剃刀看不到我的右大括号

Question

我遇到了Razor2视图的一个非常奇怪的问题。下面的代码是实际代码，其中智能感知正在抛弃红色曲线，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 &amp; Description" /> 
    <input id="MediaButton" type="submit" name="@Button.MediaButton.ToString()" value="Images &amp; 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我得到的通常的智能感知弹出，并徘徊标题解释了正常“在运行时进行评估”。

有没有人遇到过这个问题？我查看了其他问题，但他们都有代码拼写错误或真正的错误。我知道这不是一个组装参考问题，否则Intellisense不会知道Viewbag是什么。

UPDATE

它看起来像智能感知是否有问题特别动态分配。普通服务器代码不会遇到上述问题，而像Viewbag分配或指定@ {//此处代码}中的布局似乎已破坏。另请注意，这只发生在我的一个.cshtml文件中，而其他文件不受影响。

UPDATE 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: 

这是与上述错误在编译的临时文件中的代码：

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");    

Answer 1

我不知道，你可以不写正常的C＃代码到剃刀意见。

Answer 2

你需要这样的：

@switch (StepToDisplay) 

它看到闸刀开关括号截至收盘到你之前的那个。您甚至可能需要将开关放在一个剃须刀代码块中@{ switch(){} }

另外，如果您使用的是ReSharper，它会突出显示它的实际代码块，并且您会看到Razor在想什么该块的结束将是。

编辑：

它应该是这样的：

@using (Html.BeginForm()) 
{ 
    // remove the @ from before the Html on this line 
    Html.Hidden("CurrentStep", StepToDisplay.ToString(), new { id="CurrentStep"}) 
    // This html causes razor to switch back to "html mode" 
    <input id="AddressButton" type="submit" name="@Button.Step1Button.ToString()"... 

    ... 

    // Add an @ here, because razor is now in Html mode 
    @switch (StepToDisplay) 
    { 
     ... 
    } 

    // Back in html mode again, so we need @'s 
    <input id="BackButton" type="submit" name="@Button.BackButton.ToString()"... 
    ... 
}
