System.Web.WebPages.Html.HtmlHelper不包含定义

时间：2016-12-07 23:05:27

标签： c# asp.net-mvc razor

我知道有很多问题都在提出同样的问题，但我已经尝试了大部分问题而且找不到我搞砸的地方。我有一个包含多个项目的解决方案。因为它们是在不同的.net版本，我最终升级到.Net 4.5，从MVC 4升级到MVC 5.我当前的问题是在视图文件中，它不会识别任何剃刀语法（请原谅我，如果这是错误的术语），如@ model，ViewBag，ActionLink，DisplayNameFor等

我确保我的软件包是最新的，webconfig文件指向正确（我认为）。例如，它是否需要指向最后的十进制版本或仅指向顶部的十进制版本 <bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="5.2.3.0" /或<bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="5.0.0.0" />，无论我是否都试过。

我也删除了bin，obj，清除了我的温度，清理并重建了。你能看到我错过的东西吗？

您的错误会告诉您问题所在。无论你的引用中的System.Web.Helpers有什么DLL版本都不匹配某个项目文件。您可以右键单击每个项目并卸载项目，然后再次右键单击不可用项目并选择“编辑项目”。查找System.Web.Helpers并确保每个项目的版本号一致，
