SortedList example in c#.

SortedList:-

It is the combination of Arraylist and hashTable . It contains a list of items that can be accessed by using a key or an index. If you access items using an index , it is an arraylist ,and if you are accessing an item using a key , it is a hashtable. The collection of items is always sorted by the key value.

Properties Of  SortedList Class:-

Capacity :- Gets or sets the number of elements that SortedList can contain.

Count :- Gets the number of elements actually contained thr SortedList.

IsFixedSize :- Gets a value indicating whether the SortedList has fixed size.

IsReadOnly :-  Gets a value indicating whether the SortedList has ReadOnly.

Item :- Gets or sets the elements at specified index.

Key :- Gets an ICollection containing the keys in the SortedList.

Value :- Gets an ICollection containing the values in the SortedList.

Methods Of SortedList Class :-

There are various methods in SortedList class for ex. Add(), Clear(),Remove() etc. I have explained all methods in below example of sortedlist.

Example:-

using System;

using System.Collections;

using System.Linq;

using System.Text;

using System.Data;

namespace CollectionExample

{

    class Program

    {

//SortedList Example-------------------------------------------------------------------------

            Console.WriteLine("-------------SortedList table Example---------------");

            SortedList sl = new SortedList();

            sl.Add("1", "Sushil");

            sl.Add("2", "Kumar");

            sl.Add("3", "Sanjay");

            sl.Add("4", "Muthu");

            sl.Add("5", "Ashu");

            sl.Remove("1");

            if (sl.ContainsValue("Mantra"))

            {

                Console.WriteLine("This name already exist in SortedList.");

            }

            else

            {

                sl.Add("6", "Mantra");

            }

            ICollection key = sl.Keys;// to get collection of key

            foreach (string s in key)

            {

                Console.WriteLine(s + " : " + sl[s]);

            }

            Console.ReadKey();

      }

   }

}

Output:-

-------------SortedList table Example---------------

2 : Kumar
