What am I doing wrong here? Is there another file i need to look at?

When I try to compile, it goes to StudentCode.cs. How can i look at that file? Any help on this problem would be appreciated.

Thanks!

Program.cs 
using System;

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

if (value < 0 || value > 20)
{
    throw new System.Exception();
}

try
{
    int value = 25;
}

catch(Exception)
{
    Console.WriteLine("The Value is out of range.")
}

This is the namespace you use

using System;

value variable is declared which you named value, you read the value from the keyboard and convert to integer, assign to variable value

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

if the value variable value is less than zero or greater than 20 system will throw an exception if (value < 0 || value > 20) { throw new System.Exception(); }

we use the try catch blocks to print the exception(find what exception the system throw).

try { value = 25; }

catch(Exception) { Console.WriteLine("The Value is out of range.") }

Solution: here you check if the variable is smaller than 0 OR  bigger 20 it will throw exception. when it not trigring the condition it will display message.

try { if (value < 0 || value > 20) { throw new System.Exception(); } } catch() { Console.WriteLine("The Value is out of range.") }

For a better explicit answer leave a snapshout of your work book.
