But I also have another problem.

I want to send the uploaded files as an attachment to an email. 

Hi,

Thanks for your back.

For attaching email a file dirrectly from the FileUpload control, please chec below code.

private bool SendMail()
 {
 try
 {
 
/* Create a new blank MailMessage */
 MailMessage mailMessage = new MailMessage();
 
mailMessage.From = txtTo.Text;
 
mailMessage.To = "your email";
 
mailMessage.Subject = txtSubject.Text ;
 
msgMail.Body = txtMessage.Text ;
 
/* We use the following variables to keep track of
 attachments and after we can delete them */
 
string attach1 = null;
 
/*strFileName has a attachment file name for attachment process. */
 
string strFileName = null;
 
if (FileUpload1.PostedFile != null)
 {
 /* Get a reference to PostedFile object */
 HttpPostedFile attFile = FileUpload1.PostedFile;
 
/* Get size of the file */
 int attachFileLength = attFile.ContentLength;
 
/* Make sure the size of the file is > 0 */
 if (attachFileLength > 0)
 {
 /* Get the file name */
 strFileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
 
/* Save the file on the server */
 FileUpload1.PostedFile.SaveAs(Server.MapPath(strFileName));
 
/* Create the email attachment with the uploaded file */
 MailAttachment attach = new MailAttachment(Server.MapPath(strFileName));
 
/* Attach the newly created email attachment */
 mailMessage.Attachments.Add(attach);
 
/* Store the attach filename so we can delete it later */
 attach1 = strFileName;
 }
 
/* Set the SMTP server and send the email with attachment */
 SmtpMail.SmtpServer = ("your smtp");
 
SmtpMail.Send(mailMessage);
 
/* Delete the attachements if any */
 if (attach1 != null)
 {
 File.Delete(Server.MapPath(attach1));
 }
 }
 
return true;
 }
 catch (Exception ex)
 {
 return false;
 }
 }
 
protected void btn_Send_Click(object sender, EventArgs e)
 {
 bool TrueOrFalse = SendMail();
 
if ((TrueOrFalse == true))
 {
 Response.Redirect("~/MailSent.aspx");
 }
 else
 {
 Label1.Text = "Try again";
 }
 }

There is example for this, please follow below article.
