.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>
", "<br>");
            string[] ListTo = strSendto.Split(';');
            for (int i = 0; i < ListTo.Length; i++)
            {
                if (ListTo[i].Equals("")) continue;
                mMail.To.Add(ListTo[i]);
            }
            string[] ListCC = strCC.Split(';');
            for (int i = 0; i < ListCC.Length; i++)
            {
                if (ListCC[i].Equals("")) continue;
                mMail.CC.Add(ListCC[i]);
            }
            string[] ListBCC = strBCC.Split(';');
            for (int i = 0; i < ListBCC.Length; i++)
            {
                if (ListBCC[i].Equals("")) continue;
                mMail.Bcc.Add(ListBCC[i]);
            }
            string[] strMailFrom = strServiceTeam.Split(';');
            mMail.From = strMailFrom[0].IndexOf("@", StringComparison.Ordinal) > 1 ? new MailAddress(strMailFrom[0]) : new MailAddress("xxxxx@xxx.com.cn");
            mMail.Body = strMailContent;
            mMail.Subject = strMailTitle;
            mMail.IsBodyHtml = strMailFormat == "";
            for (int i = 0; i < strMailAttachMent.Length; i++)
            {
                string strFJ = strMailAttachMent[i] + "";
                if (strFJ.Length > 0)
                {
                    mMail.Attachments.Add(new Attachment(strFJ));
                }
            }
            SmtpClient smtp = new SmtpClient();
            smtp.Host = "10.10.10.10";
            smtp.Credentials = new NetworkCredential("emailcn", "123");
            smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
            smtp.Send(mMail);
            return "1";
            }
        }
    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, "", "")
