Emails with blank attachments (PDF, DOC)

Hello Experts,
On our website a user can upload a file. That file is saved to our database (SQL) and then an email  sent with the uploaded file as an attachment.
When we test on the  dev server everything works fine (so there is no problem with the code).
When we test on the  prod server the email comes with attachment that is 64b and blank. Both servers have same configuration. The only difference is that prod server has SSL.
Please, help. We keep receiving blank attachment.
Thanks.

Are you facing this issue with all incomming emails (with attachement) or only emails coming from your application server?

Only the emails from the application server.

you probably lack some checks when the file gets uploaded, but you need to debug a little bit more :

log downloaded file sizes or take a look in the database. if i'm right we'll need to see the upload code. if not the problem would rather be on the sending part and we'll need that code and one message's source

Below is a code to upload and send the attachment.

//ASP code
<strong>Resume:</strong> Please upload your resume </strong>. 
<asp:FileUpload ID="FileCv" runat="server" />
…..
<asp:LinkButton ID="LBtnSubmit" runat="server" Text="Submit" CssClass="btn" OnClick="LBtnSubmit_Click" />
           

//**********************************************************************
//CS code
protected void LBtnSubmit_Click(object sender, EventArgs e)
        {
            try
            {
                //save resume to db
               UploadResumeToDB();
               SendSEmail();
            }
            catch (Exception ex)
            {
                Response.Write(ex);
                LtError.Text = "An error has occurred while attempting to submit our    application. Please try again later, or contact a staff member if the error persists. <span style=\"display: none;\">" + ex.ToString() + "</span>";
            }
        }

private void UploadResumeToDB()
{
            String fileName = "";

            if (FileCv.HasFile && FileCv.PostedFile != null)
            {
                HttpPostedFile file = FileCv.PostedFile;
                fileName = FileCv.PostedFile.FileName;
                LetRes = new Byte[file.ContentLength];
                file.InputStream.Read(LetRes, 0, file.ContentLength);
            }

            //Save resume
            if (LetRes != null)
            {
                GDataAccess da = null;

                using (da = new GDataAccess(connString))
                {
                   //…. code that executes SP and saves file to DB no problem here. Everything is working.
                }
            }
        }


private void SendSEmail()
        {
          String emailTo = myEmail@nyc.org;

            String sb =”EmailText”;
         
            String uploadFileName = Path.GetFileName(FileCv.PostedFile.FileName);
            Attachment cv = new Attachment(FileCv.FileContent, uploadFileName);
            GUtility.SendEmail("NYC Notification", sb, emailTo, cv);
          }


//UTILITIES 

public class GUtility
    {
public static void SendEmail(String subject, String body, String emailTo, Attachment optionalAttachment)
        {
            Configuration configurationFile = WebConfigurationManager.OpenWebConfiguration("web.config");
            MailSettingsSectionGroup mailSettings = configurationFile.GetSectionGroup("system.net/mailSettings") as MailSettingsSectionGroup;
            SmtpClient smtp = new SmtpClient(mailSettings.Smtp.Network.Host);
            MailMessage email = new MailMessage();

            email.Subject = subject;

            email.Body = body;
            email.IsBodyHtml = true;

            if (optionalAttachment != null)
            {
                email.Attachments.Add(optionalAttachment);
            }
           email.To=emailTo;
           smtp.Send(email);
        }

how are you storing your  uploaded files?
are your storing file in database or storing a path to file in database?

i think the file name seems to get wrong path, try with server.Mappath
try the link given below
Sending Email with attachment in ASP.NET using SMTP Server
