Chapter 1: The Core Concepts of C#

According to computer experts, the best way to learn a programming language is by writing and analyzing codes. Thus, youll write an actual computer program before studying the language itself. This approach will help you to understand how C# works. Also, youll become familiar with the syntax and structures of this language.

Your First Program

Heres the code that you need to type:

This program prints Hello, C#! onto your computers default output device. Its still a raw program so you cant run it yet. For now, lets just analyze its structure. The next section will teach you how to compile and run programs using a command prompt and a programming environment.

How Does It Work?

This sample program consists of three parts:

1. The class definition;
2. The method definition; and
3. The methods contents.

Lets discuss each part in detail:

The Class Definition The initial line of the program defines a class named HelloCSharp. The most basic class definition has two sections: (1) the word class and (2) the name of the new class. In this example, HelloCSharp serves as the classs name. Youll find the contents of this class inside the pair of braces (i.e. { }).

The Method Definition This part is located at the third line of the program. Here, you defined a method known as Main(). All C# programs use the main() method as their starting point. Heres the syntax that you need to use:

As you can see, Main() needs to be void and static. The arguments (i.e. the part inside the parentheses) are completely optional. That means you can simplify the Main() function into:

Important Note: Your program wont run if youll enter the Main() method incorrectly.

The Methods Contents Youll find the contents of any method after its name. In general, a pair of braces encloses those contents. The fifth line of the sample program uses an object (i.e. System.Console) and a method (i.e. WriteLine()) to display a message on your computers console. As mentioned earlier, the message is Hello, C#!

Important Note: When working on Main(), you may arrange C# expressions and statements according to your preferences. You wont get any error message even if you arrange those expressions and/or statements randomly. However, your completed program will run those entries according to their position inside the methods body.

The Rules You Need To Remember When Writing Codes

C# A Case-Sensitive Computer Language

This language is case-sensitive. That means you need to be careful with letter capitalization when typing C# codes. Basically, C# treats power, Power, and POWER as three different objects.

Important Note: You need to remember this rule. It applies to all of the elements of any C# program (e.g. variables, constants, classes, etc.).

Use the Proper Format

You need to add tabs, spaces, and newline characters to your code to improve its readability. These characters, which are ignored by the C# compiler, give an excellent structure to your source codes.

For instance, you may remove the newline characters from the HelloCSharp code:

As an alternative, you may remove the tab characters from it:

The last two examples work fine in terms of compilation and program execution. However, they are difficult to analyze, modify, understand, and maintain.
