C# Programming (.NET 3.5 and 4.0)

Audience

This course is for all developers requiring the skills to develop applications in Microsoft's C# language.

Prerequisites

Students should have some programming experience in a high-level language. Attending our one day 'Programming for Beginners' course would provide this.

Duration

5 days. Hands on.

Course Objectives

This is a thorough and comprehensive 5 day course providing a practical introduction to programming in C# utilising the services provided by .NET.  It is current to Visual Studio 2010 and .NET Framework 4.0, but also relevant to previous releases including Visual Studio 2008 .NET 3.5.  Delegates working on earlier releases need to advise us at the time of booking so that we can adapt the course content accordingly.

The course introduces object-oriented concepts at an early stage and C# is taught in a way that capitalises on this object orientation.  Besides supporting traditional OOfeatures, such as classes, inheritance and polymorphism, C# introduces several additional features such as properties, indexers, delegates, events, and interfaces. These make C# a compelling language for developing object-oriented and component-based systems.  This course provides thorough coverage of all these features and important new features such as implicit typing, extension methods, lambda expressions and Language-Integrated Query (LINQ) are looked at.

C# as a language is elegant and powerful. But to utilise 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 includes a succinct introduction to creating GUI programs using Windows Forms. Upon successful completion of this course, students will be able to:

• Implement programs using C# and classes from the .NET Framework.
• Implement simple GUI programs using Windows Forms.
• Work with C# Namespaces, Variables, Operators and Expressions.
• Understand C# Data Types.
• Control program execution with control structures.
• Understand Classes, Inheritance and Polymorphism.
• Work with Object Properties and Methods.
• Work with Character and String data.
• Understand Arrays and Indexers.
• Format and Convert Data.
• Handle Exceptions.
• Understand Interfaces.
• Understand Collections and Generic Types.
• Work with Delegates and Events.
• Create basic Windows Forms.
• Understand the new features in C# 4.0.
