How to generate a QR code from a URL and insert it into a Word document during mail merge?

Syncfusion® Essential® DocIO is a .NET Word library used to create, read, edit, and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can generate a QR code from a URL and insert it into a Word document during mail merge using C#.

To convert a URL into a QR code in a Word document, generate the QR code using Essential® PDF, convert it into an image, and insert it in place of the URL string during mail merge.

Steps to generate a QR code from a URL and insert it into a Word document during mail merge:

1. Create a new .NET Core console application project.

2. Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your project from NuGet.org.
   

   

3. Install the Syncfusion.Pdf.Imaging.Net.Core NuGet package as a reference to your project from NuGet.org.
   

   

4. Include the following namespaces in the Program.cs file
   C#

using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;
using Syncfusion.Drawing;
using Syncfusion.Pdf.Barcode;
using Syncfusion.Pdf.Graphics;

5. Use the following code example to generate a QR code from a URL and insert it into a Word document during mail merge.
   C#

using (FileStream fileStreamPath = new FileStream(Path.GetFullPath("Data/Template.docx"), FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
    //Loads an existing Word document
    using (WordDocument document = new WordDocument(fileStreamPath, FormatType.Docx))
    {
        //Uses the mail merge events handler for image fields
        document.MailMerge.MergeImageField += new MergeImageFieldEventHandler(MergeField_ProductImage);
        //Gets the DataTable
        DataTable dataTable = GetDataTable();
        //Performs mail merge
        document.MailMerge.Execute(dataTable);
        // Saves the Word document file to file system    
        using (FileStream outputStream = new FileStream(Path.GetFullPath(@"Output/Result.docx"), FileMode.Create, FileAccess.ReadWrite, FileShare.ReadWrite))
            {
                document.Save(outputStream, FormatType.Docx);
            }
        }
    }
}

6. Use the following code example to bind the image from the QR code during the mail merge process.
   C#

private static void MergeField_ProductImage(object sender, MergeImageFieldEventArgs args)
{
   //Binds image from QR code during mail merge
   if (args.FieldName == "Website")
   {
       //Initialize a new PdfQRBarcode instance 
       PdfQRBarcode QRCode = new PdfQRBarcode();
       //Set the XDimension and text for barcode
       QRCode.XDimension = 3;
       QRCode.Text = args.FieldValue as string;
       //Convert the QR code to image 
       Stream barcodeImage = QRCode.ToImage(new SizeF(300, 300));
       barcodeImage.Position = 0;
       //Sets QR code image as result
       args.ImageStream = barcodeImage;
   }
}

7. Use the following code example to get the data to perform mail merge.
   C#

private static DataTable GetDataTable()
{
   //Creates new DataTable instance 
   DataTable table = new DataTable();
   //Add columns in DataTable
   table.Columns.Add("Name");
   table.Columns.Add("Website");

   //Add record in new DataRow
   DataRow row = table.NewRow();
   row["Name"] = "Google";
   row["Website"] = "http://www.google.com";
   table.Rows.Add(row);
   return table;
}
