C# C# Objects Inheritance Catching Exceptions

Catching Exceptions

This is the prompt. "Here's how I wrote the code. 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."

it never gets to the catch part. I believe my conditions are right but it keeps running the code in the brackets of the if statement instead of going to the catch

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

try
{
    if (value > 0 && value < 20)
    {
        Console.WriteLine("you entered " + value);
    }
}
catch(System.Exception)
{
    Console.WriteLine("Value is out of bounds!");
}

One thing I noticed is your "&&" (which means and), should that not be "||" (which means or)?

Here are my edits:

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

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

The code originally provided had a "throw" statement that seems to have been deleted. It's the "throw" that causes the program flow to move the "catch" section.
