使用iTextSharp获取PDF页面大小

Question

I have a PDF document that I just received via file upload (InputFile).

I'd like to use iTextSharp to check it's page size before proceeding. For example, the size of a pdf when you go to file > Properties > Description Tab > Page Size (in acrobat).

Any advice on how I can do that?

THANKS!

You need to read the pdf from your input stream (m).

PdfReader reader = new PdfReader(m);
// Page size
Rectangle pagesize = reader.GetPageSize(1);
