There are three code generation providers specific to MVC. They allow you to declare MVC controllers, MVC actions and MVC views correspondingly:
With the help of CodeRush we can declare everything starting from undeclared local variables and members to undeclared objects like classes and structures. Here, we will take a look at the code declaration providers for declaring events and event handlers:
When writing a new code, it usually implies writing a not-declared code like a method invocation, property calls, etc. To help you quickly create the required declarations, there are a lot of code generation providers for declaring methods, properties, fields, locals and everything else. Let’s review the method and constructor code declaration providers:
The following code declaration features are available in CodeRush for generating new type declarations (in alphabetical order). Click on the name to learn more about a specific code provider.
Creates an ancestor class for an active type. Active type becomes a descendant of the created ancestor class.
Creates a descendant class providing overrides for abstract members.
Attributes provide a powerful method of associating declarative information by decorating elements of the code, such as types, methods, properties, parameters and assemblies. Once an attribute is associated with a program entity, it can be queried at run time and used in various cases, for example, associating a help document with program entities (via the Help attribute), or marking an item as out of date (via the Obsolete attribute).
CodeRush provides code providers for declaring classes, such as:
A delegate is a special kind of object that holds a reference to a method. Once a delegate is assigned a method, it behaves exactly like that method. It can have parameters and a return value. Using a delegate allows the programmer to encapsulate a reference to a method inside a delegate object.
