使用C#完成QQ发送邮件（简单使用）

 

 

    class QQEmail {
        public bool IsSetEmail(string FromAddress, string ToAddress, string Message,string Pwd) {
            

            MailAddress Address = new MailAddress(FromAddress);//
            MailMessage mail = new MailMessage();//
            mail.SubjectEncoding = System.Text.Encoding.UTF8;
            mail.Subject = "这是" + FromAddress + "发送的一段信息：";
            mail.BodyEncoding = System.Text.Encoding.UTF8;
            mail.Body =Message;//
            mail.IsBodyHtml = true;
            
            mail.Priority = System.Net.Mail.MailPriority.Low;
            mail.To.Add(ToAddress);//
                 
            mail.From = Address;

            SmtpClient smtp = new SmtpClient("smtp.qq.com",25);//smtp支持的服务器是smtp.qq.com，服务器端口是25,587也行

            smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
            smtp.EnableSsl = true;//
            smtp.UseDefaultCredentials = false;
            smtp.Credentials = new System.Net.NetworkCredential( FromAddress,Pwd);//切记这两个数据一定要填对
            
            try {
                smtp.Send(mail);
                return true;
            }catch (Exception ex) {
                System.Windows.Forms.MessageBox.Show(ex.Message);
                return false;
            }
        }
    }
}
