using Microsoft.AspNetCore.Mvc;
using MimeKit;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Mail;
using System.Threading.Tasks;
//SmtpClient smtpClient = System.Net.Mail.SmtpClient;
namespace emil.Controllers
{
    public class Get : Controller
    {
        public void xx() {

            //收件人邮箱
            string mailName = "[email protected]";
            //发送的标题
            string title = "测试数据";
            //发送的内容
            string bobyText = "吃鸡丁拌面!";
            // 邮件服务器smtp.qq.com表示qq邮箱服务器    
            string host = "smtp.qq.com";
            // 发送端账号   
            string userName = "[email protected]";
            // 发送端授权码，需要在邮箱获取授权码
            string pwd = "vtwsxdesafdobjab";
            MimeMessage message = new MimeMessage();
            //发件人
            message.From.Add(new MailboxAddress("T.Shiller", userName));
            //收件人
            message.To.Add(new MailboxAddress(title, mailName));
            //   message.To.Add(new MailboxAddress(title,mailName ));
           
            //标题
            message.Subject = title;
            //正文内容，发送
            message.Body = new BodyBuilder
            {
                HtmlBody = bobyText
            }.ToMessageBody();
            try
            {
                using (var client = new MailKit.Net.Smtp.SmtpClient())
                {
                    //Smtp服务器
                    client.Connect(host, 587, false);
                    //登录，发送
                    client.Authenticate(userName, pwd);
                    client.Send(message);
                    //断开
                    client.Disconnect(true);
                }

            }
            catch (Exception)
            {
                throw;
            }


        }
    }
}
