ASP.NET 2.0发送Smtp电子邮件真是麻烦.....搜索了好多资料(163,QQ,Sina,126)...都不成功....最后找到一个还算正常的..但就是发送不出....然后又找到另一个....两个结合起来就成功了....－　－|| ....

    // 发送Email  
    public static void SendSMTPEMail()
    {
        MailMessage message = new MailMessage("发送人邮箱", "收件人邮箱");
        message.Subject = "邮件标题";
        message.Body = "邮件内容";

        message.SubjectEncoding = Encoding.GetEncoding("gb2312");
        message.BodyEncoding = Encoding.GetEncoding("gb2312");
        message.IsBodyHtml = true;
        message.Priority = MailPriority.Normal;
        SmtpClient clint = new SmtpClient("smtp.gmail.com 邮箱服务器");
        clint.UseDefaultCredentials = false;
        clint.EnableSsl = true;
        clint.Credentials = new System.Net.NetworkCredential("[email protected] 邮箱", "邮箱密码");

        clint.DeliveryMethod = SmtpDeliveryMethod.Network;
        clint.Send(message);
        message.Dispose();
    }

    public static void Main()
    {
        SendSMTPEMail();
    }
}

        gmail的邮件发送成功率高,所以推荐使用smtp.gmail.com ,反正现在gmail申请已经不需要邀请了,还是蛮方便的吧
