Jamie Chan - Learn C# in One Day and Learn It Well: C# for Beginners with Hands-on Project

Learn C# In One Day and Learn It Well C# for Beginners with Hands-On Project The only book you need to start coding in C# immediately By Jamie Chan http://www.learncodingfast.com/csharp Copyright 2015 All rights reserved.

All examples in the book are carefully chosen to demonstrate each concept so that you can gain a deeper understand of the language. Topics are carefully selected to give you a broad exposure to C#, while not overwhelming you with information overload. These topics include object-oriented programming concepts, error handling techniques, file handling techniques and more. In addition, as Richard Branson puts it: "The best way of learning about anything is by doing". This book comes with a project where youll be guided through the coding of a simple payroll software from scratch. The project uses concepts covered in the book and gives you a chance to see how it all ties together.

You can download the source code for the project and all the sample programs in this book at

Whether you are a seasoned programmer or a complete novice, this book is written to help you learn C# programming fast. Topics are carefully selected to give you a broad exposure to C# while not overwhelming you with information overload. By the end of the book, you should have no problem writing your own C# programs. In fact, we will be coding a simple payroll software together as part of the project at the end of the book. Ready to start? First, lets answer a few questions: What is C#? C#, pronounced as C Sharp, is an object-oriented programming language developed by Microsoft in the early 2000s, led by Anders Hejlsberg.

It is part of the .Net framework and is intended to be a simple general-purpose programming language that can be used to develop different types of applications, including console, windows, web and mobile applications.
Like all modern programming languages, C# code resembles the English language which computers are unable to understand. Therefore, C# code has to be converted into machine language using what is known as a compiler ( refer to footnote ). The compiler that well be using in this book is the free Visual Studio Community 2015 provided by Microsoft. Why Learn C#? C# has syntax and features that resemble other programming languages like Java and C++. As such, if you have any prior programming experience, you will find learning C# a breeze. Even if you are totally new to programming, C# is designed to be easy to learn (unlike C or C++) and is a great first language to learn.

In addition, C# is part of the .Net framework. This framework includes a large library of pre-written code that programmers can use without having to write everything from scratch. This allows programmers to rapidly develop their applications in C#, making C# the ideal language to work with if you are on a tight schedule. Lastly, C# is an object-oriented programming (OOP) language. Object-oriented programming is an approach to programming that breaks a programming problem into objects that interact with each other. Well be looking at various object-oriented programming concepts in this book.

Once you master C#, you will be familiar with these concepts. This will make it easier for you to master other object-oriented programming languages in future. Ready to dip your toes into the world of C# programming? Lets get started. Footnote:
The conversion of a C# program into machine language is actually a bit more complicated than this. Visual Studio Community merely converts a C# program into MIL, which stands for Microsoft Intermediate Language. This MIL code is then converted into machine language by a virtual execution system known as the Common Language Runtime.

Nonetheless, for our purpose, we do not need to know these intricate details to develop our own C# programs. Chapter 2: Getting ready for C# Installing Visual Studio Community Before we can start developing applications in C#, we need to download Visual Studio Community. As mentioned in Chapter 1, Visual Studio Community (VSC) is a free complier provided by Microsoft. In fact, VSC is more than just a compiler. It is an Integrated Development Environment (IDE) that includes a text editor for us to write our code and a debugger to help us identify programming errors.

To download VSC, go to https://www.visualstudio.com/en-us/products/visual-studio-community-vs.aspx . Click on the Download Community 2015 button to download the file. Once you have downloaded the file, double click to install VSC. After you install, youll be prompted to restart your computer. Once you restart your computer, you are ready to start coding your first C# program. Your First C# Program To write our first program, lets create a folder on our desktop and name it C# Projects.

We will save all our C# projects to this folder. Next, launch VSC and select File > New > Project. (You may have to search for Visual Studio 2015 if you cannot find VSC.) The first program that we are going to write is a console application. Console applications refer to programs that have no graphical user interface. From the New Project dialog box, select Visual C# > Windows (on the left) and select Console Application in the main box. Name this program HelloWorld and save it in the C# Projects folder created earlier.

You can use the Browse button to browse to the correct folder. Finally, click OK to create the project. You will be presented with a default template that VSC created for you automatically. Replace the code in the template with the code below. Note that line numbers are added for reference and are not part of the actual code. You may want to bookmark this page for easy reference later when we discuss the program.

Due to the small screen sizes of most mobile devices, the code may look jumbled up if you are viewing it on a Kindle, tablet or mobile phone. If you have problems reading the code, you can try changing your screen to landscape mode. Alternatively, you can download the source code for this sample program and all other sample programs in this book at http://www.learncodingfast.com/csharp . 1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.Threading.Tasks; 7 namespace HelloWorld 8 { //A Simple Program to display the words Hello World class Program { static void Main(string[] args) { Console.WriteLine("Hello World"); Console.Read(); } } 20 } I strongly encourage that you type the code yourself to get a better feel for how VSC works. As you type, you will notice that a box appears near the cursor with some help messages occasionally. That is known as Intellisense.
