我在使用 Razor2 视图时遇到了一个非常奇怪的问题。下面的代码是智能感知抛出红色波浪的实际代码，只是名称已更改。
@model Space.ViewModels.PropertyAdminViewModel
@{
ViewBag.Title = "Create";
ViewBag.UmbracoTitle = "Create Property";
Layout = "../Shared/_Layout.cshtml";
InitView();
AnalysePreviousState();
SortErrorsPerStep();
GetStepToDisplay();
}
<script src="../../Scripts/jquery-1.8.2.min.js"></script>
<script src="../../Scripts/jquery.validate.min.js"></script>
<script src="../../Scripts/jquery.validate.unobtrusive.min.js"></script>
<script src="../../Scripts/AdminScripts.js"></script>
@Html.ValidationSummary(ErrorMessage)
@using (Html.BeginForm())
{
@Html.Hidden("CurrentStep", StepToDisplay.ToString(), new { id="CurrentStep"})
<input id="AddressButton" type="submit" name="@Button.AddressButton.ToString()" value="Address Details" />
<input id="DetailsButton" type="submit" name="@Button.DetailsButton.ToString()" value="Details & Description" />
<input id="MediaButton" type="submit" name="@Button.MediaButton.ToString()" value="Images & Documents" />
switch (StepToDisplay)
{
case Step.Address:
Html.RenderPartial("_AddressDetailsForm", ViewData.Model.Address);
break;
case Step.Details:
Html.RenderPartial("_PropertyDetailsForm", ViewData.Model);
break;
case Step.Media:
Html.RenderPartial("_MediaUploadEditForm", ViewData.Model.MediaItems);
break;
}
<input id="BackButton" type="submit" name="@Button.BackButton.ToString()" value="Back" />
<input id="NextButton" type="submit" name="@Button.NextButton.ToString()" value="Next" />
<input id="FinishButton" type="submit" name="@Button.FinishButton.ToString()" value="Finish" />
} <-- `SQUIGGLY`

当我将鼠标悬停在 Viewbag 上时，我会看到通常的智能感知弹出窗口，而将鼠标悬停在 Title 上会解释正常的“在运行时评估”。
有没有人遇到过这个问题？我查看了其他问题，但它们都有代码拼写错误或真正的错误。我知道这不是程序集参考问题，否则 Intellisense 不会知道 Viewbag 是什么。
更新
看起来 Intellisense 遇到了特别是动态分配的问题。正常的服务器代码不会遇到上述问题，而像 Viewbag 分配或在 @{//code here} 中指定布局之类的东西似乎已损坏。另请注意，这只发生在我的 .cshtml 文件之一上，其他文件不受影响。
更新 2 这是测试视图的结果。源文件是 ASP.NET 临时文件中生成的代码文件。
Compiler Error Message: CS1513: } expected
Source Error:
Line 259: #line default
Line 260: #line hidden
Line 261:WriteLiteral("\r\n");
Line 262:
这是与编译的临时文件中的上述错误相关的代码：
WriteLiteral(" value=\"Finish\"");
WriteLiteral(" /> \r\n");
#line 46 "F:....Create.cshtml"
} <-- see the brace!? It's right there so why does the compiler freak out?
#line default
#line hidden
WriteLiteral("\r\n");
