        string senderName = ConfigurationManager.AppSettings["From"].ToString();
        string mailServer = ConfigurationManager.AppSettings["SMTPServer"].ToString(); ;
        string senderEmailId = ConfigurationManager.AppSettings["SMTPUserName"].ToString();
        string password = ConfigurationManager.AppSettings["SMTPPasssword"].ToString();
        var fromAddress = new MailAddress(senderEmailId, senderName);
        var toAddress = new MailAddress(receiverEmailId, "Alen");
        string subject = "subject";
        string body = "body.";
        var smtp = new SmtpClient
        {
            Host = "smtp.gmail.com",
                    Port = 587,
                    EnableSsl = true,
                    DeliveryMethod = SmtpDeliveryMethod.Network,
                    Credentials = new NetworkCredential(fromAddress.Address, password)
        };
        using (var message = new MailMessage(fromAddress, toAddress)
        {
            Subject = subject,
            Body = body
        })
        {
            smtp.Send(message);
        }
    }
    catch (Exception ex)
    {
    }

Answer 1

您是否查看了MailMessage.Attachments属性(请参阅MSDN)？

// create attachment and set media Type
//      see http://msdn.microsoft.com/de-de/library/system.net.mime.mediatypenames.application.aspx
Attachment data = new Attachment(
                         "PATH_TO_YOUR_FILE", 
                         MediaTypeNames.Application.Octet);
// your path may look like Server.MapPath("~/file.ABC")
message.Attachments.Add(data);

Answer 2

Attachment使用文件名创建类的对象,并将其添加到消息的Attachments属性中

  Attachment attachment = new Attachment("file.ext");
  message.Attachments.Add(attachment);

public static bool SendMail(string strFrom, string strTo, string strSubject, string strMsg)
    {            
        try
        {                
            // Create the mail message
            MailMessage objMailMsg = new MailMessage(strFrom, strTo);

            objMailMsg.BodyEncoding = Encoding.UTF8;
            objMailMsg.Subject = strSubject;
            objMailMsg.Body = strMsg;
            Attachment at = new Attachment(Server.MapPath("~/Uploaded/txt.doc"));
            objMailMsg.Attachments.Add(at);
            objMailMsg.Priority = MailPriority.High;
            objMailMsg.IsBodyHtml = true;

            //prepare to send mail via SMTP transport
            SmtpClient objSMTPClient = new SmtpClient();
            objSMTPClient.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;
            objSMTPClient.Send(objMailMsg);
            return true;                
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }
