C# programming to read PDF files
This seems to be a rather difficult task, and perhaps you've already found references in web. If you have a PDF file and you don't know how to read data from it, you can refer to the following.
First of all, you need some dynamic libraries that can help you process PDF files. I'm using PDFBox. So, what is PDFBox? The official website describes PDFBox as an open source Java PDF library for processing PDF documents. It can create new PDF documents, process existing PDF documents, and extract content from documents. PDFBox also contains several command line utilities.
