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

Description

SortedSet: You have many elements you need to store, and you want to store them in a sorted order and also eliminate all duplicates from the data structure. The SortedSet type, which is part of the System.Collections.Generic namespace in the C# language and .NET Framework, provides this functionality.

According to MSDN Compare method returns

• Less than zero if x is less than y.
• Zero if x equals y.
• Greater than zero if x is greater than y.

Update

If your Bla class implements IComparable and you want your list sorted you can do this.

var blahs = new List {new Blah(1), new Blah(2), 
                            new Blah(3), new Blah(2)};
blahs.Sort();

If your Bla class NOT implements IComparable and you want your list sorted you can use Linq (System.Linq namespace) for that.

blahs = blahs.OrderBy(x => x.MyProperty).ToList();
