C# function input / return result

Question

hey
I'm trying to write a code that adds all the numbers between begin and end to the variable x (begin: 5 | end: 10 | 5 + 6 + 7 + 8 + 9 + 10).
can someone please explain to me how I solve such problems generally best without getting help from the community every time?

I missed the C # course on this topic while studying and can't find it anymore.

Answer 1

Please reread
C# objects, you either need to create an object or your function should be static.(same mistake you made by temperatur)

And reread for loop. The three parts of the for-loop. All have their own purpose.
initialisation, condition, iteration

Answer 2

Your function should be static.
