Qr code are very famouse nowadays so I will teach you how to generate qr code using c# and net core. I will do an example how to encode a url.
It is very simple. Of course it is simple because somebody works hard and developed a library for us.
This library is Qr coder. It is defined like “A pure C# Open Source QR Code implementation“. You can see the full documentation and source code in github.
I am using net core 7 at the moment I write this article.
If you want to know more details about Qr code and how to it works, you can read a very good definition in wikipedia.
private static void Main(string[] args){
Console.WriteLine("QR Codes");
Url generator = new Url("https://www.developingthedeveloper.dev/");
string payload = generator.ToString();
QRCodeGenerator qrGenerator = new QRCodeGenerator();
QRCodeData qrCodeData = qrGenerator.CreateQrCode(payload, QRCodeGenerator.ECCLevel.Q);
SvgQRCode qrCode = new SvgQRCode(qrCodeData);
string qrCodeAsSvg = qrCode.GetGraphic(20);
string file = @"c:/Home/Blog/example.svg";
byte[] data = Encoding.ASCII.GetBytes(qrCodeAsSvg);
System.IO.File.WriteAllBytes(file, data);
}
