First time posting here. Well. I’m trying to make a program that can makes you delete a student and add and so forth. But when i delete and i add it again and then i delete it again I have this error message. ‘Unhandled exception. System.IndexOutOfRangeException: Index is out of range.’

Here’s the code.

Students.CS
`using System;

if someone can help me please say so! I’d be paying much attetion here, thanks and have a blessed day.

I tried rewriting the code, adding more methods to check the index and so on, didn’t work. I also tried GPT, nothing worked
