SortedList Class

Part of my 2008 study notes for exam 70-536 (.NET Framework 2.0).

Overview

Key-value pair based collection.
Contains DictionaryEntry objects.
Accessible by index and key.
Sorts items when they are added.

Good practice

When possible, use a generic collection instead of the object-based SortedList.

Examples

Adding and Removing Elements

SortedList a = new SortedList();
a.Add("Key2", "Hello");
a.Add("Key1", "World");
a.Add("Key0", "Start");
 
Console.WriteLine(a["Key1"] + " " + a["Key2"]);
Console.WriteLine();
foreach (DictionaryEntry d in a) { Console.WriteLine(d.Value); }
Console.WriteLine();
foreach (object v in a.Values) { Console.WriteLine(v); }
Console.WriteLine();
a.Remove("Key1");
foreach (object k in a.Keys) { Console.WriteLine(a[k]); }
