MailHelper：

public class MailHelper
    {
        public bool SendMail(MailSender sender,out string errorMsg)
        {
            //声明一个Mail对象
            MailMessage mymail = new MailMessage();
            //发件人地址
            //如是自己，在此输入自己的邮箱
            mymail.From = new MailAddress(sender.SendAddress,sender.SendNickName,Encoding.UTF8);
            //收件人地址
            mymail.To.Add(new MailAddress(sender.ReceiveAddress));
            //邮件主题
            mymail.Subject = sender.Title;
            //邮件标题编码
            mymail.SubjectEncoding = Encoding.UTF8;
            //发送邮件的内容
            mymail.Body = sender.Content;
            //邮件内容编码
            mymail.BodyEncoding = Encoding.UTF8;
            //添加附件
            foreach (var attachment in sender.Attachments)
            {
                mymail.Attachments.Add(attachment);
            }
            
            //抄送到其他邮箱
            foreach (var str in sender.Cc)
            {
                mymail.CC.Add(new MailAddress(str));
            }
            
            //是否是HTML邮件
            mymail.IsBodyHtml = sender.IsBodyHtml;
            //邮件优先级
            mymail.Priority = sender.MailPriority;
            //创建一个邮件服务器类
            SmtpClient myclient = new SmtpClient();
            myclient.Host = sender.Host;
            //SMTP服务端口
            myclient.Port = sender.Port;
            //验证登录
            myclient.Credentials = new NetworkCredential(sender.Username, sender.Password);//"@"输入有效的邮件名, "*"输入有效的密码
            try
            {
                myclient.Send(mymail);
                errorMsg = "";
                return true;
            }
            catch (Exception ex)
            {
                errorMsg = ex.Message;
                return false;
            }
            
        } 

　　调用：

MailSender sender=new MailSender();
            sender.SendAddress = "***@***.com";
            sender.SendNickName = "辰晓晨";
            sender.ReceiveAddress = "***@***.com";
            sender.Host = "smtp.***.com";
            sender.Port = 25;
            sender.Username = "****@***.com";
            sender.Password = "******";
            sender.Title = "来自辰晓晨的邮件";
            sender.Content = "来自辰晓晨的邮件";
            sender.IsBodyHtml = false;
            sender.MailPriority=MailPriority.Normal;
            MailHelper.MailHelper mailHelper = new MailHelper.MailHelper();
            string errorMsg;
            if (mailHelper.SendMail(sender, out errorMsg))
            {
                Console.WriteLine("发送成功");
                
            }
            else
            {
                Console.WriteLine("发送失败:"+errorMsg);
                
            }
