Add Parameter

Expanded Purpose

Adds a new parameter to a method signature and update all method references.


Add Parameter is a cascading Code Provider. That means that the Code Provider affects all method calls and method declarations in interfaces, base and descendant classes.

Expanded Availability

Available when the cursor is in a method signature or in the arguments list in the method reference.

Expanded Usage

  1. Place the caret in a method signature.


    The blinking cursor shows the caret's position at which the Code Provider is available.

  2. Use the Ctrl + . or Ctrl + ~ shortcut to invoke the Code Actions Menu.
  3. Select Add Parameter from the menu.
  4. Specify the type of new parameter and press Enter.
  5. For the base method and all overridden implementations, specify the parameter name. Use the Enter key to switch between method overrides.
  6. For each method reference, specify what is passed to the method as a newly added parameter. Use the Enter key to switch between method usages.

After execution, the Code Provider adds a new method parameter and updates all method usages.


Being called from the method arguments list, this Code Provider determines the parameter type automatically, according to the passed argument type.

Expanded Adding Parameters Passed by Reference

You can also specify the out or ref keyword if the parameter should be passed onto a method by reference. Consider the code snippet below.

Follow the instructions from the Usage section to add a new parameter and specify the "ref int" string as a new parameter's type (add ByRef in VB). If the out or ref keyword was specified, CodeRush passes the corresponding variable on method usages and declares/initializes it if required.
