Override equals to compare objects in C#

If A and B are two different objects in memory, but they are of the same type and have all the same values... are they equal?

It's a deep question, but if, for your problem domain, the answer is "YES" then you can embed this answer in your code as follows:

public class MyThing
	public string ID { get; set; }
	public decimal? Hats { get; set; }
	public decimal? Noses { get; set; }

	public override bool Equals(object obj)
		var test = obj as Mything;
			test != null &&
			ID == test.ID &&
			Hats == test.Hats &&
			Noses == test.Noses;
