C# C# Objects Inheritance Throwing Exceptions

Not sure what the objective of this task is. Or why this isn't working.

If I take the writeline out of the catch bracket, the prompt tells me it wrote 25 and nothing got printed. 25 is out of the range so why does it need to get printed?

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

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

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

You got too fancy. The challenge just wants you to perform the test and throw the exception if appropriate. You don't need the "try" and "catch" blocks.

Thanks for the reply Steven. Took out the try/catch and it worked.
