Question

所以我是MVC4和C＃的新手，我现在已经设计了这个网站大约2周了，而且知识产权没有任何问题。

2天后，Visual Studio告诉我@Viewbag和其他@命令不属于我的项目，我可能会遗漏某些内容，或者它告诉我Viewbag在当前上下文中不存在。

我不确定如何解决这个问题（我已经重新启动了项目并且我正在处理的机器）仍然显示下划线并告诉我它在上下文中不存在

因为当我查看/尝试新代码时我仍然是新手，因此所有错误都是非常困难的。

System.Web.WebPages.Html.htmlHelper'不包含'Actionlink'的定义....缺少程序集引用？

我在Razor视图中的任何@codes都会出现此错误，以及C＃@的

Answer 1

确保您已在web.config的appSettings中指定了正在使用的Razor版本：

<appSettings>
    <add key="webpages:Version" value="2.0.0.0" />
    <add key="ClientValidationEnabled" value="true" />
    <add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>

还要确保您的观看次数位于标准位置（例如，~/Views文件夹）。

Answer 2

创建一个新的Internet Web应用程序取出您的更改（从旧代码中）插入新创建的Internet Web App配置文件，添加旧的更改（逐行跳过所有读取，看看是否有任何真正搞乱了）

希望有所帮助

Answer 3

在我错误地将<appSettings>添加到Views Web.config而不是“main”Web.config文件中之后出现了同样的问题。花了我几个小时来弄清楚......
