QR is the trademark for a type of matrix barcode (or two-dimensional barcode) first designed for the automotive industry in Japan. This QR code is also used in automobiles. If customer wanst to know about the part details, then only a mobile app is needed to read it. We are using QR code to read all data with security.

A company gives a customer security key for reading QR code. My project came and said I want a QR code with Security key. So I decided make a QR code using C#. I know in C# we have a lot of DLL (library) or Third party software also available in market to make QR codes.

I have created one image to display the QR code in report, this image binds in RDLC report.

Bind image in report.

Figure: Showing how to bind image

One question arises, that this is a static way, not dynamic. But don't worry we can pass image parameters according to our requirement.

// Bind the image dynamically in parameters.
ReportParameter parameter = new ReportParameter(
    "QR_Img",
    "file:\\" + Application.StartupPath + "test.png",
    true
);

Page setting as per requirement.

System.Drawing.Printing.PageSettings pg = new System.Drawing.Printing.PageSettings();

// Margin Top set here...
pg.Margins.Top = 1;

// Margin bottom set here
pg.Margins.Bottom = 1;

// Margin left set here
pg.Margins.Left = 0;

// Margin right set here
pg.Margins.Right = 0;

reportViewer1.SetPageSettings(pg);

// Hide the print button
this.reportViewer1.ShowPrintButton = false; // if you want print button on show in preview then set True here..

this.reportViewer1.RefreshReport();

// Set the parameters in report viewer
this.reportViewer1.LocalReport.SetParameters(parameter);

// Refresh here... clear all old values..
this.reportViewer1.LocalReport.Refresh();

this.reportViewer1.SetDisplayMode(DisplayMode.PrintLayout);

Create the QR code.

// Set information
string code = "Your information you want display in QR code";

QRCodeGenerator qrGenerator = new QRCodeGenerator();

// Create QR code
QRCodeGenerator.QRCode qrCode = qrGenerator.CreateQrCode(code, QRCodeGenerator.ECCLevel.Q);

// Pass the reference in bitmap
using (Bitmap bitMap = qrCode.GetGraphic(20))
{
    using (MemoryStream ms = new MemoryStream())
    {
        bitMap.Save(ms, System.Drawing.Imaging.ImageFormat.Png);

        byte[] byteImage = ms.ToArray();
        using (MemoryStream ms1 = new MemoryStream(byteImage))
        {
            img = Image.FromStream(ms1);
        }

        img = ResizeImage(img, 150, 150);

        RectangleF rectangleF = new RectangleF(10f, 0.0f, 0.0f, 0.0f);

        Image MyImage = new Bitmap(img);

        using (Graphics g2 = Graphics.FromImage(MyImage))
        {
            IntPtr dc2 = g2.GetHdc();
            g2.ReleaseHdc(dc2);
        }

        // Image save here...
        MyImage.Save(Application.StartupPath + "test.png", System.Drawing.Imaging.ImageFormat.Jpeg);
        // Change the save path of image... like this way
    }
}

Your QR Image is ready to display information.
