.NET发送邮件的方法

整理一下，在.NET中发送邮件的一个方法，代码如下：

 public static string Net_Email(string strSendto, string strCC, string strBCC, string strMailContent, string strMailTitle, string[] strMailAttachMent, string strMailFormat, string strServiceTeam)
 {
     try
     {
         MailMessage mMail = new MailMessage();
         using (mMail)
         {
             strMailContent = strMailContent.Replace("<br>\n", "<br>");
             string[] ListTo = strSendto.Split(';');
             for (int i = ; i < ListTo.Length; i++)
             {
                 if (ListTo[i].Equals("")) continue;
                 mMail.To.Add(ListTo[i]);
             }
             string[] ListCC = strCC.Split(';');
             for (int i = ; i < ListCC.Length; i++)
             {
                 if (ListCC[i].Equals("")) continue;
                 mMail.CC.Add(ListCC[i]);
             }
             string[] ListBCC = strBCC.Split(';');
             for (int i = ; i < ListBCC.Length; i++)
             {
                 if (ListBCC[i].Equals("")) continue;
                 mMail.Bcc.Add(ListBCC[i]);
             }
             string[] strMailFrom = strServiceTeam.Split(';');
             mMail.From = strMailFrom[].IndexOf("@", StringComparison.Ordinal) >  ? new MailAddress(strMailFrom[]) : new MailAddress("[e-mail]");
             mMail.Body = strMailContent;
             mMail.Subject = strMailTitle;
             mMail.IsBodyHtml = strMailFormat == "";
             for (int i = ; i < strMailAttachMent.Length; i++)
             {
                 string strFJ = strMailAttachMent[i] + "";
                 if (strFJ.Length > )
                 {
                     mMail.Attachments.Add(new Attachment(strFJ));
                 }
             }
             SmtpClient smtp = new SmtpClient();
             smtp.Host = "10.10.10.10";
             smtp.Credentials = new NetworkCredential("emailcn", "");
             smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
             smtp.Send(mMail);
             return "";
             }
         }
     catch (Exception ex)
     {
         return ex.Message;
     }
 }        

调用方式：

组装邮件内容的时候，是调用一个html模板，将其中的标签内容进行替换

var strFileCn = File.ReadFile(MapPath("order_model.html"), "utf-8");
strFileCn = strFileCn.Replace("#orderid#", orders.orderid);
strFileCn = strFileCn.Replace("#username#", orders.username);

var att = new string[1];
att[0] = "";

Net_Email(strsendto, strcc, "", strFileCn, "商品订购单Order sheet.",att, "", "")
