aspx页面转为pdf 求助

Question

我最近在搞个小东西 里面有要求要把最后出来的报告转成pdf 
于是上网做了点搜索 找到了代码 但是似乎使用上有点问题using System;
using System.Data;
using System.Web;
using iTextSharp.text.pdf;
using iTextSharp.text;
using System.IO;
using System.Windows.Forms;
using System.Threading;namespace IMS
{
    public partial class Reports : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {        }
        protected void Button1_Click(object sender, EventArgs e)
        {
            CreatPdf();
        }
        private System.Drawing.Bitmap bitmap;
        private string url;
        private int w = 760, h = 900;
        public void setBitmap()
        {
            using (WebBrowser wb = new WebBrowser())
            {
                wb.Width = w;
                wb.Height = h;
                wb.ScrollBarsEnabled = false;
                wb.Navigate(url);                while (wb.ReadyState != WebBrowserReadyState.Complete)
                {
                    System.Windows.Forms.Application.DoEvents();
                }
                bitmap = new System.Drawing.Bitmap(w, h);
                wb.DrawToBitmap(bitmap, new System.Drawing.Rectangle(0, 0, w, h));
                wb.Dispose();
            }
        }
        private void CreatPdf()
        {
            Document doc = new Document(PageSize.A4, 9, 18, 36, 36);
            MemoryStream ms = new MemoryStream();
            try
            {
                PdfWriter writer = PdfWriter.GetInstance(doc, ms);
                writer.CloseStream = false;
                doc.Open();
                url = Server.MapPath("~/Reports.aspx");
                Thread thread = new Thread(new ThreadStart(setBitmap));
                thread.SetApartmentState(ApartmentState.STA);
                thread.Start();
                while (thread.IsAlive)
                    Thread.Sleep(100);
                bitmap.Save(Server.MapPath("t.bmp"));                iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance(bitmap, System.Drawing.Imaging.ImageFormat.Bmp);
                img.ScalePercent(75);//560 630
                doc.Add(img);
            }
            catch (Exception err)
            {
                throw new Exception(err.Message);
            }
            finally
            {
                doc.Close();
                using (FileStream fs = new FileStream(Server.MapPath("out.pdf"), FileMode.Create))
                {
                    ms.Position = 0;
                    byte[] bit = new byte[ms.Length];
                    ms.Read(bit, 0, (int)ms.Length);
                    fs.Write(bit, 0, bit.Length);
                }
                ViewPdf(ms);
            }
        }        private void ViewPdf(Stream fs)
        {
            Response.Clear();
            Response.AddHeader("Content-Disposition", "attachment;FileName=out.pdf");
            Response.AddHeader("Content-Length", fs.Length.ToString());
            Response.ContentType = "application/pdf";
            long fileLength = fs.Length;
            int size = 10240;
            byte[] readData = new byte[size];
            if (size > fileLength)
                size = Convert.ToInt32(fileLength);
            long fPos = 0;
            bool isEnd = false;
            while (!isEnd)
            {
                if ((fPos + size) >= fileLength)
                {
                    size = Convert.ToInt32(fileLength - fPos);
                    isEnd = true;
                }
                readData = new byte[size];
                fs.Position = fPos;
                fs.Read(readData, 0, size);
                Response.BinaryWrite(readData);
                Response.OutputStream.Flush();
                fPos += size;
            }
            fs.Close();
            Response.OutputStream.Close();
            Response.End();
            Response.Close();
        }    }
}
在按了按钮以后 打印的pdf out.pdf显示内容为
The XML page cannot be displayed名称已无效字符开头 等等请问下是为什么 如何解决 谢谢各位了

PDF在线阅读器，你看看能用不上

Answer 2

呃我是想要把Report这个动态的页面内容截取成图片然后转到一个pdf文件里面
因为可能要用到打印或者email用 貌似和阅读器没什么关系吧-。-

Answer 3

我知道有很多的代码都做了这个
我想知道的是我的应用是不是出问题了 因为pdf是能生成的 只是截取的网页图片不是页面该有的图 
想知道错在哪里了 
感谢~
