Getting Started with C#: A Step-by-Step Guide

Your First C# Program: Hello, World!

Let’s dive into the world of C# programming by creating a simple program that displays “Hello, World!” on the screen. This program may seem trivial, but it lays the foundation for more complex applications.

using System;

class HelloWorld 
{
    static void Main(string[] args) 
    {
        // Your code goes here
        System.Console.WriteLine("Hello, World!"); 
    }
}

The Anatomy of a C# Program

Take a closer look at the code, and you’ll notice that even a basic C# program requires several lines of code. Don’t worry; every C# program follows a similar structure. Your code will live inside the curly braces { }, replacing the // Your code goes here comment.

Breaking Down the Code

Let’s examine the first C# program we wrote:

System.Console.WriteLine("Hello, World!"); 

Notice the crucial line of code: System.Console.WriteLine(). When working with this method, keep the following in mind:

• Everything you want to print should be wrapped inside parentheses (()).
• The text to be printed must be enclosed within double quotes “”.
• Each System.Console.WriteLine() statement concludes with a semicolon ;.

Failure to adhere to these rules will result in errors, and your code won’t execute successfully.

Now that we’ve covered the basics of a C# program, it’s time to explore another essential aspect of programming: comments. Stay tuned to learn how to effectively use comments in your C# code! Learn more about comments in C#.
