How to define the operator ==

Question

Given the class as follows,

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

How to define an overload operato

Answer 1

Here is a short example of how to do it, but I very strongly recommend reading Guidelines for Overloading Equals() and Operator == (C# Programming Guide) to understand the interaction between Equals() and == and so on.

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

  public static bool operator ==(Number  a, Number b)
  {
    // TODO
  }
}
