Hi Experts

I am trying to open a pdf document in a aspx page but i dont know what is the mistake i made in the following code.

   string Path = Request.QueryString["Path"];
        if (File.Exists(Path.Replace("pdf", "txt")))
        {
            FileStream fs = null;
            try
            {
                fs = File.Open(Path, FileMode.Open, FileAccess.ReadWrite, FileShare.None);
            }
            catch (IOException)
            {
            }
            bool canRead = fs.CanRead;
            if (canRead)
            {
                fs.Close();
                Response.Write("");
            }
        }
        else
            Response.Write("");

In the above code there are two problems
1) I could not show the pdf document on the page
2) In the else loop if the document doesnot exist then i need to display the message and close the current page.

Any ideas??????????

Hi karthik,

Try this...

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Net;
public partial class Default2 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
    ReadPdfFile();
    }

    private void ReadPdfFile()
    {
        string path = @"d:\a.pdf";
        WebClient client = new WebClient();
        Byte[] buffer = client.DownloadData(path);

        if (buffer != null)
        {
            Response.ContentType = "application/pdf";
            Response.AddHeader("content-length", buffer.Length.ToString());
            Response.BinaryWrite(buffer);
        }

    }
}

Thanks
