整理一下，在.NET中发送邮件的一个方法，代码如下：
1 public static string Net_Email(string strSendto, string strCC, string strBCC, string strMailContent, string strMailTitle, string[] strMailAttachMent, string strMailFormat, string strServiceTeam) 2 { 3 ????try 4 ????{ 5 ????????MailMessage mMail = new MailMessage(); 6 ????????using (mMail) 7 ????????{ 8 ????????????strMailContent = strMailContent.Replace("<br>\n", "<br>"); 9 ????????????string[] ListTo = strSendto.Split(‘;‘);10 ????????????for (int i = 0; i < ListTo.Length; i++)11 ????????????{12 ????????????????if (ListTo[i].Equals("")) continue;13 ????????????????mMail.To.Add(ListTo[i]);14 ????????????}15 ????????????string[] ListCC = strCC.Split(‘;‘);16 ????????????for (int i = 0; i < ListCC.Length; i++)17 ????????????{18 ????????????????if (ListCC[i].Equals("")) continue;19 ????????????????mMail.CC.Add(ListCC[i]);20 ????????????}21 ????????????string[] ListBCC = strBCC.Split(‘;‘);22 ????????????for (int i = 0; i < ListBCC.Length; i++)23 ????????????{24 ????????????????if (ListBCC[i].Equals("")) continue;25 ????????????????mMail.Bcc.Add(ListBCC[i]);26 ????????????}27 ????????????string[] strMailFrom = strServiceTeam.Split(‘;‘);28 ????????????mMail.From = strMailFrom[0].IndexOf("@", StringComparison.Ordinal) > 1 ? new MailAddress(strMailFrom[0]) : new MailAddress("xxxxx@xxx.com.cn");29 ????????????mMail.Body = strMailContent;30 ????????????mMail.Subject = strMailTitle;31 ????????????mMail.IsBodyHtml = strMailFormat == "";32 ????????????for (int i = 0; i < strMailAttachMent.Length; i++)33 ????????????{34 ????????????????string strFJ = strMailAttachMent[i] + "";35 ????????????????if (strFJ.Length > 0)36 ????????????????{37 ????????????????????mMail.Attachments.Add(new Attachment(strFJ));38 ????????????????}39 ????????????}40 ????????????SmtpClient smtp = new SmtpClient();41 ????????????smtp.Host = "10.10.10.10";42 ????????????smtp.Credentials = new NetworkCredential("emailcn", "123");43 ????????????smtp.DeliveryMethod = SmtpDeliveryMethod.Network;44 ????????????smtp.Send(mMail);45 ????????????return "1";46 ????????????}47 ????????}48 ????catch (Exception ex)49 ????{50 ????????return ex.Message;51 ????}52 } ???????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, "", "")
