Making Auto-Properties Get-Only
Starting from C# 6.0, you can define get-only auto-properties, which (similarly to readonly fields) can be only initialized via a constructor or an initializer. ReSharper detects and helps you remove the redundant
set accessor on auto-properties that are initialized from the constructor/initializer and have no write usages.
If you do not want ReSharper to suggest you this, you can disable the code inspection that detects it (Auto-property can be made get-only).
The reverse functionality is also available. If you decide to change the value of a get-only property later in your code (which leads to a compiler error), ReSharper detects the error and suggests fixing it by adding the setter for the property:
Another option to make auto-properties get-only in a bulk mode is code cleanup. You can either run code cleanup with the default profile Default: Full Cleanup or run the cleanup with a custom profile solely targeted at your specific task as described below.
To remove setters from auto-properties that only have read access
- Open the Code Cleanup options: .
- Create a new profile as described in the Configuring Code Cleanup section. In the Selected profile settings section for the new profile tick the Make auto-property get-only, if possible check box.
- Click Save to apply the modifications and let ReSharper choose where to save them, or save the modifications to a specific settings layer using the Save To drop-down list. For more information, see Managing and Sharing ReSharper Settings.
- Select the scope where you want to make auto-properties get-only:
- Do one of the following:
- In the Code Cleanup dialog that opens, select the newly created profile in the Available Profiles area.
- Click Run. ReSharper will make auto-properties get-only in the selected scope.
If you want to make auto-properties get-only without opening the Code Cleanup dialog, you can bind the created profile to the silent cleanup and run it simply by pressing Ctrl+Shift+Alt+F. You can also create a custom cleanup profile that would combine making properties get-only with other code style tasks.
