Can a pdfbox or itextsharp or pdfsharp reads corrupted pdf file

I recently downloaded pdf libraries ( pdfbox, pdfsharp, itextsharp), and I am trying to figure out can i parse corrupted pdf files with in Asp.Net. which lib is best开发者_C百科 for reading corrupted pdf file.

If the file is corrupt, there is no guaranteed way to read it. You cannot know which part or parts are corrupt. You could use a hex editor utility and manually inspect which parts might be corrupted, but there is no way to use any of the libraries you mentioned to open a corrupted file. They all work off the PDF specification, which assumes a valid PDF file.
