Inline Variable refactoring

This refactoring allows you to replace all occurrences of a variable in the code with its initializer. Note that the refactoring should be only applied if the variable value stays unchanged after initialization.

In the example below, we use this refactoring to inline the reversed variable.

static string ReversedString(string input) { var chars = input.ToCharArray(); Array.Reverse(chars); var reversed = new string(chars); return reversed; }
static string ReversedString(string input) { var chars = input.ToCharArray(); Array.Reverse(chars); return new string(chars); }

Inline a variable

  1. Place the caret at the declaration or a usage of a variable in the editor.

  2. Do one of the following:

    • Press Control+Alt+N and then choose Inline Variable

    • Press Control+Shift+R and then choose Inline Variable

    • Right-click and choose Refactor | Inline Variable in 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.
