C# C# Objects Inheritance Throwing Exceptions

Not sure when to use try/catch or if/else

On a very general level, I under try/catch, but I have a hard time separating it from the concept of if/else. This is where I'm at, but getting the error "Did you throw an exception when the value is less than 0 or greater than 20?"

Program.cs 
int value = int.Parse(Console.ReadLine());
if (value > 0 || value < 20)
{
    try
    {
    Console.WriteLine(string.Format("You entered {0}",value));
    }
    catch(System.Exception)
    {
    Console.WriteLine("Sorry, that value is outside the acceptable range.");
    }
}

In this challenge you only need "if". I see you have one already (but you may need to reverse the comparisons to fit the requirements), and inside the conditional block the challenge wants you to throw an exception.

And that's all there is to this one. You won't need a try/catch or "else" or any additional output statements.
