Refactorings
Last modified: 08 September 2023
ReSharper provides an extensive set of automated solution-wide code refactorings that allow you to rename, move, and safely delete symbols; introduce and inline fields, variables, or parameters, and carry out many more transformations painlessly.
tip
In addition to refactorings, ReSharper provides a number of smaller local code transformations available with context actions.
Refactorings are available for most of the supported languages and project items. For more information about specific refactorings, study the following sections:
Place the caret at a symbol, select a code fragment that you want to refactor, or select an item in a tool window.
Do one of the following:
In the main menu, choose ReSharper | Refactor, and then select a desired refactoring. The list of refactorings available in this menu depends on the current context. If ReSharper cannot suggest any refactorings for the context, the entire menu is disabled.
In the editor, File Structure window, or other ReSharper window, right-click the item you want to transform, choose Refactor from the context menu, and then select the required refactoring.
In the main menu, choose ReSharper | Refactor | Refactor This, or press CtrlShift0R to display the list of applicable refactorings, then select one of them. You can also choose Refactor This in the context menu of a selection.
If the selected refactoring requires user input, the refactoring wizard opens. Note that the wizard's dialogs are not modal, so you can edit the code while the wizard is open.
To roll back refactoring actions, the wizard provides the option To enable Undo, open all files with changes for editing. If you select this option, ReSharper opens all modified files in new editor tabs and enables you to roll the refactoring back. In this case, you will need to save the changes yourself. If this option is not selected, ReSharper saves modified files automatically, without opening them.
If a refactoring operation would cause code conflicts (such as duplicate names, visibility conflicts, and so on), the wizard displays the list of conflicts on the last step, before you apply the refactoring. For some conflicts, the wizard can also suggest quick-fixes. For more information, refer to Resolve conflicts in refactorings.
note
Visual Studio provides its own Refactor menu, which is available from both main and context menus. By default, ReSharper hides the native Visual Studio menu replacing it with its own one. To make the Visual Studio menu accessible, select the Hide overridden Visual Studio menu items checkbox on the Environment | Editor | Visual Studio Features page of ReSharper options.
Some refactorings are available immediately after you modify code in the editor. For more information, refer to Inplace refactorings
Most of ReSharper's refactorings are available in C# and Visual Basic, some are available in several languages, others are language-specific. The table below lists all refactorings and languages/technologies where they are supported.
The instructions and examples given in the topics within this section address the use of refactorings in C#. For more information about refactorings available for specific languages, refer to the corresponding topics in the ReSharper by language section.
