Method 1

Url.Action("Action", "Controller", null, Request.Url.Scheme);

How to include the following in the Form Action attribute?

1. Protocol(http:// or https://)
2. HostName

3. QueryString

4. Port

@{
    var actionURL = Url.Action("Action", "Controller", 
                               FormMethod.Post, Request.Url.Scheme)  
                    + Request.Url.PathAndQuery;
}
@using (Html.BeginForm("Action", "Controller", FormMethod.Post, 
                                                   new { @action = actionURL }))
{
}

Method 2

besides the default route:

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Application", action = "Index", id = UrlParameter.Optional }
        );

you may need to implement a new one :

        routes.MapRoute(
            name: "ControllerXActionYRoute",
            url: "controllerX/actionY",
            defaults: new { controller = "controllerX", action = "actionY" }
        );

and then you can use :

<div>@Url.Action("Action", "Controller", null, Request.Url.Scheme);</div>

*EDIT: *

to get the full url you must go to absolute.

<div>VirtualPathUtility.ToAbsolute(@Url.Action("Action", "Controller"));</div>
