asp.net - HTTP 错误 500.19 - 更改 web.config 时出现内部服务器错误

Question

我想在我的网站上添加注册功能。当我在 Web.config 中添加配置时，我在运行项目时遇到以下错误:

HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid

详细信息:

 Detailed Error Information:
    Module     IIS Web Core
    Notification       Unknown
    Handler    Not yet determined
    Error Code     0x80070032
    Config Error       The configuration section 'authentication' cannot be read because it is missing a section declaration

我的 web.config:

<connectionStrings>      
    <add name="Model12" connectionString="data source=.\SQLEXPRESS;initial catalog=test123;integrated security=True; />
  </connectionStrings>

  <authentication mode="Forms">
 <forms loginUrl="~/FirstPage.aspx" timeout="2880" />
</authentication>

 <membership defaultProvider="CustomMembershipProvider">
     <providers>
     <clear />
     <add name="CustomMembershipProvider"
          type="MyMembershipProvider"
          connectionStringName="Model12"
          enablePasswordReset="true"
          maxInvalidPasswordAttempts="5"
          minRequiredPasswordLength="6"
          minRequiredNonalphanumericCharacters="0"
          passwordAttemptWindow="10"
          applicationName="/" />
     </providers>
</membership>

可能是什么问题？

您从 IIS 获得的消息告诉您它无法识别您在“connectionStrings”元素下的“身份验证”元素。这是因为它应该像这样保存在“system.web”元素中:

<system.web>
    <!-- Other system.web sections here-->
    <authentication mode="Forms">
        <forms loginUrl="~/FirstPage.aspx" timeout="2880"/>
    </authentication>
</system.web>
