asp.net 发送邮件,带附件

以下是最近在做一个网站时我写的一个asp.net发送邮件的方法,放在类库中,可以随时拿来用.这个方法中,邮件的附件不需要先上传到服务器再发送,而是直接从你选择的路径中拿来发送

        /// <summary>
        /// 發送edm郵件,可以附加附件
        /// </summary>
        /// <param name="StrTo">收件人地址</param>
        /// <param name="toDisplayName">收件人名稱</param>
        /// <param name="strFrom">發件人地址</param>
        /// <param name="fromDisplayName">發件人名稱</param>
        /// <param name="StrBody">郵件內容</param>
        /// <param name="strSubject">郵件主題</param>
        /// <param name="path">附件路徑</param>
        /// <returns>返回是否發送成功</returns>
        public static bool SendEDMEmailBy47Server(string StrTo, string toDisplayName, string strFrom, string fromDisplayName, string StrBody, string strSubject,string path)
        {
           
            System.Net.Mail.MailAddress fromEmail = new System.Net.Mail.MailAddress(strFrom, fromDisplayName);//发件人的地址和发件人名称
            System.Net.Mail.MailAddress toEmail = new System.Net.Mail.MailAddress(StrTo, toDisplayName);//收件人地址和收件人名称
            System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage(fromEmail, toEmail);

            mail.Body = StrBody;
            mail.Subject = strSubject;
            mail.IsBodyHtml = true;
            mail.BodyEncoding = Encoding.UTF8;
            mail.Priority = System.Net.Mail.MailPriority.Normal;

            System.Net.Mail.SmtpClient smtpClient = new System.Net.Mail.SmtpClient();
            smtpClient.Host = "...";//这里设置成你的smtp主机名或者ip地址
            smtpClient.Port = 25;
            smtpClient.UseDefaultCredentials = false;
            smtpClient.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
            smtpClient.Credentials = new System.Net.NetworkCredential("xxx", "xxx");//你的用户名和密码

           

            //以下是邮件附件部分,path一般是从FileUpload控件中取~ 
            FileInfo fi;
            if (path != "")
            {
                fi = new FileInfo(path);
                if (fi.Exists)
                {
                    System.Net.Mail.Attachment firstatt = new System.Net.Mail.Attachment(path, System.Net.Mime.MediaTypeNames.Application.Octet);
                    System.Net.Mime.ContentDisposition disposion=new System.Net.Mime.ContentDisposition();
                    disposion.CreationDate=System.IO.File.GetCreationTime(path);
                    disposion.ModificationDate=System.IO.File.GetLastWriteTime(path);
                    disposion.ReadDate=System.IO.File.GetLastAccessTime(path);
                    mail.Attachments.Add(firstatt);
                }
            }
            try
            {
                smtpClient.Send(mail);
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
                return false;
            }
            return true;
        }
