Some OOP Concepts • Class – a master for creating child objects; often have plural names • Object – a thing, a noun • Property – a characteristic of an object; an adjective for the noun • Value – data for the property, either null, or default, or supplied by you The University of North Texas, ITDS Dept., Dr. Vedder

Some OOP Concepts, 2 • Method – functionality for the object; a verb • Event – action recognized by an object (recognition is automatic, response is not – you must program); there is a ‘null event’ The University of North Texas, ITDS Dept., Dr. Vedder

Object Members / Class Members • Everything that can belong to an object or to its parent class • Properties, methods, enumerations, fields, structures, etc. The University of North Texas, ITDS Dept., Dr. Vedder

Scope • The zone of visibility for a class, object, procedure, etc. • Many scope qualifier keywords, ex., • Public: visible to the entire project • Private: visible only to the current module • Encapsulation – hiding the inner workings of a class or child object; using scope qualifiers to create an interface between public and private, as with a TV remote The University of North Texas, ITDS Dept., Dr. Vedder

Assigning Values to Properties • Template – theme with default text • Theme – collection of styles applied to entire document • Style – collection of formats applied to a section of a document • Individual format (of a selected object); anything the developer can see on the screen is an object, especially if selectable. The University of North Texas, ITDS Dept., Dr. Vedder

Naming Conventions • Both XAML and C# are case-sensitive • “CamelCase”: ex., romanHolidayVacation • Underscore prefix often used with private variables and object variables, ex., _premiumGasCost The University of North Texas, ITDS Dept., Dr. Vedder

What is a “Namespace”? • Library of related class definitions • Required for all .NET projects • Xaml pages: xmlns statements • C# files: using statements • Examples: • xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" l) • using System.IO; • Your own project or xaml page The University of North Texas, ITDS Dept., Dr. Vedder
