Value Tracking

ReSharper | Inspect | Value Origin/Destination
ReSharper_DfaReachingDefinitionsUp / ReSharper_DfaReachingDefinitionsDown

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.

To investigate member's value origins

  1. Place the caret at the name of a method, property, variable, field, etc. whose value you want to investigate.
  2. In the main menu, choose ReSharper | Inspect | Value Origin or press Ctrl+Shift+Alt+A and choose Value Origin in the Inspect This drop-down list.
  3. In the Inspection Results window that opens, you can investigate possible origins of the value.

  2. In the main menu, choose ReSharper | Inspect | Value Destination or press Ctrl+Shift+Alt+A and choose Value Destination in the Inspect This drop-down list.
