How can I attach a file to an email? - asp.net

Question

I am working on a project that has to send an email with an attachment. I have achieved sending mail, but I don't know how to attach an excel file.
Could someone point me in the right direction? Here's my code so far:
private void sendmail(string Tomailid, string name)
{
MailMessage mail = new MailMessage();
mail.From = new MailAddress("ehsimsemail#gmail.com");
mail.To.Add(Tomailid);
mail.Subject = "Test Mail";
StringBuilder sb = new StringBuilder();
sb.Append("Dear ");
sb.Append(string.Format("{0} ", name));
//sb.Append("Yuvaraj");
sb.Append(Environment.NewLine);
sb.Append(Environment.NewLine);
sb.Append("UCR No : ");
sb.Append("3256987");
sb.Append(" ");
sb.Append("HAS BEEN SENT FOR YOUR REVIEW AND APPROVAL");
sb.Append(Environment.NewLine);
sb.Append(Environment.NewLine);
sb.Append("For action, Please click Here");
sb.Append(Environment.NewLine);
sb.Append("This is a automatic generated report from Advanced Incident Management System (EHS-IMS). Please do not reply to this mail.");
sb.Append(Environment.NewLine);
sb.Append(Environment.NewLine);
sb.Append("Thanks & Regards,");
sb.Append(Environment.NewLine);
sb.Append("EHSIMS TEAM");
mail.Body = sb.ToString();
SmtpClient SmtpServer = new SmtpClient();
SmtpServer.Host = "smtp.gmail.com";
SmtpServer.Port = 587;
SmtpServer.EnableSsl = true;
SmtpServer.Credentials = new System.Net.NetworkCredential("ehsimsemail#gmail.com", "ehsims123");
SmtpServer.Send(mail);
}

Answer 1

That is so easy. So much material available on Internet.
Have a look at this link :
http://msdn.microsoft.com/en-us/library/system.net.mail.mailmessage.attachments.aspx
Short Code :
Attachment data = new Attachment(file, MediaTypeNames.Application.Octet);
// Add time stamp information for the file.
ContentDisposition disposition = data.ContentDisposition;
disposition.CreationDate = System.IO.File.GetCreationTime(file);
disposition.ModificationDate = System.IO.File.GetLastWriteTime(file);
disposition.ReadDate = System.IO.File.GetLastAccessTime(file);
// Add the file attachment to this e-mail message.
message.Attachments.Add(data);

Answer 2

You have to attach the file to your message.
mail.Attachments.Add(New Attachment(pathToExcelFile))
where pathToExcelFile is the file path to the file you want to send.
Make sure you have access rights to the file.
see the following for more information:

protected void btnSendMail_Click(object sender, EventArgs e)
{
string to = "reciever#gmail.com";
string from = "frommail#gmail.com";
string subject = "Mail Subject";
string body = "Mail Message";
MailMessage msgObj = new MailMessage();
msgObj.To.Add(to);
msgObj.Subject = subject;
msgObj.Body = body;
msgObj.IsBodyHtml = true;
msgObj.Attachments.Add(new Attachment(#"D:\sample.xlx"));
MailAddress objMail = new MailAddress(from, "emailCampaign", System.Text.Encoding.UTF8);
msgObj.From = objMail;
SmtpClient smtp = new SmtpClient();
smtp.Port = 587;
smtp.Host = "smtp.gmail.com";
smtp.Credentials = new System.Net.NetworkCredential(from, "password");
smtp.EnableSsl = true;
smtp.Send(msgObj);
}
