C# C# Objects Methods Overloading Methods

question regarding the first overload example shown

public int DistanceTo(Point point) { return DistanceTo(point.X, point.Y); } In this example of overloading why do we have to specify return (point.X, point.Y); I tried running it written as return DistanceTo(point); and it doesn't work. I thought it would be implicit that a point object has an X and Y as set up in the fields. I understand that the new overload method allows for this type of call Console.WriteLine(point.DistanceTo(pointTwo)); just would not have thought to write the method this way if It had been presented in an objective. Thank you for your time.

The overloaded version that takes a single "Point" argument is calling the other version (the one that uses two coordinates) to compute the distance.

If you change the return to call "return DistanceTo(point)" instead, that makes it call itself which would cause an infinite recursion loop.
