用ITextSharp.dl如何读取复杂的bookmarks

[hqwjohn]

        private void button1_Click(object sender, EventArgs e)
        {
            string s="";
            PdfReader pdfr = new PdfReader("d:\\sj.pdf");
            IList<Dictionary<string, object>> list = SimpleBookmark.GetBookmark(pdfr, pdfr.Catalog,true);
            foreach (Dictionary<string, object> i in list)
            {
                string title = (string)i["Title"];
                string[] pagenum = ((string)i["Page"]).Split(' ');
                s += title.Substring(0, title.Length - 1) + "  " + pagenum[0] + "\n";
            }
            richTextBox1.Text = s;
        }

ITextSharp.dll当中的SimpleBookmark只能读取简单的bookmarks

        
比如这种
        bookmark1
        bookmark2
        bookmark3
        bookmark4
        bookmark5
        bookmark6
如果复杂一点，比如这种，就不行，不知道到有没有解决办法？？
        bookmark1
            bookmark2
            bookmark3
        bookmark4
            bookmark5
        bookmark6

感谢你的回复，但是你的回答似乎没有针对我提的问题

c#使用itextsharp读取pdf文件的文本内容 public string ReadPdfFile(string fileName) { StringBuilder text = new StringBuilder(); if (File.Exists(fileName)) { PdfReader pdfReader = new PdfReader(fileName); for (int page = 1; page <= pdfReader.NumberOfPages; page++) { ITextExtractionStrategy strategy = new SimpleTextExtractionStrategy(); string currentText = PdfTextExtractor.GetTextFromPage(pdfReader, page, strategy); currentText = Encoding.UTF8.GetString(ASCIIEncoding.Convert(Encoding.Default, Encoding.UTF8, Encoding.Default.GetBytes(currentText))); text.Append(currentText); } pdfReader.Close(); } return text.ToString(); }
