CS02 - C# Primer - 3 Days

Course Description

This course is designed for the novice developer or those with little or no experience of C# who require an introduction to the C# language using the Microsoft Visual Studio IDE.

Pre-requisites

The student should be familiar with the Windows host environment. Knowledge of any programming language is advantageous but not essential.

Objectives

This course provides students with the skills to write simple C# programs. The syntax of the language is covered in detail and also Object Oriented coding techniques are discussed.

During the course the student will write many applications to ensure that the concepts and statements taught are fully understood and practical experience is gained.

The course is taught using Microsoft's Visual Studio IDE. The skills needed to use this software are presented as part of the course.

On completion of this course the student will be able to:

  • use the major concepts of a modern, block-structured, high-level language, such as control flow, function calls and modular programming
  • structure programs using classes and other essential object-oriented features
  • create, test and debug simple C# code using the Visual Studio Integrated Development Environment (IDE)

Environment

Development will be performed using:

  • Microsoft Visual Studio

Customisation

For on-site courses (i.e. at your premises), we are more than happy to tailor the course agenda to suit your exact requirements. In many cases, we are able to build your in-house standards and naming conventions into the delivered course.

Course Format

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 build a simple but complete application.

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.
