If you’re proficient with another programming language, preferably C based (C++, JavaScript etc) then you should be able to pick up C# in a week or two.
Otherwise you’re going to have to have to put in the time and effort to learn how to program. There are no shortcuts and trying to speed through it is only going to harm you. There are various YouTube tutorials and websites like W3Schools (I think?) that can help you here. Of course there’s always msdn but I’ve found most of their examples hard to follow and overcomplicated.
And just some advice, I wouldn’t try to get into creating game hacking tools in C# (or any language for that matter) without a solid understanding of programming. Without this you are never going to be able to create your own solutions to problems and will just end up copy pasting other peoples code.
