       bool result = false;

        string MailName = ConfigurationManager.AppSettings["MailName"].ToString();
        string MailPwb = ConfigurationManager.AppSettings["MailPwd"].ToString();

        MailMessage mailObj = new MailMessage();

        mailObj.Subject = "您的密碼";
        mailObj.BodyFormat = MailFormat.Html;
        mailObj.Body = "<h3>" + "aaa" + "您好.<br><br>" + "您的密碼為：" + "aaaaa" + "。<br><br>";
        //mailObj.BodyEncoding = System.Text.Encoding.Default;
        mailObj.BodyEncoding = System.Text.Encoding.UTF8;
        mailObj.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1"); //basic authentication
        mailObj.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", MailName); //set your username here
        mailObj.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", MailPwb); //set your password here
        //mailObj.BodyEncoding = System.Text.Encoding.;
        //mailObj.BodyEncoding = System.Text.Encoding.GetEncoding("GB2312");//郵件採用的編碼

 

        SmtpMail.SmtpServer = MailSmtp;
        try
        {
            SmtpMail.Send(mailObj);
            result = true;
        }
        catch (System.Exception ex)
        {
            result = false;
        }

錯誤產生的原因：
1.mail.BodyEncoding 的編碼格式不正確。
2.設定發送郵件的帳號密碼資訊不正確
3.設定發送郵件伺服器的SMTP地址不正確
上面三種情況都有可能造成發送郵件失敗，報亂碼異常。
