ASP.NET Mvc Request.Url.Host in Helper method

Question

I am trying to convert a user control to a helper method in Asp.NET MVC. However I do not seem to be able to have access to Request.Url.Host how do I get the correct host.

Answer 1

You can use

System.Web.HttpContext.Current.Request.Url.Host

Answer 2

HtmlHelper has a ViewContext property. The ViewContext property has an HttpContext property. You should be able to access the Request from there.

  public static string MyHelper( this HtmlHelper helper, ... )
  {
        var host = helper.ViewContext.HttpContext.Request.Url.Host;

        ...
  }

Update: you might also be interested in some code I wrote to mock out the HtmlHelper class for my extension tests. You can find it on my blog: http://farm-fresh-code.blogspot.com.
