1,546 PointsI dont know what is wrong with my code of the catch exception, pls help
The error seems to be in the catch line, I keep getting the reminder of adding a catch block for the exception, the example from the video is quite different from the one in the task I thing I'm doing sth wrong.
int value = int.Parse(Console.ReadLine());
if (value < 0 || value > 20)
{
throw new System.Exception();
}
Console.WriteLine(string.Format("You entered {0}",value));
try
{
value = 30;
}
catch (System.Exception)
{
Console.WriteLine("Value is out of bounds!");
}

The bit of code:
if (value < 0 || value > 20)
{
throw new System.Exception();
}
Is what is throwing the error. You need to catch that error if and when it is thrown. Simply setting Value = to something outside of the range 0 - 20, will not throw an error. The if statement is checking to see if the value is greater than 20 or less than 0. IF it IS, then it is throwing the System.Exception() exception. What you need to do is wrap a try/catch block around where said exception is being Thrown from.
try
{
if (value < 0 || value > 20)
{
throw new System.Exception();
}
}
catch (System.Exception ex)
{
Console.WriteLine("The value is out of bounds!");
}
That should do it!

Treehouse Moderator 145,860 PointsHi Eduardo,
I feel you may be overcomplicating the task. Basically all you need to do for this task is encapsulate the give code in the try/catch block.
The challenge didn't ask you to declare any values, so that line needs to be deleted first off. Next, you need to move the try block up to surround the if statement. If the if statement returns false (in bounds) it will jump and execute the Console.WriteLine to tell which value was entered.
If the if statements returns true (out of bounds), it will throw the error and jump to the catch block and return the line that states you are out of bounds.
Below is the corrected code for your reference. I hope it'll make sense. :)
int value = int.Parse(Console.ReadLine());
try {
if (value < 0 || value > 20)
{
throw new System.Exception();
}
Console.WriteLine(string.Format("You entered {0}",value));
} catch {
Console.WriteLine("Value is out of bounds!");
}
