Purpose

Removes an empty constructor, if it has no parameters and there are no other constructors in the class. When the class does not contain a constructor, the default one is created internally. The default constructor instantiates the object and sets member variables to the default values as listed in Default Values Table.

Availability

Available when the cursor is on a constructor declaration, provided that the constructor is empty and does not contain parameters. Also, the class should contain no other constructors.

Usage

1. Place the caret on an empty constructor declaration.

   Note

   The blinking cursor shows the caret’s position at which the Refactoring is available.

   C#

   public class Person {
       public│ Person() { }
       private int id;
       public string Name { get; set; }
   }
   

   VB.NET

   Public Class Person
       Public│ Sub New()
       End Sub
       Private id As Integer
       Public Property Name() As String
   End Class
   

2. Press the Ctrl + . or Ctrl + ~ shortcut to invoke the Code Actions menu.
3. Select Remove Redundant Constructor from the menu.

After execution, the Refactoring removes the constructor.

C#

public class Person {
    private int id;
    public string Name { get; set; }
}

VB.NET

Public Class Person
    Private id As Integer
    Public Property Name() As String
End Class
