阅读PDF文件使用iTextSharp的 [英] Reading PDF File Using iTextSharp

问题描述

我使用C＃作为编程平台和 iTextSharp的阅读PDF内容。我用下面的代码阅读PDF内容，但现在看来，这每页读取。

I'm using C# as programming platform and iTextSharp to read pdf content. I have used the below code to read pdf content but it seems it read per page.

        public string ReadPdfFile(object Filename)
        {

            string strText = string.Empty;
            try
            {
                PdfReader reader = new PdfReader((string)Filename);

                for (int page = 1; page <= reader.NumberOfPages; page++)
                {
                    ITextExtractionStrategy its = new iTextSharp.text.pdf.parser.SimpleTextExtractionStrategy();
                    String s = PdfTextExtractor.GetTextFromPage(reader, page, its);

                    s = Encoding.UTF8.GetString(ASCIIEncoding.Convert(Encoding.Default, Encoding.UTF8, Encoding.Default.GetBytes(s)));
                    strText = strText + s;

                }
                reader.Close();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
            return strText;
        }

谁能帮我如何，我可以写一个读码每行PDF内容？

Can anyone help me on how can I write a code reading pdf content per line?

推荐答案

试试这个，改用的 LocationTextExtractionStrategy 的 SimpleTextExtractionStrategy
到文本返回，将增加新的行字符。然后你可以使用 strText.Split（'\\\
'）来的文字分成的String [] 和使用它在每行的基础。

Try this, use the LocationTextExtractionStrategy instead of the SimpleTextExtractionStrategy it will add new line characters to the text returned. Then you can use strText.Split('\n') to split your text into a string[] and consume it on a per line basis.
