Generating Type Constructors
The constructor generation wizard creates a non-default constructor that takes parameters for selected fields , properties and auto-properties .
All generated constructors follow the same pattern where:
- Each field , property, or auto-property included in the constructor is initialized with a parameter.
- The name of the parameter is derived from the name of the corresponding field or property .
If there are non-default base type constructors, the required parameters are added to the generated constructor and passed to the base class constructor.
In the example below, this command is used to generate a new
Circle constructor that takes two additional parameters to initialize
To generate a constructor
