i tried a couple of things, but I'm not sure i understand the question.
i cant just say
try { if(value < 0 || value < 20) } catch ......
int value = int.Parse(Console.ReadLine());
if (value < 0 || value > 20)
{
throw new System.Exception();
}
Console.WriteLine(string.Format("You entered {0}",value));

Also, don't forget that the "catch" block needs to output a new message.
