Hi, Spire is not a free tool to use. Instead please find the below link where you can get detailed implementations http://www.keepautomation.com/how_to/aspnet/csharp_barcode.html

You can first read the binary data files using the BinaryReader class as shown in the following https://docs.microsoft.com/en-us/dotnet/api/system.io.binaryreader?view=netframework-4.0 Once you have the binary data read, consider using something like the LEADTOOLS BarcodeWriter.WriteBarcode method (https://www.leadtools.com/sdk/barcode) to write the QR barcode you need. This C# code shows how you can do this: BarcodeWriter writer = engine.Writer; QRBarcodeData data = BarcodeData.CreateDefaultBarcodeData(BarcodeSymbology.QR) as QRBarcodeData; data.Bounds = new LeadRect(0, 0, image.ImageWidth, image.ImageHeight); QRBarcodeWriteOptions writeOptions = writer.GetDefaultOptions(data.Symbology) as QRBarcodeWriteOptions; writeOptions.XModule = 30; writeOptions.HorizontalAlignment = BarcodeAlignment.Near; writeOptions.VerticalAlignment = BarcodeAlignment.Near; data.Value = recognizedCharacters; //This is your binary data writer.CalculateBarcodeDataBounds( new LeadRect(0, 0, image.ImageWidth, image.ImageHeight), image.XResolution, image.YResolution, data, writeOptions); writer.WriteBarcode(image, data, writeOptions);

At First, read data from binary file into text: https://stackoverflow.com/questions/2426190/how-to-read-file-binary-in-c Second, search Free Spire.Barcode in NuGet Package Manager to reference free spire.barcode.dll. At last, use below code to generate QR code with the dll: BarcodeSettings settings = new BarcodeSettings(); settings.Type = BarCodeType.QRCode; settings.Data = " your text" ; settings.Data2D = "your text" ; settings.QRCodeDataMode = QRCodeDataMode.AlphaNumber; settings.X = 1.0f; settings.QRCodeECL = QRCodeECL.H; BarCodeGenerator generator = new BarCodeGenerator(settings); Image image = generator.GenerateImage(); image.Save( "QRCode.png" );
