从区域、控制器和操作中获取VirtualPath

Question

我想知道如何在给定区域、控制器和操作名称的情况下获得URL。到目前为止，我所能想到的就是：

var httpContext = new HttpContextWrapper(HttpContext.Current);
var routeData = RouteTable.Routes.GetRouteData(httpContext);

if (routeData != null) {
    var virtualPath = routeData.Route.GetVirtualPath(new RequestContext(httpContext, routeData), new RouteValueDictionary(new { area = "Pages", controller = "Home", action = "Index" }));

    if (virtualPath != null) 
        newNode.Url = "~/" + virtualPath.VirtualPath;
}

然而，它不起作用。我想知道是否有人能帮上忙。

谢谢

如果有人想知道，这是我想出的解决方案：

// Set the context
var context = new RequestContext(new HttpContextWrapper(HttpContext.Current),
    new RouteData());
var urlHelper = new UrlHelper(context);

// Set the url
var url = urlHelper.Action("Index", "Home",
    new RouteValueDictionary(new { area = "Pages" }));

我希望这对某些人有帮助。
