Unhandled exception. System.IndexOutOfRangeException: Index was outside the bounds of the array.

Good morning, I’m sorry to disturb you but I have a slight problem with my code. Here, when I try to run my code, I get the following message. However, I have no idea what I need to correct; I tried several things, in doubt, I checked well if I converted everything from "string" to "int", but nothing to do, I still have the same error. I would very much like to have some help so that we can fix this. Thank you in advance....
