Hello everybody I'm Nick and in this video I am going to explain to you exactly what the ref keyword does in C#. I will explain this in the context of parameter passing because it is where you will most commonly encounter it but I will also talk about ref structs and how you can use it there to prevent something from being allocated in a place where it shouldn't.
