“名称"HTML"在当前上下文中不存在"在MVC 3视图 [英] "The name 'HTML' does not exist in the current context" in MVC 3 Views

问题描述

我开始使用"MVC 3"，但遇到一些小问题.在我的视图中，当我编写如下代码时:

I´m starting to use "MVC 3" but I´m facing some little problems. In my Views, when I code something like this:

@if(Request.IsAuthenticated) {
    <text>Welcome <b>@Context.User.Identity.Name</b>!
    [ @Html.ActionLink("Log Off", "LogOff", "Account") ]</text>
}
else {
    @:[ @Html.ActionLink("Log On", "LogOn", "Account") ]
}

诸如@Request和@Html之类的对象指示错误:The name 'HTML' does not exist in the current context.

The objects like @Request and @Html is indicating an error: The name 'HTML' does not exist in the current context.

@ Context，@ ViewBag，@ Layout，@ Url和其他事件也会发生同样的情况.

The same occurs with @Context, @ViewBag, @Layout, @Url and others.

请参阅:

但是代码正确编译，没有错误.问题是我无法在视图中将Intellisense与这些对象一起使用.正常吗(我不这么认为).可能会发生什么?

But the code is correctly compiled with no errors. The problem is that I cannot use the Intellisense with theses objects in the Views. Is it normal? (I don´t think so). What could be happening?

我已经重新安装了MVC 3框架，但仍然会发生同样的情况.

I have reinstalled the MVC 3 framework but the same still occurs.

注意:这是从头开始的新项目，而不是MVC 2迁移. Razor引擎和ASPX都会发生这种情况.

Note: this is a new project from scratch, not a MVC 2 migration. This occurs both with Razor engine and ASPX.

这是Views文件夹中的Web.Config:

This is the Web.Config in the Views folder:

    <!--
        Enabling request validation in view pages would cause validation to occur
        after the input has already been processed by the controller. By default
        MVC performs request validation before a controller processes the input.
        To change this behavior apply the ValidateInputAttribute to a
        controller or action.
