This refactoring helps you replace a field with its value and remove its declaration. For obvious reasons, the refactoring can be applied to a filed that has only one write usage. This may be a constant or readonly field, or a field that is initialized and used in the same function.
If the target field has conditional or complex assignment and it is used within a single function, ReSharper will create a local variable to handle the value of the field.

In the example below, we use this refactoring to inline a constant that has a single usage:

Before refactoringAfter refactoring
class Shape { private const string ErrorMessage = "Something has failed"; public void Draw(string s) { try { // draw } catch (Exception e) { Console.WriteLine("{0} : {1}", ErrorMessage, e); } } }
class Shape { public void Draw(string s) { try { // draw } catch (Exception e) { Console.WriteLine("{0} : {1}", "Something has failed", e); } } }

To inline a field

  1. Place the caret at the declaration or a usage of a field, which has only one write usage.
  2. Do one of the following:
    • Press Ctrl+Alt+N and then choose Inline Field
    • Press Ctrl+Shift+R and then choose Inline Field
    • Right-click and choose Refactor | Inline Field on the context menu.
    • Choose ReSharper | Refactor | Inline | Inline… in the main menu.
  3. If no conflicts are found, ReSharper performs the refactoring immediately. Otherwise, it prompts you to resolve conflicts.
