Find code issues with code inspection

Static code analysis in ReSharper is called Code Inspection and performed by applying over 2300 individual code inspections to your code in all supported languages.

Code issues can be found in several ways:

• ReSharper finds and highlights code issues automatically in design time for all files opened in the editor.

• The design time code inspection scope can be extended to the entire solution with the solution-wide analysis- in this case, you will be able to see all errors (and optionally warnings) in the solution as well as some additional issues in the opened files, for example unused public members.

• You can find code issues in the specified scope, which can be as large as the whole solution.

• You can also find code issues from the command line.

tip

The easiest way to deal with code issues highlighted in the editor is to set the caret at the highlighted code item and press Alt+Enter or click the action indicator that appears to the left of the code issue. The action list will pop up where ReSharper suggests one or more quick-fixes for most issues.

You can extend the default set of code inspections with structural search and replace patterns, and get more inspections for specific purposes by using ReSharper extensions.

tip

If necessary, you can disable all inspections (except those detecting compiler errors) in a specific block of code by inserting // ReSharper Disable All before and // ReSharper Restore All after it, or in a specific type or member by adding the following attribute: [SuppressMessage("ReSharper", "All")].

This feature is supported in the following languages and technologies:
