You posted code that has neither to do with Hashtable nor Dictionary, please show the line of code that throws the specified exception.

Thanks for your cooperation.

foreach (KeyValuePair<string,> kvp in infodict)

Where did you get the PdfReader class from? Most probably, either the PdfReader constructor or the GetPageSize method is throwing the error. If you have the source code for the PdfReader class, you can try debugging the error.

Honestly, the error message tells you exactly what is wrong. Something is returning a Hashtable, and you are trying to assign it to a typed Dictionary. You are wasting your time and ours by asking this type of question here – a little knowledge and you could solve this kind of thing in far less than 25 minutes.

From your comment it appears this is quite an old reader class that returns Info as a Hashtable. So don't try to assign it to a type it isn't compatible with!
