Refactoring in visual studio 2013,2015

Refactoring, change the internal structure of the code without any changes in behavior/outer structure. By using visual studio plugins, you can do the following refactoring in the visual studio code. The most popular and powerful refactoring plugin/extension in visual studio is visual assist. By using it, we can do some following tasks:

  • Extract method refactoring: By using visual studio we can create new methods for existing code, I want to say that if you have a code in a method, you want to break it in different segments/methods then you can use extract method like Suppose your code look like
   public class Class1  
   {  
     public void display()  
     {  
       int a=10;  
       int b=20;  
       Console.WriteLine(a + b);  
     }  
   }  

Select the code fragment you want to extract:

  int a=10;  
       int b=20;   

Right click on selected text, Refactor--> Extract Method..., appear new window.

After pressing the "ok" button, your code look like

  public class Class1  
   {  
     public void display()  
     {  
       int a;  
       int b;  
       NewMethod(out a, out b);  
       Console.WriteLine(Convert.ToString(a+b));  
     }  
     private static void NewMethod(out int a, out int b)  
     {  
       a = 10;  
       b = 20;  
     }  
   }  

  • Change class name also the file name: If you want to change class name after creating code then you can do this by replacing. But, file name doesn't change. So, try visual assist to change the class name, constructor name, and file name.    
Right click on class name, select Refactor(VA)--Rename to change the class name also file name.


After do this, your code and file:

Change class name also the file name

wpf listview bind with list of string type

As we all know the wpf listview is inherited class of listbox and have almost all the properties of listbox. We have learnt listbox binding with string list in our earlier post. In this article we bind the listview with the same string list.

Just place a wpf listview having only name property, because we have to access that wpf listview in our code behind file. We can also use height and width property of the listview, if the data items are of lengthy string.
<ListView>
<ListView.Name>listView</ListView.Name>
</ListView>

Now use the same list of string as in previous post i.e.
List<string> strList = new List<string>();
strList.Add("London");
strList.Add("Italy");
strList.Add("California");
strList.Add("France");
listView.ItemsSource = strList;

Now look out the last statement, it will set the item source of the wpf listview as this string list. When we run the project it will show a listview with four items:

To get selected item the same procedure will follow as in listview bind with grid resource.
