says no catch was added , why?

i dont know why it says error "Did you add a catch?"

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

if (value < 0 || value > 20)
{
    throw new System.Exception();
}
try
{

}
catch(Exception)
{ 
   Console.WriteLine("Value is out of bounds!");
}
Console.WriteLine(string.Format("You entered {0}",value));

The message is a bit unhelpful. You certainly do have a "catch", but since the code that needs to be tested is not inside the "try" block, the catch is never triggered.

Just move the if/throw code inside the "try" and you should be gold!
