In ASP.NET MVC how can I use the Razor @Url.Content() helper from C# code?

Question

I\'m trying to write a html helper extension that outputs an image tag. I need to access (within C# code) something like Razor\'s @Url.Content() helper to get the proper URL

Answer 1

Use the following to mimic Url.Content in code.

VirtualPathUtility.ToAbsolute("~/url/");

Answer 2

You can create your own instance of UrlHelper by passing in the appropriate ViewContext. For example, to do this from an image helper:

public static string CustomImage(this HtmlHelper html)
{
    var Url = new UrlHelper(html.ViewContext.RequestContext);
}

At this point you can call Url.Content() or any other UrlHelper method.

Answer 3

Yes you can.

From a controller you can call:

this.Url.Content("~/Somerelativepath?somethingelse=true");

Answer 4

You can get to the Request object and thus the URL like this:

string fullUrl = HttpContext.Current.Request.Url.AbsoluteUri;

Answer 5

Something like this perhaps?

public static string MyHelper(this HtmlHelper h)
{
      string url = h.ViewContext.HttpContext.Request.Url.AbsoluteUri;
}

Answer 6

Yes, use this code to add Url.Content into your code:

var img_btn_edit = VirtualPathUtility.ToAbsolute("~/Content/images/pencil.png");
