410. Object-Oriented
Programming in C#
Rev. 2.3
Microsoft’s .NET is a revolutionary advance in programming
technology that greatly simplifies application development and is a good match
for the emerging paradigm of Web-based services, as opposed to proprietary
applications. Part of this technology is a new language, C#. This new language
combines the power of C++ and the ease of development of Visual Basic. It bears
a striking resemblance to Java and improves on that language. C# may well
become the dominant language for building applications on Microsoft platforms.
This thorough and comprehensive course is a practical introduction
to programming in C#, utilizing the services provided by .NET. This course
emphasizes the C# language. It is current to Visual Studio 2005 and .NET 2.0,
which introduces important new features, such as generic types. The new
features are covered throughout the course in the context of where they are
applicable.
This course is intended to be fully accessible to programmers who do
not already have a strong background in object-oriented programming in C-like
languages, such as C++ or Java. It is ideal, for example, for Visual Basic or
COBOL programmers who desire to learn C#.
An important thrust of the course is to teach C# programming from an
object-oriented perspective. It is often difficult for programmers trained
originally in a procedural language to start “thinking in objects.” This course
introduces object-oriented concepts early, and C# is developed in a way that
leverages its object orientation. A case study is used to illustrate creating a
complete system using C# and .NET. Besides supporting traditional
object-oriented features, such as classes, inheritance, and polymorphism, C#
introduces several additional features, such as properties, indexers,
delegates, events, and interfaces that make C# a compelling language for
developing object-oriented and component-based systems. This course provides
thorough coverage of all these features.
C# as a language is elegant and powerful. But to utilize its
capabilities fully, you need to have a good understanding of how it works with
the .NET Framework. The course explores several important interactions between
C# and the .NET Framework, and it includes an introduction to major classes for
collections, delegates, and events. It concludes with a succinct introduction
to creating GUI programs using Windows Forms.
Numerous programming examples and exercises are provided, including
the case study. The student will receive a comprehensive set of materials,
including course notes and all the programming examples.
The course includes two electronic supplements, provided as PDF
files. The first covers Visual Studio 2005, and the second covers unsafe code
and the C# pointer type. Related learning materials include the book Introduction to C# Using .NET, published
by Prentice-Hall, and a comprehensive set of supplementary exercises, available
from Object Innovations.
