If you don't want to use any 3rd party libraries, then I suggest you start looking at wikipedia on how barcodes work and then get the ISO documents, then you can use GDI+ to draw lines on a Graphics surface. Good luck ! — Neil

Let's take a look step by step.

Step 1: Download QRCODE GENERATOR LIBRARY from onbarcode.com.

Step 2: Open Visual Studio - Create New Project - Windows Form.

Step 3: Add reference to OnBarcode.Barcode.Winforms.dll.

Step 4: Design form with some input fields for accepting data to encode and the targeted location to save barcode generated image.

Step 5: To generate Barcode as well as Qrcode images write two differen methods as follows.

 private void GenerateBacode(string _data, string _filename) { Linear barcode = new Linear(); barcode.Type = BarcodeType.CODE11; barcode.Data = _data; barcode.drawBarcode(_filename); } private void GenerateQrcode(string _data, string _filename) { QRCode qrcode = new QRCode(); qrcode.Data = _data; qrcode.DataMode = QRCodeDataMode.Byte; qrcode.UOM = UnitOfMeasure.PIXEL; qrcode.X = 3; qrcode.LeftMargin = 0; qrcode.RightMargin = 0; qrcode.TopMargin = 0; qrcode.BottomMargin = 0; qrcode.Resolution = 72; qrcode.Rotate = Rotate.Rotate0; qrcode.ImageFormat = ImageFormat.Gif; qrcode.drawBarcode(_filename); }

Conclusion:

In this way you can generate barcode and qrcode images in C#. Output will look like bellow
