C# Developer

Course Code: C-SHARP

Duration: 5 days


C# Developer Course Overview

The C# Developer course comprises sessions dealing with C# applications, variables and operators, decision and loop constructs, arrays, enums, methods, objects, classes, structs, delegates, events, object-oriented principles, exception handling, file IO, LINQ.

Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.

Course Objectives

This course aims to provide the delegate with the knowledge to be able to produce simple C# applications that exploit the core elements of the language including variables, expressions, selection and iteration, arrays, methods, classes and objects, structs, encapsulation, inheritance and polymorphism, exceptions, file IO and LINQ.

Who will the Course Benefit?

This course is aimed at anyone who wants to learn C# as a first language and developers who want to migrate to C# from another language, particularly those with little or no object-oriented knowledge.

Skills Gained

The delegate will learn and acquire skills as follows:

  • Writing, compiling, and executing simple C# applications
  • Understanding the relationship between C# and .NET
  • Declaring and initialising variables
  • Constructing expressions using relational, arithmetic and logical operators
  • Constructing decision and loop statements
  • Constructing and manipulating arrays and enums
  • Declaring and invoking methods using both parameters and return values
  • Creating classes, objects and structs
  • Encapsulating data
  • Implementing a hierarchical application design using inheritance
  • Exploiting polymorphism
  • Creating generic collections
  • Using delegates and events
  • Constructing simple lambda expressions
  • Throwing and catching exceptions
  • Reading and writing files
  • Using Language Integrated Query (LINQ)

Delegates attending this course should have some previous programming experience and be able to define general programming concepts including compilation, execution, variables, arrays, sequence, selection and iteration, navigate the filesystem (on the command line ideally), edit and save text files and browse the web. This knowledge can be obtained by attendance on the pre-requisite Introduction to Programming course.

Course Reviews

Very good and enjoyable course, have used C# beforehand but learnt some good things - delegates, lamdas, serialization & especially LINQ.

Gary - Senior S/W Engineer - Manufacturing - May 2022

Brian was very knowledgeable and took his time to explain and answer further questions. If there was a step 2 to this course I would be interested in doing this. This course has given me more confidence using visual studio and C#

Callum - Automotive - April 2022

Brian delivered the content in a very clear way, and was extremely helpful when it came to completing any exercises in the course book. Overall the course was very informative and covered a lot of information in a concise way, without being too much.

Sam - Apprentice Developer - IT - April 2022

The lecturer was very helpful. He explained all the topics well and was able to answer all questions myself and the other attendees asked. The course content was all delivered to a high standard, and was thoroughly studied. I feel as though I got a great deal of information out of the course. Even on topics I already had some prior knowledge on.

Frederick - Gen Pub & C/O - December 2021

Good course, very well explained by Brian. He was very patient and took questions from the group and gave us good working examples.

Dion - Project Co-Ordinator - IT

The trainer was amazing, patient, extremely knowledgeable about all aspects of the course and explained things in a way that was really easy to understand. Thank you so much for this week, I have learned a lot and would definitely recommend this course to anyone else.

Emma - Digital Implementation Consultant - IT
