Rename refactoring

This refactoring allows you to change name of any symbol or project in your solution. All references to and usages of the symbol will be updated automatically.

Use the refactoring for different C# entities

Here is the list of entities that you can rename with this refactoring:

Namespace

You can also change its nesting level of the namespace. For example, you can rename namespace A.B.C to A.D.

Type

If the renamed type is located in file with the same name, ReSharper renames the containing file, too.

If the renamed type is a part of a hierarchy of types with similar names, for example class Foo : IFoo, you will be able to choose whether to rename the related types.

Method

If the method is a part of inheritance/implementation hierarchy, the related methods are renamed as well.

If the method has overloads, you will be able to choose whether to rename the overloads.

Field

If the field is used in a property with a matching name, you will be able to choose whether to rename the property.

Property

If the property has a backing field with a matching name, you will be able to rename the field as well.

Parameter

If the method is a part of inheritance/implementation hierarchy, or has overloads with a parameter of the same name and type, you will be able to rename parameters in the related methods, too.

Local variable

ReSharper renames local variables without showing the dialog:

  1. Select an entity in one of the following ways:

    • In the editor, set the caret at the name of an entity.

    • Select an entity in the Solution Explorer.

    • Select an entity in the File Structure window.

  3. Type a new name for the entity or use one of the suggested names.

    ReSharper: Rename refactoring

    ReSharper will suggest new names for the entity taking into account your naming style.

  4. Depending on the entity that you rename, select which related items should be renamed, for example, occurrences of the entity in comments and string literals.

  5. Click Next. If there are nothing related to the renamed entities, ReSharper applies the refactoring. Otherwise, the wizard displays additional steps:

    • If there are related entities with similar names, they are listed on the following step:

      ReSharper: Rename refactoring

      Select related entities that you want to rename along with the selected entity - you can accept the suggested names or specify new names in the New Name column.

    • If you have previously selected Search in comments and string literals and occurrences of the entity name is found, they are listed on the following step:

      ReSharper: Rename refactoring

      Select textual occurrences that you want ReSharper to rename.

  6. If no conflicts are found, ReSharper performs the refactoring immediately. Otherwise, it prompts you to resolve conflicts.

Perform the refactoring in-place

You can rename an entity by modifying its declaration right in the editor and then applying a quick-fix to invoke the solution-wide refactoring.

As soon as you change entity's name at its declaration, a grey border appears around the name, notifying you that the refactoring is available. You can press Alt+Enter to find the refactoring in the action list:
