ABC e=(ABC)x;
Console.WriteLine(Convert.ToInt16(e)+"="+e.ToString());
