C#通过第三方组件生成二维码(QR Code)和条形码(Bar Code)

用C#如何生成二维码,我们可以通过现有的第三方dll直接来实现,下面列出几种不同的生成方法:

 

1):通过QrCodeNet(Gma.QrCodeNet.Encoding.dll)来实现

1.1):首先通过VS2015的NuGet下载对应的第三方组件,如下图所示:

 1.2):具体生成二维码方法如下

        private void GenerateQRByQrCodeNet()
        {
            QrEncoder qrEncoder = new QrEncoder(ErrorCorrectionLevel.H);
            QrCode qrCode = new QrCode();
            qrEncoder.TryEncode("Hello World. This is Eric Sun Testing...", out qrCode);

            GraphicsRenderer renderer = new GraphicsRenderer(new FixedModuleSize(5, QuietZoneModules.Two), Brushes.Black, Brushes.White);

            using (MemoryStream ms = new MemoryStream())
            {
                renderer.WriteToStream(qrCode.Matrix, ImageFormat.Png, ms);
                Image img = Image.FromStream(ms);
                img.Save("E:/csharp-qrcode-net.png");
            }
        }

2):通过ThoughtWorks.QRCode(ThoughtWorks.QRCode.dll)来实现

1.1):首先通过VS2015的NuGet下载对应的第三方组件,如下图所示:

 1.2):具体生成二维码方法如下

        private void GenerateQRByThoughtWorks()
        {
            QRCodeEncoder encoder = new QRCodeEncoder();
            encoder.QRCodeEncodeMode = QRCodeEncoder.ENCODE_MODE.BYTE;//编码方式(注意:BYTE能支持中文,ALPHA_NUMERIC扫描出来的都是数字)
            encoder.QRCodeScale = 4;//大小(值越大生成的二维码图片像素越高)
            encoder.QRCodeVersion = 0;//版本(注意:设置为0主要是防止编码的字符串太长时发生错误)
            encoder.QRCodeErrorCorrect = QRCodeEncoder.ERROR_CORRECTION.M;//错误效验、错误更正(有4个等级)
            encoder.QRCodeBackgroundColor = Color.Yellow;
            encoder.QRCodeForegroundColor = Color.Green;
            string qrdata = "Hello 世界! This is Eric Sun Testing....";

            Bitmap bcodeBitmap = encoder.Encode(qrdata.ToString());
            bcodeBitmap.Save(@"E:\HelloWorld.png", ImageFormat.Png);
            bcodeBitmap.Dispose();
        }

                Type = BarCodeType.QRCode,
                TopTextColor = Color.Red,
                ShowCheckSumChar = false,
                ShowText = false
            };
            //Generate the barcode based on the this.barCodeControl1
            BarCodeGenerator generator = new BarCodeGenerator(bs);
            Image barcode = generator.GenerateImage();

            //save the barcode as an image
            barcode.Save(@"E:\barcode-2d.png");
        }

 

1.3):附加具体生成条形码方法如下

        private void GenerateBarCodeBySpire()
        {
            BarcodeSettings bs = new BarcodeSettings()
            {
                Data = "This is barcode: H2AMK-Z3V69-RTJZD-C7JAU-WILL4",
                ShowCheckSumChar = false,
                TopTextColor = Color.Red,
                ShowTopText = false,
                ShowTextOnBottom = true
            };
            //Generate the barcode based on the this.barCodeControl1
            BarCodeGenerator generator = new BarCodeGenerator(bs);
            Image barcode = generator.GenerateImage();

            //save the barcode as an image
            barcode.Save(@"E:\barcode.png");
        }

 

1.3):上诉代码我们发现生成的条形码和二维码带有水印[E-ICEBLUE],如何去除水印呢?请看如下代码

      BarcodeSettings.ApplyKey("......");
