What parts of C# should i learn for unity?

Question

i want to make unity games which requires C# but i noticed a lot of things that doesn't seem useful for unity so i just wanted to know do i need to know C# completely or just the basics

Answer 1

I've been using unity for 2 years already. I started game developing without having a lot of programming knowledge. I've started working on several game projects, and step by step I learnt a lot about C#. At the moment i am a 2nd year Computer Science student and I already published some games on Google Play Store.
Learn by practicing. Just keep working and eventually, if you really like it you'll end up learning c# and the basics of programming really fast.

Answer 2

i start unity even without writing a single code in c# before..so, if u have programming knowledge(in any language), u can start right away..sure, its better if u know c# and game programming first in general, but u can learn it while making game
