C# OO Primer

Course Objectives
Whilst covering the basics of C# object oriented programming concepts, this Course also aims to give an insight into objects, classes and messaging. Issues such as encapsulation, inheritance, polymorphism, object modelling and the Unified Modelling Language are discussed. On completion of this Course the student will be able to:

• Understand the concepts of object oriented programming
• Understand and differentiate between objects and classes
• Understand object instantiation
• Understand and differentiate between instance methods and variables and class methods and variables
• Understand the concept and benefits of messaging
• Understand the concept and benefits of encapsulation
• Understand the concept and benefits of inheritance
• Understand the concept and benefits of interfaces
• Understand the concept and benefits of polymorphism
• Understand the concept of object modelling and the Unified Modelling Language

Target Audience
This course is designed to provide the developer with a broad overview of the C# object oriented approach. Developers will learn the key elements of object oriented applications including classes, interfaces, attributes, objects, access levels, inheritance and polymorphism. Although this course does not instruct the developer on full detailed object oriented design techniques, on completion of this course, developers will be ready to move on to more detailed C# training courses in a 'non-design' capacity.

Course Format: Interactive practical sessions make up a large part of the course, allowing delegates to demonstrate and reinforce the lectures given. During these sessions the delegate will gain experience of object oriented programming concepts. Examples are used extensively, ranging from simple code snippets to full applications with complete 'real world' functionality. These are supplied at the start of the course and it is encouraged that the delegates execute and 'experiment' with these under the instructor's guidance as they are introduced.

These examples are available to take away, along with the delegate's own work. The comprehensive Student Guide supplied is fully indexed serving as a useful reference tool long after the course has finished. Delegates will also be able to access a free help-line with technical questions relating to topics covered on the course.
