c# - itextsharp和pdf

Question

我想每行读取一个 pdf 文件行，但我想保持他的原始格式

¿我可以用 itextsharp 做到这一点吗？

我使用下一个代码：

private void button1_Click(object sender, EventArgs e)
        {

            string text = string.Empty;
            string path = string.Empty;
            path = "C:\\Documents and Settings\\Rafael\\Desktop\\Imprimiendo\\Print1.pdf";
            PdfReader reader = new PdfReader(path);

            for (int page = 1; page <= reader.NumberOfPages; page++)
            {
                text = PdfTextExtractor.GetTextFromPage(reader, page);
                richTextBox1.Text = text;

            }
            reader.Close();
            return;
        }

谢谢，我真的需要你的帮助
