C# SortedSet and equality

Question

I am a bit puzzled about the behaviour of SortedSet, see following example:

public class Blah
{
    public double Value { get; private set; }

    public Bla         


        

Answer 1

You can't find the other Blah(2) because you're using a Set.

Set - A collection of well defined and **distinct** objects

MultiSet, for instance, allows duplicate objects.
