现在有点失落了...

Little lost right now...

我正在关注以下文章，以测试/学习嵌套布局. blogs.msdn/b/marcinon/archive/2010/12/15/razor-nested-layouts-and-redefined-sections.aspx

I am following the following article to test/learn nested layouts. blogs.msdn/b/marcinon/archive/2010/12/15/razor-nested-layouts-and-redefined-sections.aspx

我收到以下错误:

The type 'System.Web.IHtmlString' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. D:\Projects\Mvc3\Tests\RazorLayouts\Layout.MvcBase\Extensions\SectionExtensions.cs 15 36 Layout.MvcBase

我有名称空间System.Web引用了...，蓝线在"RenderSection"上. 公共静态HelperResult RenderSection

I have name space System.Web referenced... and the blue line is on "RenderSection". public static HelperResult RenderSection

推荐答案

我刚刚遇到了这个问题.您可能还需要添加对" System.Web "的引用.这为我解决了.请记住，不仅是"using"语句，而且实际上是添加了对它的引用.在为控制器设置测试项目时遇到了这个问题.

I just had this issue. You may need to add a reference to "System.Web" as well. That fixed it for me. Remember, not just the "using" statement, but actually adding a reference to it. I ran into this issue while setting up a test project for my controllers.
