Built-In Type References Style

The C# type keywords and .NET Framework type names are interchangeable for built-in C# types. If you prefer to stick to one or another style for built-in type names, ReSharper can help you maintain your preference.

ReSharper helps you enforce preferences for C# built-in types in the existing code and takes your preferences into account when it produces new code with code completion and code generation features, applies code templates and performs refactorings.

In this topic:

Enforcing preferences for C# built-in types

ReSharper checks all built-in type references for compliance with your preferences and if they do not comply it highlights such references and suggests the corresponding quick-fix or fix in scope. Default ReSharper's preferences say that the C# keyword is preferred.

Built-in type usage style quick-fix

If you change your preference, ReSharper will help you use .NET Framework type names:

Built-in type usage style quick-fix

Another option to enforce preferences for C# built-in types 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 apply preferences for C# built-in types with code cleanup

  1. Open the Code Cleanup options: ReSharper | Options | Code Editing | Code Cleanup.
  2. Create a new profile as described in the Configuring Code Cleanup section. In the Selected profile settings section for the new profile tick the Fix built-in type references check box.
  3. 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.
  4. Select the scope where you want to enforce your preferences:
    • Set the caret anywhere in the file to enforce your preferences to the file.
    • Select one or more items in the Solution Explorer to enforce your preferences in the files under these nodes and their child items.
  5. Do one of the following:
    • Press Ctrl+Alt+F or choose ReSharper | Edit | Cleanup Code in the main menu .
    • Right-click anywhere in the text editor or right-click the selection and choose Cleanup Code in the context menu.
  6. In the Code Cleanup dialog box that opens, select the newly created profile in the Available Profiles area.
  7. Click Run. ReSharper will enforce your preferences in the selected scope.

If you want to enforce preferences for C# built-in types without opening the Code Cleanup dialog box, 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 applying the preferences with other code style tasks.

Configuring preferences for referencing C# built-in type

Your built-in type naming preferences are saved using the mechanism of shared settings. Among other things, this mechanism allows you to maintain different preferences for different solutions as well as to keep these preferences under a VCS and automatically share them with your team members.

To configure preferences for C# built-in types

  1. Go to ReSharper | Options | Code Editing | C# | Code Style.
  2. Modify settings in the Built-in type naming category according to your coding practices/standards.
  3. The Notify with selectors in the right column allow you to set severity levels of code inspections detecting code that differs from your preferences.
  4. If you do not want ReSharper to check and enforce some preferences and to prevent code cleanup from enforcing selected preferences, you can disable them by setting their severity levels to Do not show.
  5. 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.

You can also change your preference of referencing C# built-in types right in the editor, where a corresponding issue is highlighted:

To change preference of referencing C# built-in types from the editor

  1. Set the caret to a code issue highlighted by a ReSharper's inspection.
  2. Press Alt+Enter or click on the action indicator to the left of the caret to open the action list.
  3. In the action list, choose Inspection "Replace built-in type reference..." | Configure code style and then select a desired preference:
    Changing code style preference for referencing C# built-in types
  4. Your change will be saved using the smart save logic.
  5. If you need to save the modified style preference in a shared settings layer, click on the Configure code style menu item or press Enter when it is selected. ReSharper will open the Code Editing | C# | Code Style options page where you can modify your preference as needed, click Save To and then choose the desired settings layer.
