tried sending email with attachment,

just that it could not send the attachment but only the email

error :
System.IO.IOException: The process cannot access the file 'C:..\Websites\SendEmailwithAttachment\timesheet.xlsx' because it is being used by another process.
i guess this works:

eventhough it is checked from the task manager it is not running there,

          
            var smtp = new SmtpClient
            {
                Host = "smtp.gmail.com",
                Port = 587,
                EnableSsl = true,
                DeliveryMethod = SmtpDeliveryMethod.Network,
                UseDefaultCredentials = false,
                Credentials = new NetworkCredential("asdasd@gmail.com", "pwd"),
            };
            using (var message = new MailMessage("sadada@gmail.com", "sadsads@gmail.com")
            {
                Subject = "sadsasdaad",
                Body = "assadsadsada",

                

                

            })
            {

             //   string strFileName = null;

                if (inpAttachment2.PostedFile != null)
                {
                    HttpPostedFile attFile = inpAttachment2.PostedFile;
                    int attachFileLength = attFile.ContentLength;
                    if (attachFileLength > 0)
                    {
                        strFileName = Path.GetFileName(inpAttachment2.PostedFile.FileName);
                        inpAttachment2.PostedFile.SaveAs(Server.MapPath(strFileName));

                        Attachment attach = new Attachment(Server.MapPath(strFileName));

                        //MailAttachment attach = new MailAttachment(Server.MapPath(strFileName));
                        message.Attachments.Add(attach);
                        attach.Dispose();
                        //    attach2 = strFileName;
                    }
                }

                smtp.Send(message);
                message.Dispose();
            }

Hi doramail05,

Your problem seems to be caused by not released memory stream;

using (Attachment data = new Attachment("FileName",  MediaTypeNames.Application.Octet))
{
    // 1. Adding attachment to the e-mail message
    // 2. Sending out the e-mail message
}


The using statement will ensure that the Dispose method is called when the object gets out of the scope.

Also calling Dispose on the SmtpClient, doesn't call it on the Attachments.

Hope this will help you.
