Code Cleanup allows you to apply Refactorings and Code Formatters to a document. During Code Cleanup, CodeRush analyzes code in the active file and applies certain Refactorings and Code Formatters where needed. This feature is helpful when you need to refactor a large amount of code.
The following is a list of possible Cleanup Refactorings when performing Code Cleanup:
The hyperlinked Code Actions are available separately.
|Add copyright header||Adds a copyright comment at the file's beginning (configuration)|
|Apply 'Attribute lists' style||Combines several attributes into a single list or breaks attribute lists apart (according to the corresponding style rule)|
|Apply 'Attribute lists' style to assembly-level attributes||Combines several assembly-level attributes into a single list or breaks attribute lists apart (according to the corresponding style rule)|
|Apply 'Braces in statements' style||Adds or removes optional block delimiters to/from all single-statement blocks (according to the corresponding style rule)|
|Apply built-in type style||Converts explicitly-typed variable declarations to implicit or vice versa (according to corresponding style rule). The related Code Action is Make Implicit/Explicit|
|Apply 'Optional parenthesis' style||Adds or removes optional parenthesis to/from the selected code elements (according to the corresponding style rule)|
|Apply variable declaration style||Converts the CLR types to their keyword aliases or vice versa (according to corresponding style rule)|
|Apply visibility style||Adds visibility modifiers where required or removes them where possible (according to corresponding style rule)|
|Apply 'this' qualifier style||Adds 'this' qualifier where required or removes it where possible (according to corresponding style rule)|
|Collapse property accessors||Converts all property accessors into a single-line form|
|Convert to String Interpolation||Converts all formatted strings into the string interpolations|
|Convert to string.Empty||Converts all empty string literals ("") into the string.Empty system constant|
|Expand property accessors||Converts all property accessors into a multi-line form|
|Format document||Executes the Document Formatting (C#) feature|
|Make properties auto-implemented||Converts all properties with fully described accessors to auto-implemented properties|
|Organize members||Sorts member declarations in the class and removes the redundant line breaks|
|Remove all comments, excluding XML comments||Cleans the code from the non-XML comments|
|Remove all regions||Cleans the code from the #region preprocessor directives|
|Remove redundant braces in blocks without parent statement||Deletes optional block delimiters in "floating" code blocks|
|Remove redundant type cast||Deletes the type casts in the places where they can be omitted|
|Remove redundant type qualifiers||Deletes the type qualifiers in the places where they can be omitted and adds the required using/Imports statements|
|Remove redundant 'base' qualifier||Deletes the 'base' qualifier in all member references where it can be omitted|
|Remove unused members||Deletes the unused members|
|Remove unused namespace references||Deletes the unused namespace references|
|Remove unused parameters||Deletes the unused method parameters.|
|Remove unused types||Deletes "internal", "private" and "private protected" nested types, and "internal" regular types|
|Remove unused private types||Deletes unused private nested types|
|Remove unused variables||Deletes the unused variables|
|Sort modifiers||Sorts member modifiers according to corresponding style rule|
|Sort namespace references||Sorts namespace references alphabetically or by length|
|Use 'nameof'||Converts all string literals containing a variable or class member name to the nameof expression with the corresponding variable/member as an argument|
|Use expression bodies||Converts all single-statement property and methods into expression-bodied structures|
You can configure what Code Actions are executed during Code Cleanup. Open the Editor | <Language> | Code Cleanup options page and tick the required Code Actions to enable them. Click OK when you are finished.
The Cleanup Refactorings order in the options window defines their execution order.
Follow the steps below to execute Code Cleanup in an open file:
Alternatively, you can use the following methods to execute Code Cleanup:
CodeRush provides the "Apply Code Cleanup when saving a document" option, you can automatically clean up a file before it is saved.
CodeRush does not clean up a file when you close the unsaved file or solution.
Follow the steps below to execute Code Cleanup in a project:
When you cancel the process, the code remains unchanged.
Use Visual Studio's Undo action (Edit | Undo menu item) if you need to undo the cleanup after its completion. Note that this action is available when a document is open.
This feature is in a preview state because code cleanup can change your code's behavior or make it invalid. If this happens, undo the operation as described above.
