Question

I am trying to use this UrlHelper extension method:

public static string ToPublicUrl(this UrlHelper urlHelper, Uri relativeUri)
{
    var httpContext = urlHelper.RequestContext.HttpContext;

    var uriBuilder = new UriBuilder
    {
           Host = httpContext.Request.Url.Host,
           Path = "/",
           Port = 80,
           Scheme = "http",
    };

    if (httpContext.Request.IsLocal)
    {
        uriBuilder.Port = httpContext.Request.Url.Port;
    }

    return new Uri(uriBuilder.Uri, relativeUri).AbsoluteUri;
}

This methd takes a relative Uri as a parameter. I am trying to call this method within a controller action and I cannot figure out how to get a relative Uri for the current Action

Can someone point me in the right direction?

Answer 1

You can get the relative path based on a specific action name using:

urlHelper.Action("someActionName" /*, "someControllerName" */);

And you can get the someActionName, and someControllerName values for the current action using:

ViewContext.Controller.ValueProvider["action"].RawValue
ViewContext.Controller.ValueProvider["controller"].RawValue
