Reverse Sorted Dictionary in .NET

Question

Is there any way I can iterate backwards (in reverse) through a SortedDictionary in c#?

Or is there a way to define the SortedDictionary in descending order to begin

Answer 1

If you're using .NET 3.5, you can use the OrderByDescending extension method:

        var dictionary = new SortedDictionary();
        dictionary.Add(1, "One");
        dictionary.Add(3, "Three");
        dictionary.Add(2, "Two");
        dictionary.Add(4, "Four");



        var q = dictionary.OrderByDescending(kvp => kvp.Key);
        foreach (var item in q)
        {
            Console.WriteLine(item.Key + " , " + item.Value);
        }
