Convert Indexer to Method refactoring
This refactoring helps you convert one or both accessors of an indexer into methods and update usages of the indexer in the current solution accordingly.
tip
The reverse functionality is available with the Convert Method to Indexer refactoring refactoring.
In the example below JetBrains Rider converts both getter and setter accessors of the indexer and updates the usage:
Before refactoring
class BookLibrary{ private Book[] books = new Book[1000]; public Book this[int index] { get => books[index]; set => books[index] = value; } public void TestInsertBookAt(Book book, int index) { this[index] = book; }}After refactoring
class BookLibrary{ private Book[] books = new Book[1000]; public void SetItem(int index, Book value) => books[index] = value; public Book GetItem(int index) => books[index]; public void TestInsertBookAt(Book book, int index) { SetItem(index, book); }}Place the caret at
thiskeyword of an indexer in the editor or select an indexer in the Structure window window.Do one of the following:
Press CtrlShift0R and then choose Convert Indexer to Method(s).
Choose Refactor | Convert Indexer to Method(s) from the main menu.
The Convert Indexer to Method(s) dialog will open.
Use controls in the dialog to choose which accessors should be converted and to specify names for the created methods.
To apply the refactoring, click Next.
If no conflicts are found, JetBrains Rider performs the refactoring immediately. Otherwise, it prompts you to resolve conflicts.
tip
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 Ctrl0Z to roll back all these changes with a single keystroke.
tip
In Visual Basic, this refactoring can be applied to the default property.
