MVC5对象引用未设置为Scripts.Render上的对象实例

Question

我正在使用Asp.net MVC5,并且自从使用Microsoft MVC平台4年以来没有遇到过这样的模糊错误!默认MVC5模板中的管理页面中发生错误.这里是第26行的_layout.cshtml文件:

Line 24:     <![endif]-->
Line 25: 
Line 26:     @Scripts.Render("~/js/intf")
Line 27:     <script>
Line 28:         if (document.documentMode === 10) {

Stack Trace说:

编辑:你想要捆绑代码,我把其中一个放在这里:

bundles.Add(new ScriptBundle("~/js/intf").Include(//first internal scripts
                "~/js/jquery*",
                "~/js/modernizr.js",
                "~/js/ie-prototype-polyfill.js",
                "~/js/prettyPhoto.js"));

注意:如果我纪念错误行(样式/脚本捆绑行)错误将@ViewBag.Title作为新错误!我认为Razor视图引擎在这里遇到了麻烦,因为它无法实例化视图的代码要求,但为什么呢？

我知道使用Microsoft技术时的一些错误与它所说的错误并不真正相关.请给我留下你的有益经验.谢谢.

更新:~/views/Account/Manage.cshtml文件的简洁内容可能很有用:

@using Social.Models;
@using Microsoft.AspNet.Identity;

@{
    ViewBag.Title = "manage";
}

<div class="layout-app">

    <div class="row row-app margin-none">

        <div class="col-md-12">

            @if (ViewBag.HasLocalPassword)
            {
                 @Html.Partial("_ChangePasswordPartial")
            }
            else
            {
                 @Html.Partial("_SetPasswordPartial")
            }
        </div>
    </div>
</div>

Answer 1

我ViewBag在主布局文件中滥用以在其他页面中使用。我的结构ViewBag作为必填字段，所以我必须在之前实例化它。但是我忘记实例化它导致触发这样的错误并且它似乎与Scripts.Render.
