Since .NET classes don’t natively support PDF files you need a toolkit that can handle PDF files. - If the file is searchable PDF files you can parse the PDF pages and get the text object from it. Then you read these text objects as string and put them in a list and count the frequency of any word you want. - If the PDF file is not searchable (PDF pages are consist of images) then you need to OCR the PDF file and retrieve the text. Then count the frequency of any word you want. LEADTOOLS has PDF parser and OCR features and you can check these features in their online demo. https://demo.leadtools.com/JavaScript/DocumentViewer/index.html

Hi i'd suggest that you extract text from PDF and save as a .txt file and then count number of words in the .txt file.
