asp.net 4.5啓用表單身份驗證錯誤

在我的ASP.NET（4.5）Forms應用程序中，我試圖啓用身份驗證和授權，但無法使其正常工作。我發現了將以下內容添加到Web.config文件的說明，但是對任何頁面的所有請求都會得到錯誤 HTTP錯誤500.19 - 內部服務器錯誤由於頁面的相關配置數據無效，所請求的頁面無法訪問。asp.net 4.5啓用表單身份驗證錯誤

而且，在我的Web.config文件中存在錯誤信息「元素「的System.Web具有無效子元素‘形式’。

由於Visual Studio創建的認證碼開箱，我？認爲這將是什麼，應該很容易讓我怎樣才能解決這個

我發現這個信息網上添加到我的web.config中啓用身份驗證和授權：

<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>

這裏是我的沒有連接字符串ele的Web.config ments：

，你將只有1個配置文件在你的根文件夾？看看這裏https://stackoverflow.com/questions/1866229/forms-authentication-web-config-set-up – MethodMan

爲什麼你的loginUrl沒有擴展名？不應該像這樣讀取：？ – Ian

web.config是錯誤的。你有這樣的：

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

它應該是：

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