Hi There, I think my Code is correct. I throw a new Exception, if the value is out of Range.

Pls have a look to my Program.cs i dont know what is wrong. I throw a new Exception and catch they with a Console.WriteLine Thank you

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

try 
{
    if (!(value <= 20 && value >= 0))
    {
      throw new System.Exception();

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

}
catch (System.Exception)
{
        Console.WriteLine("Wrong Range");

}

You did a bit too much!

What you did was very practical, but this challenge only wanted you to throw the exception, not catch it. I'd guess the tester evaluates your work by catching it itself.

Just remove your try and the entire catch block and you should pass.
