我正在尝试调整.Net网站中的邮件设置，但我的web.config中的smtp被忽略了，而倾向于在bin文件夹中的dll文件中设置的smtp设置。 我如何在web.config中实施邮件设置，以及为什么dll文件smtp设置优先于web.config设置。生成此代码的程序员（几年前，现在不见了）还在C＃控制器.cs文件中包含了smtp设置，我将其更新为正确的smtp设置，但这些设置也被忽略了。倾向于使用dll中的smtp设置。我是.Net网站的新手。 我还使用IIS建立了到该网站的连接，并在控制面板中设置了正确的SMTP设置，但没有任何乐趣。我收到的系统生成的电子邮件都是来自错误的邮件服务器的。 我感谢您的帮助。 谢谢
Web.config邮件设置：
<system.net>
<mailSettings>
<smtp from="mail@mysite.com">
<network host="smtp.sendgrid.net" port="587" userName="user1" password="pass1" />
</smtp>
</mailSettings>
</system.net>

答案 0 :(得分：1)
您的方法具有硬编码的值，因此当前配置不相关。
我的建议：
*如果您到处都在调用SMTP，则在程序开始时获取该值并根据需要传递它可能会很有用。

如果省略这些行，它将使用web.config中的设置
smtp.Host = "smtp.sendgrid.net";
smtp.Port = 25;
smtp.Credentials = new System.Net.NetworkCredential("user", "pass");
smtp.EnableSsl = false;
