Hi Shah
Indexers allows you to access the object like you are accessing the array .
Indexers permit instances of a class or struct to be indexed in the same way as arrays. Indexers are similar to properties except that their accessors take parameters

<br />
class SampleCollection<T><br />
{<br />
    private T[] arr = new T[100];<br />
    public T this[int i]<br />
    {<br />
        get<br />
        {<br />
            return arr[i];<br />
        }<br />
        set<br />
        {<br />
            arr[i] = value;<br />
        }<br />
    }<br />
}<br />
<br />
// This class shows how client code uses the indexer<br />
class Program<br />
{<br />
    static void Main(string[] args)<br />
    {<br />
        SampleCollection<string> stringCollection = new SampleCollection<string>();<br />
        stringCollection[0] = "Hello, World";<br />
        System.Console.WriteLine(stringCollection[0]);<br />
    }<br />
}<br />
<br />
<br />


Indexers enable objects to be indexed in a similar way to arrays.

A get accessor returns a value. A set accessor assigns a value.

The this keyword is used to define the indexers.

The value keyword is used to define the value being assigned by the set indexer.

Indexers do not have to be indexed by an integer value; it is up to you how to define the specific look-up mechanism.

Indexers can be overloaded.

Indexers can have more than one formal parameter, for example, when accessing a two-dimensional array.


Thanks and Regards
