使用c＃从pdf文件中读取数据 [英] read data from pdf files using c#

问题描述

我有这个问题。我有5个PDF，有大约38,000个客观问题。所以我想创建一个导入这个问题的应用程序并将其保存到数据库中，然后为用户提供界面以选择具有四个目标的问题。我使用itextsharp从PDF中读取一个块，也逐行读取。阅读后的内容是分散的，我无法弄清楚我可以分割或区分问题和四个目标的顺序。有没有更好的方法可以从PDF导入数据？ PDF中的内容采用表格格式。



以下是pdf和结果字符串的快照。

I have this question. I have 5 PDFs having around 38,000 objective questions. So i want to make an application which imports this questions and save it into database and then give interface to the user for choosing question with four objective. I used itextsharp to read from PDFs as a chunk and also line by line. The content after reading is scattered and i cannot figure out a sequence by which i can split or differentiate between the question and the four objectives. Is there any better way by which I can import data from PDFs?? The content in PDFs is in tabular format.

Here is the snapshots of the pdf and the resulting string.
