How do I write a code in C# to read the contents of a PDF file that contains a bar code?

Thanks for Write On Pdf . I read this answers on Stack Overflow Here it is.- DataMatrix is a C# library that can decode barcodes from image files and I believe it can read them from PDFs too. Here is an example of usage. private string DecodeText(string sFileName) { DmtxImageDecoder decoder = new DmtxImageDecoder ; System.Drawing.Bitmap oBitmap = new System.Drawing.Bitmap(sFileName); List oList = decoder.DecodeImage(oBitmap); StringBuilder sb = new StringBuilder ; sb.Length = 0; foreach (string s in oList) { sb.Append(s); } return sb.ToString ; } You pass in an image filename and it will decode the barcode and return the string. If DataMatrix does not read from PDFs, then you'll have to also download iTextSharp which is a library for manipulating PDFs. Using iTextSharp, you can extract the barcode from the PDF, save it as an image, then use the function above to interpret the barcode. Note .- No credit goes to me. Thanks.

Write on PDF: All You Need to Know

I tried this solution, and it turned out to be broken. First I tried to open the PDF document in a Microsoft Reader. It does not create the “File:Microsoft PDF — MS Publisher”. It just gives me an error. After some hunting I found that this happens because Microsoft Reader must allow for PDF's with file extension .FM. If it doesn't, then I have to copy the filename of the PDF from the Windows Explorer window and then open the file in another program like Notepad to “Open with” the PDF file first. Thanks for that tip. Here's a little solution. Here's my current solution. Private String GetFileNameFromPDF(string filename) {string name = Environment. SpecialFolder. Path.Absolutest + filename; string name = Environment. SpecialFolder. SpecialPath. FileName; if, during a folder operation, the folder and the file that was removed must have been re-created, the operation fails. In order to get around this.
