如何在类库项目中使用TagBuilder？

Question

I am trying to use TagBuilder in a Class Library project. I have added references to System.Web and System.Web.Mvc (v3), but in my class file the TagBuilder class is not visible.

How can I use TagBuilder in a Class Library project?

Answer 1

In Asp.Net MVC 3, it is located in:

c:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v1.0\Assemblies\System.Web.WebPages.dll

In Asp.Net MVC 4, it is located in:

c:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v2.0\Assemblies\System.Web.WebPages.dll

So make sure you have a reference to that dll.

Answer 2

您还需要对System.Web.WebPages的引用

Answer 3

对于早期版本的Asp.Net MVC，这些答案都是正确的，但是现在最好也是最简单的方法就是使用NuGet Package Manager /“管理NuGet包来解决方案......”并安装最新版本的Microsoft.Aspnet.Mvc in你的项目。

Answer 4

If you added the DLL (in System.Web.Mvc.dll), and the namespace, it should be visible to you as a class. Have you added the code above?

Answer 5

Make sure you have a using statement at the top of your file that references the System.Web.Mvc namespace. Since you have the reference added you should be good to go. Have a look at the article ' Using the TagBuilder Class to Create HTML Helpers ' for more information and an example.
