Learning a new language or switching to an entirely different technology is a common industry demand. As a student one should prepare oneself to be up to date with market trends, and as a professional, one should be aware of the new things that are coming in with new technologies. To meet this demand, there are a lot of books that are of thousand pages long and aim to be comprehensive references to the C# programming language. This book is entirely different and written so that someone who has a very basic knowledge of the C# language, or is a professional and working with another language but wants to switch, can learn C#. This book was designed with the aim that one should start with the basics and progress to an advanced level. The book contains concise content with relevant examples to explain everything. There are a lot of sections in the book that will encourage you to learn more ; with this knowledge, you can impress your colleagues, employers, or batch-mates. There will be a few terms you will hear first time – no problem, you can learn about them in this book. At the end of every section you will find a hands-on exercise section that will build confidence and give you ideas for solving practical problems. You can find various hints in these exercises. For the code examples, you can go to the GitHub repository (https://github.com/PacktPublishing/Learn-CSharp-in-7-days/) and download the source code for all chapters. You can easily use these code example in Visual Studio 2017 Update 3 by following the instructions mentioned thereon.
Chapter 1, Day 01 - Overview of the .NET Framework, gets you familiar with C#, including .NET Framework and .NET Core.
Chapter 2, Day 02 - Getting Started with C#, gives you a basic understanding of C# by iterating through the type system and the use of various constructs. The use and importance of reserved keywords, understanding statements, type conversions.
Chapter 3, Day 03 - What's New in C#, gets you familiar with various new important features introduced in versions 7.0 and 7.1.
Chapter 4, Day 04 - Discussing C# Class Members, explains the fundamentals of class and its members will be explained including indexers, the filesystem, exception handling, and string manipulation with regular expressions.
Chapter 5, Day 05 - Overview of Reflection and Collections, covers working with code using reflection, and an introduction to collections, delegates, and events.
Chapter 6, Day 06 - Deep Dive with Advanced Concepts, teaches you about implementing attributes, using preprocessors, and understanding generics and their usage, including sync and async programming.
Chapter 7, Day 07 - Understanding Object-Oriented Programming withC#, In this chapter we will learn all 4-paradigm of oop and implement using C# 7.0.
Chapter 8, Day 08 - Test Your Skills – Build a Real-World Application, helps you to write a complete application with the help of what you learned from this book.
All supporting code samples in this book have been tested on .NET Core 2.0 using Visual Studio 2017 update 3, database using SQL Server 2008R2 or later on the Windows platform.
Learn C# in 7 Days is a fast-paced guide. In this book, we take a unique approach to teaching C# to an absolute beginner, who will be able to learn the basics of the language in seven days. This practical book comes with important concepts that introduce the foundation of the C# programming language. This book addresses the challenges and issues that most beginners face. It covers issues such as the need to learn C#, issues with setting up a development environment with C#, challenges such as mathematical operations, and other day-to-day problems. Its fast-paced writing style allows the reader to get up and running in no time. We begin with the absolute basics in the first chapter (variables, syntax, control flows, and so on), and then move on to concepts such as statements, arrays, string processing, methods, inheritance, I/O handling, and so on. Every chapter is followed by an exercise that focuses on building something with the language. This book is a fast-paced guide to get readers upto speed with the language. It works as a reference guide, describing the major features of C#. Readers will be able to build easy and simple code with real-world scenarios. By the end of this book, you will be able to take your skills to the next level, with a good knowledge of the fundamentals of C#.
In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning. Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "You will get the following code in the Program.cs class. This is the default code provided by Visual Studio; you can amend it as you need." A block of code is set as follows:
var class1 = newClassExample();
var class2 = new Day02New.ClassExample();
class1.Display();
class2.Display(); New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "From Workloads, select the options you want to install. For our book, we need .NET desktop development and ".NET Core.
