What is operator overloading in C#?

What is operator overloading in C#?

Operator overloading allows you to define custom behavior for operators (like +, -, etc.) for your own classes.

Can you give me an example of how to overload the + operator?

Sure! Here's a simple example:

public class Point {
    public int X { get; set; }
    public int Y { get; set; }

    public static Point operator +(Point a, Point b) {
        return new Point { X = a.X + b.X, Y = a.Y + b.Y };
    }
}

This allows you to add two Point objects together.

What happens if I try to add two different types?

If you try to add two different types without an overloaded operator, you'll get a compile-time error. You need to define how those types interact.

Are there any limitations to operator overloading?

Yes, there are some limitations. For example, you cannot overload certain operators like . (member access) or :: (scope resolution).
