                string myText = stringWrite.ToString().Replace("&", "&amp;");
                StringReader sr = new StringReader(myText.ToString());
                Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);

                string strPath = Request.PhysicalApplicationPath + "\\Temp\\WeeklyReport of " + Projname + ".pdf";
                PdfWriter writer = PdfWriter.GetInstance(pdfDoc, new FileStream(strPath, FileMode.Create));
                pdfDoc.Open();
                XMLWorkerHelper.GetInstance().ParseXHtml(writer, pdfDoc, sr);

                pdfDoc.Close();
                pdfDoc.Dispose();

                LblNoteMsg.Text = strPath;
                DateTime input = DateTime.Now;
                int delta = DayOfWeek.Monday - input.DayOfWeek;
                DateTime dats = DateTime.Now.AddDays(delta);
                //this week
                DateTime monday = input.AddDays(delta);
                string MonDate = monday.ToShortDateString();
                DateTime sat = monday.AddDays(5);
                string SatDate = sat.ToShortDateString();
                StreamReader r = new StreamReader(Server.MapPath("~/WeeklyMail.txt"));
                string body = r.ReadToEnd();
                MailMessage Msg = new MailMessage();
                string MailId = txtMailId.Text;
                foreach (string ss in MailId.Split(",".ToCharArray()))
                {
                    if (string.IsNullOrEmpty(ss) == false)
                    {
                        Msg.To.Add(new MailAddress(ss));
                    }
                }


                Msg.Subject = "Weekly status Report";
                Msg.Body = body;
                Msg.IsBodyHtml = true;
                Msg.Attachments.Add(new Attachment(strPath));

                SmtpClient MailServer = new SmtpClient();
                try
                {

                    MailServer.Send(Msg);

Have you tried to assign new FileStream(strPath, FileMode.Create) to a separate varaible and then call either Close() or Dispose() on it when you are done writing? — Denis Yarkovoy, Jun 08 '15 at 05:25

In below code you can add some timestamp to file name so that different files get created.

string strPath = Request.PhysicalApplicationPath + "\\Temp\\WeeklyReport of " + Projname + ".pdf";

To

string strPath = Request.PhysicalApplicationPath + "\\Temp\\WeeklyReport of " + Projname + DateTime.Now.ToString("dd-MM-yyyy_HH:mm:ss") +".pdf";

I have changed file name by adding date and time.

string strPath = Request.PhysicalApplicationPath + "\\Temp\\WeeklyReport of " + Projname + DateTime.Now.ToString(" dd-MM-yyyy_HH-mm-ss") + ".pdf";
