SortedList Collection in C#

SortedList (in the System.Collections namespace) is a dictionary that consists of key/value pairs. Both the key and the value can be any object. SortedList is sorted automatically by the key.

Example:
In any order you insert the data into collection , SortedList collection reorders the data internally.

SortedList sl = new SortedList();
sl.Add("C", "Cat");
sl.Add("A", "Apple");
sl.Add("B", "Ball");

// Populate the data
foreach (DictionaryEntry de in sl)
   Console.WriteLine(de.Value);     // Outputs A B C
