C# Class Method - Properties

Hello there,

I need some help for the following code that;

public bool OnMap (Point point)
        {
        bool inBounds = 
            point.X >= 0 && point.X < Width 
            point.Y >= 0 && point.Y < Height;

        return inBounds;
        }

So, we created a Point point property inside OnMap method. Point is the custom type that refers to Point.cs (or Point Class) the point with lower case is its name. Inside the method we used point.X and it's simply refers to the X,Y variables from the Point Class, however X is also the name of the variable and it seems there are two names next to each other. Why do not we use Point.X and Point.Y with uppercase letters?

:point_right: The argument's name is "point" (with lower-case "p")

So if you want to refer to a property inside it, you preface the property with the name, like "point.X".

A capital "P" would refer to the class itself, and would only be used to prefix static variables of the class. Since these properties are instance elements, they can only be accessed through a class instance such as the function argument.
