的问题

我工作上有它的应用程序。 我使用pdf格式的文件,以重置的密码和价值观pdf存储为key-value(电子邮件:[email protected],通过:11111).

我想要做的:

阅读的PDF格式的文件线路线,并填写相应的文本框.

我做了什么:

public bool CreatePDF(string location, string email, string key)
    {
        if(location != "" && email != "" && key != "")
        {
            PdfWriter pdfwriter = new PdfWriter(location);
            PdfDocument pdf = new PdfDocument(pdfwriter);
            Document document = new Document(pdf);
            Paragraph fields = new Paragraph("Email: "+email + "\n" + "Secret Key: "+key);
            document.Add(fields);
            document.Close();
            return true;
        }            
        else
        {
            return false;
        }
    }

    public string ReadPDF(string location)
    {
        var pdfDocument = new PdfDocument(new PdfReader(location));
        StringBuilder processed = new StringBuilder();
        var strategy = new LocationTextExtractionStrategy();
        string text = "";
        for (int i = 1; i <= pdfDocument.GetNumberOfPages(); ++i)
        {
            var page = pdfDocument.GetPage(i);
            text += PdfTextExtractor.GetTextFromPage(page, strategy);
            processed.Append(text);
        }
        return text;
    }
}

谢谢你在前进伙计们. 任何建议CreatePDF也是受欢迎的。

        line = text + "&";            
        string[] newLines = line.Split('&'); 
        textBox1.Text = newLines[0].Split(':')[1].ToString(); 
        textBox2.Text = newLines[0].Split(':')[2].ToString();
