C# Beginner Tutorial

Me and myself

First of all, I want to introduce myself shortly. My name is George, I'm 23 years old and I learned to code in school. I was 15 years old as I started to code. Now I'm working for hardly 2 years as C# Programmer at a small company. I'm by far not a pro but I think I'm able to teach the basics 😉

Why I'm doing this

In my opinion, coding will be very important in the future. Everbody should understand the basics because it will be everywhere in everyone's life. Coding seems very complex in the beginning but If you have understood the basics one time you can do a lot with it. Even in different coding languages. So be patient and don't give up! 😃

Why C#

The best thing about C# or any other language in the .Net Framework is that you can use Visual Studio (VS) as IDE (integrated development environment). VS is a very powerful tool and if you ever used Eclipse or Netbeans for Java you know how good VS is! (sorry I'm a little C# fanboy :-D)
Secondly, I'm a 100% Windows User and with C# it's very easy to create desktop software with WinForms/WPF.

Preparations

The first thing you should do is to download Visual Studio. It's a big and powerful tool so the installation needs some time. Hit the Link! Visual Studio 2017
The installation is straightforward to the workloads screen:

https://docs.microsoft.com/en-us/visualstudio/install/modify-visual-studio
Here you have to choose what you want to install. No worry you can modify this at any time but better you install all you will need right now:

Universal Windows Platform development
.NET desktop Development
Data storage and processing

Your first Project

How I hated the theory coding hours in school! So let's stop talking and start coding!
Open up VS2017 and hit File -> New -> Project. Now you will see this screen:

Search for Visual C# on the left and click on Console App(.Net Framework). Type in a name at the bottom (example: FirstConsoleApp) and click Ok. Visual Studio is now creating a Solution, adds the Console Project and adds a Program.cs Class to the Project.

In the Program.cs Class we are able to start coding.
Change

static void Main(string[] args)
        {
        }

static void Main(string[] args)
        {
            Console.WriteLine("Hello Steemit");
        }

and use the shortcut Ctrl + F5 to build and run the program. If everything is working in the correct way a console window will pop up:

Okay great if this is working but it's a little boring right? Add some fun.
Change to

static void Main(string[] args)
        {
            Console.ForegroundColor = ConsoleColor.Green;
            Console.WriteLine("Hello Steemit");
            Console.WriteLine("Calculator");
            Console.WriteLine("Type in the first number");
            int number1 = int.Parse(Console.ReadLine());
            Console.WriteLine("Type in the second number");
            int number2 = int.Parse(Console.ReadLine());
            int result = number1 + number2;
            Console.WriteLine(number1 + " + " + number2 + " = " + result);
        }

and start it again! Great we now are able to sum numbers and change the font color!
Very easy and basic stuff but I think you're now able to play a little bit around with this knowledge.

I will keep this lessons short because of coding needs time. Trial and error method is a good start - you will learn a lot.
In the next post, I will split the code from this post up. What it means and do in the background. Yeah, I know - theory - but I will keep it simple and short 😉
