To perform a refactoring
- Set your 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 , and then select a desired refactoring. The list of refactorings available in this menu depends on the current context. If ReSharper cannot suggest any refacrotings 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 , or press Ctrl+Shift+R to display the list of applicable refactorings, and select one of them. You can also choose Refactor This in the context menu of a selection.
- Use default keyboard shortcuts assigned to specific refactorings, or assign custom shortcuts to your favorite refactorings.
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, etc.), 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, see Resolving Conflicts in Refactorings.
Some refactorings are available immediately after you modify code in the editor. For more information, see Inplace Refactorings
This refactoring allows you to create a new local variable or constant based on a selected expression, initialize it with the expression, and finally replace all occurrences of the expression in the method with references to the newly introduced variable.
You can also invoke this refactoring with the dedicated shortcut Ctrl+Alt+V.
In the example below, we use this refactoring to replace two occurrences of the same string with a variable:
Introduce Variable for Substring
This refactoring helps you quickly move a part of a string to a separate variable.
If the ECMAScript 6 is selected as a language level in ReSharper settings, the refactoring will add a new template argument for the extracted substring. If the language level is ECMAScript5, then string concatenation is used:
|Before refactoring||After refactoring (ECMAScript 6)||After refactoring (ECMAScript 5)|
This refactoring allows you to replace all occurrences of a variable in the code with its initializer. Note that the refactoring should be only applied if the variable value stays unchanged after initialization.
You can also invoke this refactoring with the dedicated shortcut Ctrl+Alt+N.
In the example below, we use this refactoring to inline the
|Before refactoring||After refactoring|
Move to Resource
You can also invoke this refactoring with the dedicated shortcut F6.
This refactoring allows you to change name of any symbol defined in your solution. All references to and usages of the symbol are updated automatically.
You can also invoke this refactoring with the dedicated shortcut F2.
