Depends on the file upload control you use. But it should have an event like Upload_Complete() or something where you can get access to the file. Then your code will likely be the same.

I won't write all of the code for you. See this for reference, https://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.fileupload(v=vs.110).aspx#saving_uploaded_files

The FileUpload Control does not pass you a file - it passes you a stream of bytes - so you need to look at your PdfReader Class constructor to see if there is an overload that takes a Stream, an array of bytes, or a string of data rather than a string path.
You can then convert the data appropriately and pass it to the constructor.

If the class only accepts a path to a file, then you will need to kludge round it and create a temporary file, write your data to do, open your PDF, process it, then close and delete the temporary file. Nasty, and prone to leaving large temporary documents "laying around" if anything goes wrong, so you'll want a mechanism for clearing those up as well...
