Convert Extension Method to Plain Static refactoring

This refactoring helps you convert an extension method to a static method and update all usages in the current solution accordingly.

Consider the following example:

public static void DoSomething(this string s) { } private static void Test(string str) { str.DoSomething(); }
public static void DoSomething(string s) { } private static void Test(string str) { DoSomething(str); }

Convert an extension method into a static method

  1. Place the caret at the declaration or a usage of an extension method in the editor, or select it in the File Structure window window.

  2. Do one of the following:

    • Press Control+Shift+R and then choose Extension Method to Plain Static.

    • Right-click and choose Refactor | Extension Method to Plain Static from the context menu.

    • Choose ReSharper | Refactor | Convert | Extension Method to Plain Static… from the main menu.

  3. The refactoring is carried out without requiring you to specify any further options.
