Convert Static to Extension Method refactoring
ReSharper | Refactor | Convert | Static to Extension Method…
To assign a shortcut, go to Tools | Options | Environment | Keyboard and find the ReSharper_Static2ExtensionAction command.
This refactoring helps you convert a static method to an extension method, provided that the static method:
Has at least one parameter.
Resides in a non-generic, non-nested static class.
Consider the following example:
Before refactoring
static class Foo{ public static string Reverse(string input) { var chars = input.ToCharArray(); Array.Reverse(chars); return new string(chars); } static void Test(string str) { str = Reverse(str); }}After refactoring
static class Foo{ public static string Reverse(this string input) { var chars = input.ToCharArray(); Array.Reverse(chars); return new string(chars); } static void Test(string str) { str = str.Reverse(); }}tip
The reverse functionality is available with the Convert Extension Method to Plain Static refactoring refactoring.
Place the caret at the declaration or a usage of a static method in the editor, or select it in the File Structure window window.
Do one of the following:
Press and choose Convert Static Method to Extension.
Press and then choose Convert Static Method to Extension.
Right-click and choose Refactor | Convert Static Method to Extension from the context menu.
Choose ReSharper | Refactor | Convert | Static to Extension Method… from the main menu.
If no conflicts are found, ReSharper performs the refactoring immediately. Otherwise, it prompts you to resolve conflicts.
