使用QRCoder生成二维码

官方地址：https://github.com/codebude/QRCoder

首先安装相应的package

最简单的使用

     public void GenerateRun(string content)
        {
            QRCodeGenerator qrGenerator = new QRCodeGenerator();
            QRCodeData qrCodeData = qrGenerator.CreateQrCode(content, QRCodeGenerator.ECCLevel.Q);
            QRCode qrCode = new QRCode(qrCodeData);
            Bitmap qrCodeImage = qrCode.GetGraphic(20);
           
            string filePath = "D:\\ImportData\\" + "\\QR-coder.jpg";
            qrCodeImage.Save(filePath, ImageFormat.Jpeg);
            Console.WriteLine("generate finished");
        }

设置颜色或是否周围是否有白边

     public void GenerateRun(string content)
        {
            QRCodeGenerator qrGenerator = new QRCodeGenerator();
            QRCodeData qrCodeData = qrGenerator.CreateQrCode(content, QRCodeGenerator.ECCLevel.Q);
            QRCode qrCode = new QRCode(qrCodeData);
            //Bitmap qrCodeImage = qrCode.GetGraphic(20);

            //drawQuietZones 是否有白边
            Bitmap qrCodeImage = qrCode.GetGraphic(5, Color.Purple, Color.White, false);
           
            string filePath = "D:\\ImportData\\" + "\\QR-coder.jpg";
            qrCodeImage.Save(filePath, ImageFormat.Jpeg);
            Console.WriteLine("generate finished");
        }

设置logo

Bitmap qrCodeImage = qrCode.GetGraphic(20, Color.Black, Color.White, (Bitmap)Bitmap.FromFile("C:\\myimage.png"));

还有一些其它的支持功能

支持生成是WIFI数据的二维码

   public void GenerateRun(string content)
        {
            QRCodeGenerator qrGenerator = new QRCodeGenerator();
            //WIFI
            PayloadGenerator.WiFi wifiPayload = new PayloadGenerator.WiFi("MyWiFi-SSID", "MyWiFi-Pass", PayloadGenerator.WiFi.Authentication.WPA);
            content = wifiPayload.ToString();
            QRCodeData qrCodeData = qrGenerator.CreateQrCode(content, QRCodeGenerator.ECCLevel.Q);
            QRCode qrCode = new QRCode(qrCodeData);
            Bitmap qrCodeImage = qrCode.GetGraphic(10);

            string filePath = "D:\\ImportData\\QR-coder.jpg";
            qrCodeImage.Save(filePath, ImageFormat.Jpeg);
            Console.WriteLine("generate finished");
        }

支持生成包含二维码的PDF

 public void GeneratePDF(string content)
        {
            QRCodeGenerator qrGenerator = new QRCodeGenerator();
            QRCodeData qrCodeData = qrGenerator.CreateQrCode(content, QRCodeGenerator.ECCLevel.Q);
            PdfByteQRCode qrCode = new PdfByteQRCode(qrCodeData);
            byte[] qrCodeAsPdfByteArr = qrCode.GetGraphic(20);

            string filename = "D:\\ImportData\\QR-coder.pdf";
            FileStream fs = new FileStream(filename, FileMode.Create, FileAccess.Write);
            fs.Write(qrCodeAsPdfByteArr, 0, qrCodeAsPdfByteArr.Length);
            fs.Close();
            Console.WriteLine("generate pdf finished");
        }
