我的代码是，

Hi all,
i am facing problem in extracting text of pdf document paragraph wise, please help me out.

my code is,

private void ReadPdf(string _filePath)
        {
            PdfReader rd = new PdfReader(_filePath);
            int pageNumber = 1;
           // TextWriter oContent = TextWriter(Char);
            string oContent = "";
            while (pageNumber <= rd.NumberOfPages)
            {
                oContent += PdfString.STREAM.ToString();
                ++pageNumber;
            }
        }

我能读取pdf文本，但它逐行提取。但我想在段落中

in the above code i am able read the pdf text but it extracts line by line. but i want in paragraph wise

推荐答案

PdfReader reader = new PdfReader(path);
 StringWriter output = new StringWriter();
 for (int i = 1; i <= reader.NumberOfPages; i++)
 {
     Paragraph o = CreateSimpleHtmlParagraph(output.ToString());
     output.WriteLine(PdfTextExtractor.GetTextFromPage(reader, i, new SimpleTextExtractionStrategy()));
 }
