如何使用ABCPdf.NET工具从PDF文件中提取文本的内容？

How to use the ABCPdf.NET tool to extract the content texts from a PDF file?

我试过了gettext方法，但不提取的内容：

I tried the GetText method but doesn't extract the contents:

var doc = new Doc();    

        var url = @".../FileName.pdf";

        doc.Read(url);

        string xmlContents = doc.GetText("Text");
        Response.Write(xmlContents);
        doc.Clear();
        doc.Dispose();

我的PDF有近1000字，但一个Gettext只返回4-5的话。我意识到它返回的第一页只有文字。

My pdf has almost 1000 words but the GetText only returns 4-5 words. I realized it returns only the texts of the first page.

因此​​，问题应该是如何提取从PDF文件的所有页面的文字？ - （改标题，以使其更清晰）

So the question should be "how to extract the text from all pages of a pdf file?" -(changed the Title to make it clearer).

谢谢

推荐答案

有关您的利益，是你！

 public string ExtractTextsFromAllPages(string pdfFileName)
    {
        var sb = new StringBuilder();

        using (var doc = new Doc())
        {
            doc.Read(pdfFileName);

            for (var currentPageNumber = 1; currentPageNumber <= doc.PageCount; currentPageNumber++)
            {
                doc.PageNumber = currentPageNumber;
                sb.Append(doc.GetText("Text"));
            }
        }

        return sb.ToString();
    }

如果您还没有网址，但有个字节，则：

if you don't have the url but have the bytes, then:

public string ExtractTextsFromAllPages(Byte[] pdfBytes)
    {
        var sb = new StringBuilder();

        using (var doc = new Doc())
        {
            doc.Read(pdfBytes);

            for (var currentPageNumber = 1; currentPageNumber <= doc.PageCount; currentPageNumber++)
            {
                doc.PageNumber = currentPageNumber;
                sb.Append(doc.GetText("Text"));
            }
        }

        return sb.ToString();
    }
