Is it a bug

This code should run, i have tried with catch(), catch(Exception), catch(System.Exception), using System. i get an error did you throw and error when value is less than 0 or greater than 20.

Program.cs 
int value = int.Parse(Console.ReadLine());
try
{
    if(value < 0 || value>20)
    {
        throw new System.Exception();
    }
}


catch(System.Exception)
{
    Console.WriteLine("The value is outside of the range");
}

Console.WriteLine(string.Format("You entered {0}",value));

You're working too hard! The instructions only asked for code to check the value and throw an exception if out of range.

You won't need a "try", "catch", or an additional "WriteLine" for this challenge.

ok, got it. I am revising the concepts so it was the natural progression to write it like this.

Thanks as always. Amit
