使用iTextSharp c#从PDF中逐行提取文本

Question

我需要运行一些分析,从PDF文档中提取数据.

使用iTextSharp,我使用该PdfTextExtractor.GetTextFromPage方法从PDF文档中提取内容,并在一个长行中返回给我.

有没有办法逐行获取文本,以便我可以将它们存储在数组中？这样我就可以逐行分析数据,这将更加灵活.

以下是我使用的代码:

       string urlFileName1 = "pdf_link";
        PdfReader reader = new PdfReader(urlFileName1);
        string text = string.Empty;
        for (int page = 1; page <= reader.NumberOfPages; page++)
        {
            text += PdfTextExtractor.GetTextFromPage(reader, page);
        }
        reader.Close();
        candidate3.Text = text.ToString();

Answer 1

    public void ExtractTextFromPdf(string path)
    {
        using (PdfReader reader = new PdfReader(path))
        {
            StringBuilder text = new StringBuilder();
            ITextExtractionStrategy Strategy = new iTextSharp.text.pdf.parser.LocationTextExtractionStrategy();

            for (int i = 1; i <= reader.NumberOfPages; i++)
            {
                string page = "";

                page = PdfTextExtractor.GetTextFromPage(reader, i,Strategy);
                string[] lines = page.Split('\n');
                foreach (string line in lines)
                {
                    MessageBox.Show(line);
                }
            }
        }
    }

Answer 2

尝试

 String page = PdfTextExtractor.getTextFromPage(reader, 2);
 String s1[]=page.split("\n");
