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

Place the caret at the declaration or a usage of a variable in the editor.
Do one of the following:
- Press Control+Alt+N and then choose Inline Variable
- Press Control+Alt+Shift+T and then choose Inline Variable.
- Choose Refactor | Inline Variable from the main menu.
If no conflicts are found, JetBrains Rider performs the refactoring immediately. Otherwise, it prompts you to resolve conflicts.
Right after the refactoring has been completed, all changes that it makes anywhere, including other files, are registered as a single operation. So you can use the Undo action Control+Z to roll back all these changes with a single keystroke.
