Cleanup your code - remove unused using statements

by Edward 20 October 2009 06:12

One of the annoying things I have been dealing with in Visual Studio 2008 and Framework 3.5, is the unnecessary "using" statements the IDE adds, when you add a new webpage to your project.

Visual Studio does give you the option to remove these unused using statements, but they do not "tell" you about it.

Here is a quick way of removing unused using statements.

From the Context Menu:

  1. 1) Right-click anywhere inside the code editor,
  2. 2) point to Organize Usings,
  3. 3) now click Remove Unused Usings.


Here is an example:


Before:

   1:  using System;
   2:  using System.Linq;
   3:  using System.Collections.Generic;
   4:  using System.Text;
   5:  using System;
   6:   
   7:  namespace ConsoleApplication1
   8:  {
   9:      class Program
  10:      {
  11:          static void Main(string[] args)
  12:          {
  13:              Console.WriteLine("DasCode.Net test page, removing 
unused using statements"
);
  14:          }
  15:      }
  16:  }


After:

   1:  using System;
   2:   
   3:  namespace ConsoleApplication1
   4:  {
   5:      class Program
   6:      {
   7:          static void Main(string[] args)
   8:          {
   9:              Console.WriteLine("DasCode.Net test page, removing 
unused using statements"
);
  10:          }
  11:      }
  12:  }
