SortedMap Interface in C#
Java has SortedMap Interface, whereas an equivalent of it in C# is SortedList.
SortedList collection in C# use a key as well as an index to access the items in a list.
A sorted list is a combination of an array and a hash table. It contains a list of items that can be accessed using a key or an index. If you access items using an index, it is an ArrayList, and if you access items using a key, it is a Hashtable. The collection of items is always sorted by the key value.
Let us see an example to work with SortedList and display the keys −
Example
using System;
using System.Collections;
namespace Demo {
class Program {
static void Main(string[] args) {
SortedList sl = new SortedList();
sl.Add("ST0", "One");
sl.Add("ST1", "Two");
sl.Add("ST2", "Three");
ICollection key = sl.Keys;
foreach(string k in key) {
Console.WriteLine(k);
}
}
}
}Output
ST0 ST1 ST2
