Hi,
I am Opening a simple  txt file in Asp.net.It is opening the file but at the end of the file
It is adding all the source code of my page.

Here's the code                    

                            TextBox1.Text = CommonFunction.ToString(Session["FilePath"]);
                            string lfilepath = TextBox1.Text;
                            string pat = @"\\(?:.+)\\(.+)\.(.+)";
                            Regex r = new Regex(pat);
                            //run
                            Match m = r.Match(lfilepath);
                            string lfile_ext = m.Groups[2].Captures[0].ToString();
                            string lfilename = m.Groups[1].Captures[0].ToString();
                            string lfile = lfilename + "." + lfile_ext;

                            //string path = Server.MapPath((".\\UploadedFile\\1\\ABCDSummary.txt"));
                            string path = CommonFunction.ToString(Session["FilePath"]);

                            FileStream fs = new FileStream(path, FileMode.Open);
                            //fs = File.Open(path, FileMode.Open);
                            byte[] bytBytes = new byte[fs.Length + 1];
                            fs.Read(bytBytes, 0, (int)fs.Length);
                            fs.Close();                        
                            Response.AddHeader("Content-Disposition", "attachment; filename=" + lfile);
                            Response.ContentType = "APPLICATION/OCTET-STREAM";
                            Response.Flush();
                            Response.BinaryWrite(bytBytes);
                           

after fs.Close()

..

Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=" + lfile);
Response.ContentType = "APPLICATION/OCTET-STREAM";
Response.BinaryWrite(bytBytes);
Response.Flush();
Response.End();

Thanks......
