What I have tried:

I tried changing the code but that didn't work also if there is anything else wrong with my code don't hastate to fix it

You haven't told us what's wrong with the code. What error(s) are you encountering, what part of the code isn't working as intended?

Also your code seems to have two Main() methods which is odd, have you just copied and pasted multiple files into one big block?

i just have the error cs5001

Use Improve question to update your question.
So that everyone can pay attention to this information.

What is it supposed to do ?
describe how it don't work.

1 solution

If you don't understand a compiler error, google it: Compiler Error CS5001 | Microsoft Docs[^]
It says:
Program does not contain a static 'Main' method suitable for an entry point

Why does it throw it on your code?
Simpel: how many static Main methods do you have? If it's more than one it has no idea which one it should be calling.
And the one and only Main method needs to be inside a class as C# has no concept of "global" methods, variables, or properties.
