这是我的web.config邮件设置:

<system.net>
    <mailSettings>
      <smtp deliveryMethod="Network" from="smthg@smthg.net">
        <network defaultCredentials="true" host="localhost" port="587" userName="smthg@smthg.net" password="123456"/>
      </smtp>
    </mailSettings>
  </system.net>

这是我如何尝试从中读取值 web.config

 var smtp = new System.Net.Mail.SmtpClient();
 var credential = new System.Net.Configuration.SmtpSection().Network;

 string strHost = smtp.Host;
 int port = smtp.Port;
 string strUserName = credential.UserName;
 string strFromPass = credential.Password;

但凭据始终为空.我如何访问这些值？

我想在actionLink中使用"data-toggle".像这样;

 Html.ActionLink("Delete", "Users", "Admin", new { item.UserId , strRole = strRole }, new { id = "cmdDelete", href="#myAlert",  data-toggle="modal" })

不幸的是,不接受.我如何像标准链接一样使用"数据切换"？

我有两个表,第一个(table1)有28500行,另一个(table2)有17450行.我想比较这些表,发现table1行中不存在.

SELECT * FROM table1 WHERE ID NOT IN (SELECT DISTINCT(ID) FROM table2)

有什么建议吗？

如何在我的web项目中使用mvc4使用两个不同的母版页或布局？
