Create methods from code snippets in Visual Studio .NET

In this section we will see a very interesting and useful trick of visual studio called the extract method.

Visual studio tip 2: Create methods from code snippets:-

In this section we will see a very interesting and useful trick of visual studio called as the extract method.  Below are two lines of code which help us to display the current year of the system.  We expect that we would need to display the current year from different parts of program.

static void Main(string[] args)
{
   int CurrentYear  = DateTime.Now.Year;
   Console.WriteLine(CurrentYear.ToString());
}

So as a good practice we would like to wrap these 2 lines of code in to a method so that we can call it again and again in other sections of the code and thus increase reusability and reduce redudancy.

One way of doing the same is by creating a method manually and then moving those two lines code  of in to the method.

For such kind of scenario visual studio has provided  a nice facility for automation called as extract method. Select the lines of code which you want to move to a method , right click and then click on extract method as shown in the below image.



Once you click on extract method you will be asked to input the method name as shown in  the below image.



Once you put the method name and click ok , you should see those two lines of code are moved in to a separate method and the method name is invoked in static void main as shown in the below code snippet.  All automated LOL.

static void Main(string[] args)
{
             DisplayCurrentYear();
}

private static void DisplayCurrentYear()
{
   int CurrentYear = DateTime.Now.Year;
   Console.WriteLine(CurrentYear.ToString());
}
