Reverse .NET SortedList

 This post shows how you could reverse a SortedList in C# by its keys:

SortedList<string, string> strlist = new SortedList<string, string>();

strlist.Add("f3", "xxx");

strlist.Add("f1", "ccc");

strlist.Add("f2", "aaa");

foreach (KeyValuePair<string, string> kvp in strlist)

{

    Console.WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value);

}           

Console.WriteLine("reverse the list");

IEnumerable<KeyValuePair<string, string>> revList = strlist.Reverse();

foreach (KeyValuePair<string, string> kvp in revList)

{

    Console.WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value);

}
