ReSharper 2022.1 Help

Value tracking

Value Tracking helps you investigate value of a particular type and possibly determine how a certain incorrect value might have passed to a given point in your program, and where it might be passed next. This helps you investigate possible NullReferenceException, inappropriate behavior, and reasons why you get incorrect values.

  1. Place the caret at the name of a method, property, variable, field, and so on, whose value you want to investigate.

  2. In the main menu, choose ReSharper | Inspect | Value Origin or press Control+Shift+Alt+A and choose Value Origin in the Inspect This list.

  3. In the Inspection Results window that opens, you can investigate possible origins of the value.
