HtmlHelper in the controller

Question

I need an instance of HtmlHelper in my controller.

How can I create an instance? thanks

This is not built:

var h = new HtmlHelper(new ViewContext(ControllerContext, new WebFormView("omg"), new ViewDataDictionary(), new TempDataDictionary()), new ViewPage()); 

Here is a screenshot of the error

Also, when I look at the list of methods in var h , I see only my own extension methods and not the usual ones like ActionLink . So you also need to list. (solved by sternr)

Decision:

• Make sure System.Web.Mvc.Html is enabled.

• Here is the code for instantiating the HtmlHelper.

  System.IO.TextWriter writer = new System.IO.StringWriter();

  var html = new HtmlHelper(new ViewContext(ControllerContext, new WebFormView(ControllerContext, "omg"), new ViewDataDictionary(), new TempDataDictionary(), writer), new ViewPage());

Answer 1

HtmlHelper.ActionLink and most of the methods you are probably looking for are extension methods declared in the System.Web.Mvc.Html .

As for creating an instance \ using HtmlHelper inside your controller, this is bad practice as you clearly combine the interface code with the controller code. What are you trying to achieve?
