JetBrains Rider 2022.1 Help

Remove code redundancies

On the Editor | Inspection Severity page of JetBrains Rider settings Ctrl+Alt+S, in the Redundancies in Code categories of different languages, JetBrains Rider lists a lot of code redundancies that have associated code inspections. For most of these redundancies, JetBrains Rider provides quick-fixes. Some code redundancies cannot be fixed automatically, and quick-fixes for them are performed in the interactive mode, requiring the user input. But the majority of the redundancies can be fixed without user interaction, using either fix in scope or code cleanup.

From any code redundancy highlighted by the design-time code inspection, you can invoke the 'Remove redundant code' quick-fix that will remove the current redundancy as well as all redundant code in the file, project or solution:

Remove redundant code quick-fix

Another option to remove code redundancies in a bulk mode is code cleanup. You can either run code cleanup with the Built-in: Full Cleanup profile or create and run a custom profile solely targeted at your specific task as described below.

Remove code redundancies with custom Code Cleanup profile

  1. Press Ctrl+Alt+S or choose File | Settings (Windows and Linux) or JetBrains Rider | Preferences (macOS) from the menu .

  2. Go to the cleanup profiles settings page: Editor | Code Cleanup.

  3. Create a new profile as described in the Create a new custom cleanup profile section. In the Selected profile settings section for the new profile, tick the Remove code redundancies checkbox. Optionally, you can enable other code cleanup tasks in this profile.

  4. Click Save in the Settings dialog to apply the modifications and let JetBrains Rider choose where to save them, or save the modifications to a specific settings layer using the Save To list. For more information, see layer-based settings.

  5. Select the scope where you want to remove code redundancies:

    • Set the caret anywhere in the file to remove code redundancies to the file.

    • Select one or more items in the Solution Explorer to remove code redundancies in the files under these nodes and their child items.

  6. Press Ctrl+E, C or choose Code | Reformat and Cleanup… from the main menu .

  7. In the Reformat and Cleanup Code dialog that opens, select the newly created profile and choose another scope if needed. .

  8. Click OK. JetBrains Rider will remove code redundancies in the selected scope.

If you want to remove code redundancies without opening the Code Cleanup dialog to choose a profile, you can bind the created profile to the silent cleanup and run it by pressing Ctrl+E, F. You can also create a custom cleanup profile that would combine removing code redundancies with other code style tasks.

You can remove code redundancies in code that you have recently modified and are going to commit to Git. JetBrains Rider will run the selected cleanup profile before committing.

Clean up code before committing it to Git

  1. Press Ctrl+K or select Git | Commit from the main menu.

  2. In the Commit tool window, click Show Commit Options and in the Before Commit area, select the Cleanup with... checkbox.

  3. Click Choose profile and choose your custom Code Cleanup profile.

  4. Click Commit or Commit and Push. JetBrains Rider will run code cleanup on the ranges staged for the commit, and then commit the changes.

You can remove code redundancies every time you save changes in a file to make sure that your edits always comply with your code style. Note that this will only happen when you save changes explicitly with Ctrl+S or Ctrl+S and will not be triggered by auto-saving. However, all auto-saved files are placed to the 'reformat and cleanup' queue and will be processed on the next explicit save.

Automatically remove code redundancies on saving changes

  1. Press Ctrl+Alt+S to open the IDE settings and select Tools | Actions on Save.

  2. Select Reformat and Cleanup Code, choose your custom Code Cleanup profile and whether to apply it to the whole file or only to the changed lines.

  3. The next time you finish editing and save the file or all files , JetBrains Rider will clean up the affected files using the selected profile.
