C# C# Objects Inheritance Throwing Exceptions

Refusing to compile, am I reading the question wrong?

Challenge is: In the Program.cs file, write code to check if the value integer is less than 0 or greater than 20. Throw System.Exception if the value is outside of the range.

I take this to mean throw the exception if the value within the range [0,20]. Multiple refusing to compile snowballed into me creating the class to have it check in a separate method. I'm not sure if that's how it's supposed to be done. I'm at work and thus can't read the compile errors. Any directional help would be fantastic.

Program.cs
using System;

namespace Treehouse {
    class Program {
        static void Main() {
            int value = int.Parse(Console.ReadLine());
            Console.WriteLine(string.Format("You entered {0}",value));

            try{
                check(value);
            }//try
            catch(Exception){
                Console.WriteLine("That number is invalid");
            }//catch
        }//main
            public check(int value){
                if(value >= 0 && value <=20){
                    throw new Exception();
                }//if
            }//check
    }//class
}// namespace

You're working too hard! All you need for this challenge is a test ("if") and a throw. No need to create classes or methods.

But do notice that the instruction say to throw the exception "if the value is outside of the range.", so you'll need to revise the test expression.
