阅读pdf页面的书签c＃ [英] Reading the Bookmark of a pdf page c#

问题描述

我正在尝试使用iTextSharp.text.pdf获取特定pdf页面的书签信息，我找到了如何在pdf中获取书签的集合，但我想只获取特定页面在pdf中，这是我的entayer代码pdf：



public void ExportBookmarksToXml（string SourcePdfPath，string xmlOutputPath，string Password =）

< pre lang =c＃> {

PdfReader reader = new PdfReader（SourcePdfPath，new System.Text.ASCIIEncoding（）。GetBytes（Password））;

IList< Dictionary< string，object>> bookmarks = SimpleBookmark.GetBookmark（reader）;

using（MemoryStream memoryStream = new MemoryStream（））

{

SimpleBookmark.ExportToXML（bookmarks， memoryStream，ISO8859-1，true）;

//MessageBox.Show（bookmarks [0] .Values.ToString（））;

File.WriteAllBytes（xmlOutputPath ，memoryStream.ToArray（））;

}

}< / pre>我需要这个，因为我想知道每个书签多少页和多少空白它拥有的页面。



谢谢！

File.WriteAllBytes(xmlOutputPath, memoryStream.ToArray());
}
}</pre>I need this, because I want to know for every bookmark how many pages and how many blank pages it has.

推荐答案

推荐的解决方案是：

What you can do right now is to create a function that returns a hashtable or a dictionary with the file names (string) being the keys and the pages to extract (integer array) being the values. Once you have this hashtable/dictionary, you can modify the ExtractPdfPage sub such that it will create a single new pdf file and then loop trhu the hashtable/dictionary to extract the pages and add them o the output pdf. It's just a matter of setting up the loop right such that in each loop, you read an entry and extract pages from that file.
