【.NET】发送Email

首先，在web.config的appSettings配置一下。

<appSettings>
    <add key="FromMail" value="xxx@163.com"/>
    <add key="MailDomain" value="smtp.163.com"/>
    <add key="MailServerUser" value="xxx"/>
    <add key="MailServerPWD" value="xxx"/>
</appSetting>

下面是类的方法，类名：Email

///发送找回密码Email
///发送注册成功Email
///发送Email方法
