如何使用表单身份验证将用户重定向到特定页面

Question

我想配置应用程序并阻止用户直接进入应用程序中的任何页面，而无需登录，但任何用户都可以访问网站主页。

但是当我运行网页，登录页面或网站的任何页面，我得到这个错误： - The requested page cannot be accessed because the related configuration data for the page is invalid.

我无法找出我会犯错。我发布了我的web.config文件。看看它。向我展示我犯的错误以及解决方案。

的web.config

<?xml version="1.0"?>

配置的<authentication>部分应该是<system.web>部分

MSDN authentication Element

只需编辑内部下您的web.config：

<system.web> 
    <authentication mode="Forms"> 
     <forms loginUrl="/Registration/LoginPage.aspx"> 
     </forms> 
    </authentication> 
    <compilation debug="true" targetFramework="4.5.2" /> 
    <httpRuntime targetFramework="4.5.2" /> 
</system.web>
