Entered "2", printed nothing... Catching Exceptions in C#

I cannot figure out where I'm going wrong here. I get no errors in the Preview. It looks like the variable VALUE is not meeting the criteria of the if statement.

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

try 
    {
        if (value < 0 || value > 20)
            {
                Console.WriteLine(string.Format("You entered {0}",value));
            }
    }
catch (System.Exception) 
    {
        Console.WriteLine(string.Format("Value is out of bounds!"));
    }

Two is printing nothing because you moved the Console.WriteLine inside of the if statement. So now it is printing a value only if the value is outside of the specified range. To get a value to print as expected, move the Console.WriteLine back outside of the if statement so it will print any number.

Then inside of the if statement, throw a System.Exception that will be caught when the number is out of range.
