Code is not working

What is wrong in this?

Program.cs 
int value = int.Parse(Console.ReadLine());
try
{
    if(value<0 || value>20)
        throw new Exception();
    else
        Console.WriteLine(string.Format("You entered {0}",value));
}
catch(Exception)
{
    Console.WriteLine("Wrong Value");
}

What you are doing is way outside the scope of the question. Right now you are exception handling, which is not what the question is asking for, instead the question is asking you to simply throw an error, not handle it. Also it is a poor coding standard to throw your exceptions within the try block.

Anyway back to the question: Just throw the error and you should be fine, don't worry about the try-catch yet.

If you can't figure out how to code it yourself without try-catch, here you go:

int value = int.Parse(Console.ReadLine());
if(value<0 || value>20) {
    throw new Exception();
}else {
   Console.WriteLine(string.Format("You entered {0}",value));
}
