.NET 邮件传送功能实现(smtp.qq.com)

记住端口和SMTP服务器地址（post:25,url:smtp.qq.com）

SendMail.cs

 3 using System.Net.Mail;
 4 using System.Net;

40                 _objMailMessage.To.Add(new MailAddress(desmail[i]));

43                 _objMailMessage.Body = body[i];
44                 try
45                 {
46                     _smtp.Send(_objMailMessage);
47                 }
48                 catch (Exception)
49                 {
50                     return false;
51                 }
52             }

53             return true;
54 
55         }
56 
57     }
58 }

web.config配置(像数据库那样配置)

<appSettings>
        <add key="UserMail" value="595806165@qq.com"/>
        <add key="PassWord" value="@zhangweiqq"/>
        <add key="mailsmtp" value="smtp.qq.com" />
        <add key="port" value="25"/>
    </appSettings>
