An Indexer in C#:

C# provides a new functionality called indexers which are use for treating as an object of array. The indexers are usually known as smart array in C#. Defining an indexer is much like defining a property.

So we can say that the indexer is a member that enables an object to be indexed in the same way as an array.

Syntax of indexer in C#:

<Modifier><return type> this [argument list]

{

Get

{

// get codes goes here

}

Set

{

// set codes goes here

}

}

Where modifier can be private, public or protected etc.

And ‘this’ is this is a special keyword in C# to indicate the object of current class.

The argument list specifies the parameters list of the indexer.
