Move Instance Method refactoring

ReSharper | Refactor | Move…

This refactoring allows you to move an instance (non-static) method to another type. In contrast to moving static members, instance method cannot be moved to just any type. The list of potential target types includes types of the method parameters and types of fields in the current type. If the method uses other class members, the refactoring will pass the source class as a parameter. It will also change access rights of non-public members and encapsulate fields into public properties, if necessary. All usages of the method are updated automatically.

This refactoring may be helpful if you see that the logic of a method fits better into another type, which is passed as the method parameter or a field.

In the example below, we apply the refactoring to the LogDrawing instance method to move it to the Logger class. The private pivot field, which is used in the method is automatically encapsulated into the corresponding property:

Before refactoringAfter refactoring
class Shape { private Point pivot; private void LogDrawing(Logger logger) { var msg = String.Format("The new shape is drawn at {0}, {1}", pivot.X, pivot.Y); logger.Log(msg); } } class Logger { public void Log(string msg) { // log the message } }
class Shape { private Point pivot; public Point Pivot { set { pivot = value; } get { return pivot; } } } class Logger { public void Log(string msg) { // log the message } private void LogDrawing(Shape shape) { var msg = String.Format("The new shape is drawn at {0}, {1}", shape.Pivot.X, shape.Pivot.Y); Log(msg); } }

To move an instance method

  1. Place the caret at the declaration or a usage of an instance method in the editor, or select it in the File Structure window.
  2. Do one of the following:
    • Press F6.
    • Press Ctrl+Shift+R and then choose Move Instance Method
    • Right-click and choose Refactor | Move Instance Method in the context menu.
    • Choose ReSharper | Refactor | Move… in the main menu.
    The Move Instance Method dialog will open.
  3. Select the destination type.
  4. Optionally, change the access modifier.
  5. To apply the refactoring, click Next.
  6. If no conflicts are found, ReSharper performs the refactoring immediately. Otherwise, it prompts you to resolve conflicts.
