Exception

Now wrap the testing logic with a try/catch and write the message "Value is out of bounds!" to the console if the exception is caught. I don't really understand where exactly to put try/catch, on my code below it doesn't work, can somebody please explain how it works?

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)
{
    Console.WriteLine("Value is out of bounds!");
}

You want to "try" the if statement, and "catch" the exception if it's thrown, printing out the out of bounds message. If the value is within the accepted range, the last line, which should be

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

will be executed instead. That last line needs to be outside the try/catch blocks. I'm sorry if that's not a great explanation, but hopefully it'll help a little.
