在 ASP.NET 2.0 中发送邮件

2010-08-28 10:50:09来源：西部e网作者：

在 .net 2.0 中发送邮件将使用到新增的 SmtpClient 类，并且可以在配置文件中加入 mailSettings 元素来配置 smtp。下面以 asp.net 为例写的 demo.

在 web.config 文件添加
<system.net>
    <mailSettings>
        <smtp>
            <network host="localhost" port="25" userName="your username"
                password="your password"/>
        </smtp>
    </mailSettings>
</system.net>

发送简单的文本格式的邮件
