With the risk of sounding mean, you should read the C# reference 🙂

C# divides things into reference types and value types. Reference types are as you can imagine, being passed by reference. This means a reference to the object is passed.

Here is a contrived example of return by reference:

class MyClass // <- Reference type.
{
   private MyClass _child = new MyClass();

   public MyClass GetChild()
   {
      return _child;
   }
}

Value types are passed by value; although I imagine under the hood something else could be going on. This is not important to you though, only the behaviour is important.

Example of value types: int, char, Color…

You create a reference type through class, and a value type through struct.
