What is the best way to implement this composite GetHashCode()

Question

I have a simple class:

public class TileName {
    int Zoom, X, Y;

    public override bool Equals (object obj)
    {
        var o = obj as TileName;
              


        

Answer 1

I've actually found this to be really effective.

public override int GetHashCode ()
{
    return Zoom.GetHashCode() ^ X.GetHashCode() ^ Y.GetHashCode();
}
