在web.config中设置多个SMTP设置？ [英] Setting multiple SMTP settings in web.config?

问题描述

我建立，需要动态/编程知道和发送电子邮件时使用不同的SMTP设置的应用程序。

I am building an app that needs to dynamically/programatically know of and use different SMTP settings when sending email.

我已经习惯了使用system.net/mailSettings的方法，但据我了解，只允许在同一时间（）一个SMTP连接定义，通过SmtpClient使用。

I'm used to using the system.net/mailSettings approach, but as I understand it, that only allows one SMTP connection definition at a time, used by SmtpClient().

不过，我需要更多是connectionStrings式的方法，在那里我可以拉基于键/名称的一组设置。

However, I need more of a connectionStrings-like approach, where I can pull a set of settings based on a key/name.

任何建议？我打开跳过tradintional SmtpClient / mailSettings的做法，我认为将不得不...

Any recommendations? I'm open to skipping the tradintional SmtpClient/mailSettings approach, and I think will have to...

推荐答案

我需要有在web.config不同的SMTP配置根据不同的环境：开发，分期和生产

I needed to have different smtp configurations in the web.config depending on the environment: dev, staging and production.

下面是我最终使用：

在web.config中：

In web.config:

<configuration>
  <configSections>
    <sectionGroup name="mailSettings">
      <section name="smtp_1" type="System.Net.Configuration.SmtpSection"/>
      <section name="smtp_2" type="System.Net.Configuration.SmtpSection"/>
      <section name="smtp_3" type="System.Net.Configuration.SmtpSection"/>
    </sectionGroup>
  </configSections>
  <mailSettings>
    <smtp_1 deliveryMethod="Network" from="[e-mail]">
      <network host="..." defaultCredentials="false"/>
    </smtp_1>
    <smtp_2 deliveryMethod="Network" from="[e-mail]">
      <network host="1..." defaultCredentials="false"/>
    </smtp_2>
    <smtp_3 deliveryMethod="Network" from="[e-mail]">
      <network host="..." defaultCredentials="false"/>
    </smtp_3>
  </mailSettings>
</configuration>

然后在code：

Then in code:

return (SmtpSection)ConfigurationManager.GetSection("mailSettings/smtp_1");
return (SmtpSection)ConfigurationManager.GetSection("mailSettings/smtp_2");
return (SmtpSection)ConfigurationManager.GetSection("mailSettings/smtp_3");
