Try/Catch block isn't being evaluated.

I implemented the try/catch block as requested but the program isn't able to evaluate it.

Is there a way to fix this?

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

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

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

If you haven't brought in System with a using System; statement at the top then your problem is Console.WriteLine is missing System.Console.WriteLine. Also, make sure there isn't any punctuation missing. I don't remember if there was a requirement for a period or exclamation mark at the end but you have one on the exception but not for the try block.

Your Try/Catch code is correct, but you have wrapped it around the wrong code. The challenge asks you to:

wrap the testing logic with a try/catch

The "testing logic" is the if statement that verifies that the value passed in is correct.

If you simply take your Try/Catch block and wrap it arund the if statement instead of the print statement like this:

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

try 
{
    if (value < 0 || value > 20)
    {
        throw new System.Exception();
    }
}
catch(Exception) 
{
    System.Console.WriteLine("Value is out of bounds!");
}

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

Then your code will pass.
