Indexers in C#

Indexers:

The indexers are usually known as smart arrays in C# community. Defining a C# indexer is much like defining properties. We can say that an indexer is a member that enables an object to be indexed in the same way as an array.

this [argument list] 

{ 

    get 

    { 

        // Get codes goes here 

    } 

    set 

    { 

        // Set codes goes here 

    } 

}

The following program shows a C# indexer in action

// C#: INDEXER 

Using System; 

Using System.Collections; 

Class MyClass 

{ 

    Private string [] data = new string [5]; 

    Public string this [int index] 

    { 

       Get 

       { 

           return data[index]; 

       } 

       set 

       { 

           data[index] = value; 

       } 

    } 

}

Class MyClient 

{ 

   Public static void Main () 

   { 

      MyClass mc = new MyClass (); 

      mc [0] = "K1"; 

      mc[1] = "A3-126"; 

      mc[2] = "A22"; 

      mc[3] = "Navi"; 

      mc[4] = "Mumbai"; 

      Console.WriteLine("{0},{1},{2},{3},{4}",mc[0],mc[1],mc[2],mc[3],mc[4]);
