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 (var v in a.Values) { Console.WriteLine(v); }
Console.WriteLine();
a.Remove("Key1");
foreach (var k in a.Keys) { Console.WriteLine(a[k]); }
