打开PDF文件时，"PDFsharp无法处理Acrobat 6引入的PDF功能"错误 [英] 'PDFsharp cannot handle this PDF feature introduced with Acrobat 6' error while opening PDF file

问题描述

我使用PDFsharp(v1.32)合并多个PDF文件.我使用以下代码打开文档:

I use PDFsharp (v1.32) for merging several PDF files. I open documents using this code:

PdfDocument inputDocument = PdfReader.Open(pdfFilePath, PdfDocumentOpenMode.Import);

在打开一个文档(PDF版本1.5(Acrobat 6.x))时，我收到一个例外:

And while opening one document (with PDF version 1.5 (Acrobat 6.x)) I receive an exception:

PdfSharp.dll中发生了类型为'PdfSharp.Pdf.IO.PdfReaderException'的未处理异常 附加信息:无法处理iref流. PDFsharp的当前实现无法处理Acrobat 6引入的此PDF功能.

An unhandled exception of type 'PdfSharp.Pdf.IO.PdfReaderException' occurred in PdfSharp.dll Additional information: Cannot handle iref streams. The current implementation of PDFsharp cannot handle this PDF feature introduced with Acrobat 6.

我该怎么办?我需要合并所有文件，我不能只跳过它.我试图找到解决方案，但没有找到答案，或者只是来自PDFsharp Team的非常老的反馈，他们打算修复它".

What can I do with it? I need to merge all files, I cannot just skip it. I tried to find solution, but found not answered or just very old feedback from PDFsharp Team that they are going to "fix it".

推荐答案

使用2015年12月以后的PDFsharp 1.50 beta 3或更高版本.
