Lokee: Extension Methods

Extension Methods

Posted On Sunday, November 14, 2010 at at 5:06 AM by Lokesh

I was working on a Ruby on Rails project. I was partly influenced by the syntactic sugars.

Here is the extension method in C# for Ruby times

   1:  using System;

2:

   3:  namespace ConsoleApplication1

   4:  {

   5:      class Program

   6:      {

   7:          static void Main(string[] args)

   8:          {

   9:              5.Times(DoSomething);

  10:          }

11:

  12:          private static void DoSomething(int x)

  13:          {

  14:              // Do something with x

  15:          }

  16:      }

17:

  18:      internal static class Extensions

  19:      {

  20:          public static void Times(this int times, Action<int> action)

  21:          {

  22:              for (var i = 0; i < times; i++)

  23:                  action(i);

  24:          }

  25:      }

  26:  }
