Use Indexer In C# Language

Indexer is similar to a property, which is allows an object to be indexed like an array. If you define an indexer for a class, then this class behaves like a virtual array, and you can access the object of this class using the array operator. Indexer are not defined with names, but you can use this keyword, which refers to the object instance . Show in Example.

Example

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace use_indexer_in_c_sharp

{

class use_Index // create class

{

private string[] List = new string[size]; //define member

static public int size = 8;

public use_Index() //create constructor

{

for (int a = 0; a < size; a++) // provide value of list

List[a] = "Not Available";

}

public string this[int index] // define index property

{

get

{

string var;

if (index >= 0 && index <= size - 1)

{
