Help with coding challenge try, catch

Need some help integrating the conditional if statement into a try, catch statement. Keeps giving me the error "I entered "25". I expected "Value is out of bounds!" but got "You entered 25" instead". . I've tried many variations of this and just not getting it. The instructions are not clear to me if they still need the conditional included in the answer or if the whole thing needs to be redone only using try, catch.

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

if (value > 0 || value < 20)
{
    Console.WriteLine(string.Format("You entered {0}",value));
}

}

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

Based on the query you provide, we can see that "if (value > 0 || value < 20)" - Meaning value is greater than 0 or value is smaller than 20, so when the user key in 25, it will prompt "You entered 25" because 25 is greater than 0. In order to use if statement to pass the challenges, you forget to add a else statement to print the error exception.

Let check back with the challenges it request you to prompt "Value is out of bounds!" when the user key in 25, you can do it like below code

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

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