C# System.Net.Mail.MailMessage 发邮件

上篇文化在哪个可以看到使用 System.Web.Mail.MailMessage 发邮件时会提示

，提供用于构造电子邮件的属性和方法。建议使用的替代项：System.Net.Mail，The recommended alternative is System.Net.Mail.MailMessage ，因此，我们新建控制台Console项目，然后添加 System.Net引用

代码如下：

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Globalization;
using System.IO;
//using System.IO.Pipes;
using System.Net;
using System.Net.Mail;
using System.Reflection;
using System.Text;
using System.Text.RegularExpressions;
 
namespace LongtengSupremeConsole
{
    class Program
    {        
        static void Main(string[] args)
        {
             System.Net.Mail.MailMessage mm = new System.Net.Mail.MailMessage();
            //mm.Sender = new MailAddress("mail@aliyun.com", "linjie");
            mm.From = new MailAddress("test@aliyun.com", "123");//发送方
            mm.To.Add(new MailAddress("test@qq.com", "456"));//接受方
            mm.CC.Add(new MailAddress("test@163.com", "123789"));//抄送方，CC就是carbon copy，副本，及抄送的意思
            mm.Subject = "Hello!";//主题
            mm.Body = "Hello. Here's the myphoto!";//内容
            mm.IsBodyHtml = false;//是否使用html格式
            mm.Priority = MailPriority.High;//优先级
            Attachment a = new Attachment("myphoto.jpg", System.Net.Mime.MediaTypeNames.Image.Jpeg);//附件
            mm.Attachments.Add(a);
 
            SmtpClient client = new SmtpClient();//smtp客户端
            client.Host = "smtp.aliyun.com";//服务器主机
            client.DeliveryMethod = SmtpDeliveryMethod.Network;//发送方式
            client.Port = 25;//端口
            client.Credentials = new NetworkCredential("test@aliyun.com", "***");//用户名和密码
            client.Send(mm);
            Console.WriteLine("邮件发送完成!!");
            Console.ReadKey();
        }
    }
}
