Inline Variable refactoring
Ctrl+Alt+N
ReSharper_InlineVariable
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.
Before refactoring | After refactoring |
|---|---|
public static string ReversedString(string input)
{
var chars = input.ToCharArray();
Array.Reverse(chars);
var reversed = new string(chars);
return reversed;
}
|
public static string ReversedString(string input)
{
var chars = input.ToCharArray();
Array.Reverse(chars);
return new string(chars);
}
|
To inline a variable
Place the caret at the declaration or a usage of a variable in the editor.
- Do one of the following:
Press Ctrl+Alt+N and then choose Inline Variable
Press Ctrl+Shift+R and then choose Inline Variable
Right-click and choose Refactor | Inline Variable in the context menu.
Choose in the main menu.
If no conflicts are found, ReSharper performs the refactoring immediately. Otherwise, it prompts you to resolve conflicts.
