Hi I'm very new at programming and currently learning C# so please bare with me. I'm currently stuck trying to display an "index does not exist" for the user.Tried different methods but I kept getting errors. I've looked around but could not find something similar to what I'm doing. Here is my current code:

```
        int[] myNumbers = { 10, 5, 15, 20, 30 };
        Console.WriteLine("User please enter a number from 0 to 4\n");

        int userIndex = Convert.ToInt32(Console.ReadLine());
        Console.WriteLine("You chose number: " + myNumbers[userIndex]);

        if (userIndex > 4)
        {
            Console.WriteLine("Index does not exist " + myNumbers[userIndex);
        }

        Console.ReadLine();

```

Thank you.
