Question

我刚刚安装并试图让MVCMailer工作。

我收到一条错误，指出“每个配置文件只能出现一次。有关例外，请参阅帮助主题。”

我理解基本知识，这意味着我应该只有1页标签（我猜无论如何）但看起来mvc邮件程序在我安装它时添加了几个。事实上，我不太确定它完全做了什么，但是对于像我这样的新手来说，那里有一些不熟悉的东西。

我的web.config如下所示

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

任何人都可以做出这个错误的头部或尾部，我以前没有深入研究过web.config，而且我还是犹豫不决，把它弄得一团糟！

Answer 1

您有两次Pages部分。删除其中一个并合并。它看起来像这样。

 <pages validateRequest="false" pageParserFilterType="System.Web.Mvc.ViewTypeParserFilter, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" pageBaseType="System.Web.Mvc.ViewPage, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" userControlBaseType="System.Web.Mvc.ViewUserControl, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
  <controls>
    <add assembly="System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" namespace="System.Web.Mvc" tagPrefix="mvc" />
  </controls>
   <namespaces>
        <add namespace="Mvc.Mailer" />
      </namespaces>
</pages>

Answer 2

将您的网页部分合并为一个部分：

<pages validateRequest="false" pageParserFilterType="System.Web.Mvc.ViewTypeParserFilter, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" pageBaseType="System.Web.Mvc.ViewPage, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" userControlBaseType="System.Web.Mvc.ViewUserControl, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
         <controls>
                 <add assembly="System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" namespace="System.Web.Mvc" tagPrefix="mvc" />
         </controls>
         <namespaces>
                 <add namespace="Mvc.Mailer" />
         </namespaces>
</pages>

web.config相关错误 - 每个配置文件只能出现一次
