How do I compare two structs for equality in C#?

In C#, you can compare two structs for equality by overriding the Equals method and the == operator.

Can you show me an example of how to override Equals?

Sure! Here's a simple example:

public struct Point
{
    public int X;
    public int Y;

    public override bool Equals(object obj)
    {
        if (obj is Point)
        {
            Point p = (Point)obj;
            return X == p.X && Y == p.Y;
        }
        return false;
    }
}

What about the == operator? How do I override that?

You can override the == operator like this:

public static bool operator ==(Point a, Point b)
{
    return a.Equals(b);
}

public static bool operator !=(Point a, Point b)
{
    return !(a == b);
}

Is it necessary to override GetHashCode as well?

Yes, it's a good practice to override GetHashCode whenever you override Equals to maintain consistency.
