really don't understand the question requirement

I'm sorry. But I really don't quite understand the requirement here?

Program.cs 
int value = int.Parse(Console.ReadLine());

    try {
        if(value>=0 && value<=20)
        {Console.WriteLine(string.Format("You entered {0}",value));}
        }

    catch
        {Console.WriteLine("The value is out of bounds!");}

The challenge asks you to throw an exception, it does not ask you to catch an exception. throwing exceptions is done by using the "throw new" keywords followed by the exception you want to throw an a pair of parenthesis like this:

throw new System.Exception();

In your code you check if the value is valid, but you don't throw any exception if it isn't. If you remove the try..catch block and just add an else clause to your if statement where you throw an exception as shown above, then you will be able to pass the challenge.
