Indexer Myth

Hi,

 

This is about how you create ‘Indexer’ in a class.

Indexer implementation provide birth to ‘Parametrized’ and ‘Default’ property concept.

 

class ColorManager     {         Hashtable colorsTable = new Hashtable();                 public Color this[string name] // Indexer         {             get             {                 return colorsTable [name] as Color;             }             set             {                 colorsTable.Add(name, value);             }         }     }

class Color     {         private int red;         private int green;         private int blue;           // Constructor         public Color(int red, int green, int blue)         {             this.red = red;             this.green = green;             this.blue = blue;         }            }

 

static void Main()

{

    ColorManager colormanager = new ColorManager();

 

    colormanager["red"] = new Color(255, 0, 0);

    colormanager["green"] = new Color(0, 255, 0);

    colormanager["blue"] = new Color(0, 0, 255);

}
