在我的 ASP.NET MVC 5 项目的 _Layout.cshtml 文件中获取 System.NullReferenceException [副本]-解网

问：

什么是 NullReferenceException，如何修复它？（26 个答案）

2年前关闭。

我开始在项目的 _Layout.cshtml 文件中收到 System.NullReferenceException。它发生在第 16 行 - @Scripts.Render（“~/bundles/modernizr”）。我删除了捆绑包，错误只是击中了一个阵容。所以我删除了所有捆绑包，但它仍然移动到上面的标题行。

以下是错误详细信息：

System.NullReferenceException
  HResult=0x80004003
  Message=Object reference not set to an instance of an object.
  Source=App_Web_erjqyhfy
  StackTrace:
   at ASP._Page_Views_Shared__Layout_cshtml.Execute() in C:\My_Code\CompetitionTracker\CompetitionTracker\Views\Shared\_Layout.cshtml:line 16

   at System.Web.Mvc.ControllerActionInvoker.InvokeActionResultFilterRecursive(IList`1 filters, Int32 filterIndex, ResultExecutingContext preContext, ControllerContext controllerContext, ActionResult actionResult)

这是我_Layout头：

<head runat="server">
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <title>@ViewBag.Title | @ConfigurationManager.AppSettings["appName"]</title>

    @Styles.Render("~/Content/css")

    @Scripts.Render("~/bundles/jquery")
    @Scripts.Render("~/bundles/modernizr")
    <script src="~/Scripts/Site.js"></script>
    <script src="https://www.google.com/recaptcha/api.js" async defer></script>
    <script src="https://kit.fontawesome.com/92e259da1e.js" crossorigin="anonymous"></script>
</head>

当我删除导致异常的项目时，我最终会得到这个打开的选项卡......

我不知所措！请帮忙！是什么原因导致了这种情况！？我真的不认为这与抛出错误的实际行有任何关系！
