DevExpress CodeRush Tips&Tricks

The Smart Constructor CodeRush feature allows you to add constructors to the current class or structure, and pass type members, like fields and properties for initialization through its parameters. To choose fields and properties that will be passed to a new constructor, the following dialog is used:

The Create Descendant and Create Descendant (with virtual overrides) CodeRush code providers are now available not only on the type declaration but on any reference to a type inside source code, for example:

It allows to create derived classes without navigating to the declaration of the ancestor class.

Objects can be converted from one type to another, assuming that the types are compatible. Often this is achieved using implicit conversion or explicitly with the cast operator. To perform an explicit casting, there are two approaches used:

• a cast-expression
• an ‘as’ operator

The Create Event Trigger CodeRush code provider generates an event trigger for the specified event. An event trigger is a single method that is used to raise an event. Although it is not strictly necessary to create such a trigger, it is useful, as it makes maintenance of the code simpler.

Unlike the local variable declarations, fields are simply variables that are declared directly within the code block of a class or a structure. Fields are declared in the type block by specifying the access level of the field, the type of the field and the name of the field. A field may also include a readonly modifier. This type of field can only have its value set directly in its declaration or from within a constructor of its containing class.

An enumeration type is a special set of related constants, each with an integer value. Enumerations are useful for defining states and sequences, particularly when there is a natural progression through those states. Each constant in the enumeration list can be compared and formatted using either its name or value. For example, assume that you have to define a variable whose value will represent a day of the week. There are only seven meaningful values which that variable will ever store. To define those values, you can use an enumeration type.

The simplest type of method is one that performs a task without requiring any parameters and without returning any information – let’s call them procedures (or void methods). Methods that use some type as the return value – are functions.

Sometimes, when we declare a method with a return value, we may realize that we don’t actually need this return value, and instead, need a simple void method that does not return anything. On the other hand, we marked a method as void, but may require it to be a function, returning a value.
