C # using Third-party components to generate a two-dimensional code rollup _c# tutorial

How to generate two-dimensional code in C #, which we can implement directly from existing Third-party DLLs, lists several different build methods:

1. Through Qrcodenet (Gma.QrCodeNet.Encoding.dll) to achieve

1.1): First download the corresponding Third-party components through the VS2015 NuGet, as shown in the following figure:

1.2): The concrete generation of two-dimensional code method is as follows

    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. Through Thoughtworks.qrcode (ThoughtWorks.QRCode.dll) to achieve

1.1): First download the corresponding Third-party components through the VS2015 NuGet, as shown in the following figure:

1.2): The concrete generation of two-dimensional code method is as follows

    private void Generateqrbythoughtworks ()
    {
      Qrcodeencoder encoder = new Qrcodeencoder ();
      Encoder. Qrcodeencodemode = Qrcodeencoder.encode_mode. byte;//encoding Method (Note: Byte can support Chinese, alpha_numeric scan is the number)
      encoder. Qrcodescale = 4;//size (the larger the value generated two-dimensional code picture pixels higher)
      encoder. Qrcodeversion = 0;//Version (note: setting to 0 is primarily to prevent errors that occur when the encoded string is too long)
      encoder. Qrcodeerrorcorrect = qrcodeencoder.error_correction. m;//error parity, error correction (with 4 levels)
      encoder. Qrcodebackgroundcolor = Color.yellow;
      Encoder. Qrcodeforegroundcolor = Color.green;
      String qrdata = "Hello world!" This is Eric Sun testing ... ";

      Bitmap Bcodebitmap = encoder. Encode (Qrdata. ToString ());
      Bcodebitmap.save (@ "E:\HelloWorld.png", imageformat.png);
      Bcodebitmap.dispose ();
    }

3): Through Spire.barcode (Spire.BarCode.dll) to achieve

1.1): First download the corresponding Third-party components through the VS2015 NuGet, as shown in the following figure:

1.2): The concrete generation of two-dimensional code method is as follows

    private void Generateqrbyspire ()
    {
      barcodesettings bs = new barcodesettings ()
      {
        Data = "This is QR code." ,
        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): Additional specific generated barcode method is as follows

    private void Generatebarcodebyspire ()
    {
      barcodesettings bs = new barcodesettings ()
      {
        Data = "This is Barcode. ",
        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");
    }

3. Through Barcodelib (BarcodeLib.Barcode.ASP.NET.dll) to achieve

Download the corresponding DLL connection for http://www.barcodelib.com/asp_net/

4.1): The concrete generation of two-dimensional code method is as follows

    private void Generateqrbybarcodelib ()
    {
      QRCode qrbarcode = new QRCode ();
      Qrbarcode. Encoding = Qrcodeencoding.auto;
      Qrbarcode. Data = "336699885522 This is Eric Sun testing.";

      Qrbarcode. Modulesize = ten;
      Qrbarcode. LeftMargin = 8;
      Qrbarcode. RightMargin = 8;
      Qrbarcode. TopMargin = 8;
      Qrbarcode. BottomMargin = 8;
      Qrbarcode. imageformat = System.Drawing.Imaging.ImageFormat.Gif;

      Save QR Code Barcode image into your system
      Qrbarcode.drawbarcode ("E:/csharp-qrcode-lib.gif");
    

4.2): Additional specific generated barcode method is as follows

    private void Generatelinearbybarcodelib ()
    {
      Linear barcode = new Linear ();
      Barcode. Type = barcodetype.code128;
      Barcode. Data = "CODE128";
      Other barcode settings.

      Save barcode image into your system
      Barcode.drawbarcode ("E:/barcode.png");
    }
