asp.net 4.5启用表单身份验证错误

在我的ASP.NET（4.5）Forms应用程序中，我试图启用身份验证和授权，但无法使其正常工作。我发现了将以下内容添加到Web.config文件的说明，但是对任何页面的所有请求都会得到错误 HTTP错误500.19 - 内部服务器错误由于页面的相关配置数据无效，所请求的页面无法访问。asp.net 4.5启用表单身份验证错误

而且，在我的Web.config文件中存在错误信息“元素“的System.Web具有无效子元素‘形式’。

由于Visual Studio创建的认证码开箱，我？认为这将是什么，应该很容易让我怎样才能解决这个

我发现这个信息网上添加到我的web.config中启用身份验证和授权：

<system.web> 
    <authentication mode="Forms"> 
    <forms loginUrl="~/Account/Login" timeout="30" /> 
    </authentication> 
</system.web> 

<system.webServer> 
    <security> 
    <authentication> 
     <anonymousAuthentication enabled="true" /> 
    </authentication> 
    </security> 
<system.webServer>

这里是我的没有连接字符串ele的Web.config ments：

，你将只有1个配置文件在你的根文件夹？看看这里https://stackoverflow.com/questions/1866229/forms-authentication-web-config-set-up – MethodMan

为什么你的loginUrl没有扩展名？不应该像这样读取：？ – Ian

web.config是错误的。你有这样的：

<authentication mode="Forms" /> 
<forms loginUrl="~/Account/Login" timeout="30" />

它应该是：

<authentication mode="Forms" > 
    <forms loginUrl="~/Account/Login" timeout="30" /> 
</authentication>

谢谢 - 我做了更正，但现在出现此错误：HTTP错误500.19 - 内部服务器错误请求的页面无法访问，因为页面的相关配置数据无效。这指向：配置源： 78： 79： 80： – ikask
