sending mail including attachment from file upload control

Two Situations

1. You are running your website in Host.

2. You are running your website in Another machine(Client).


1.

Using different browsers you will get problem

(suppose chrome displays only filename insted of path.)


2.

eg: In your client machine filepath (C:\asdf.txt)
server you may not contain C:\asdf.txt file.


Solution:
Better thing upload file into Server.
and send from that path.
delete file after sent email.

(suggesition use different program for delete).

Copy file to server.
Attach to mail.
Send mail.
Delete file after sending.
use namespaces

using System.Net.Mime;
using System.Text;
using System.Net.Mail;
using System;

and method

private Boolean SendMailUsingGmail(String mailTo, String mailText, String attachmentFileWithPath)
 {
     Boolean sendMailResult;
     try
     {
         SmtpClient smtpServer = new SmtpClient();
         smtpServer.Credentials = new System.Net.NetworkCredential(mailFromId, mailFromPassword);
         smtpServer.Port = 25;
         smtpServer.Host = "smtp.gmail.com";
         MailMessage sampleMail = new MailMessage();
         sampleMail.From = new MailAddress(mailFromId);
         sampleMail.Subject = "Mail";
         string file = attachmentFileWithPath; //file path
         Attachment data = new Attachment(file, MediaTypeNames.Application.Zip);
         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.
         sampleMail.Attachments.Add(data);
         sampleMail.To.Add(mailTo);
         sampleMail.Body = mailText;
         smtpServer.Send(sampleMail);
         sendMailResult = true;
         return sendMailResult;
     }
     catch (Exception ex)
     {
         string exceptionString = ex.Message;
         sendMailResult = false;
         return sendMailResult;
     }
     finally
     {
     }

 }
