How to construct URLs in MVC?

Question

I am using Url.RouteUrl to create a URL to return to my user.

var path = Url.RouteUrl(new RouteValueDictionary()
            {
                { "controller", "Home"},
                {"action", "myaction"},
                {"area" , "myarea"},
            });

This returns me a nice URL with myarea/home/myaction

If I need to add an extra param to it, say like myarea/home/myaction?param1=abc, how can that be done ?

I tried

var param1Value = "abc";
var path = Url.RouteUrl(new RouteValueDictionary()
            {
                { "controller", "Home"},
                {"action", "myaction"},
                {"area" , "myarea"},
                new {param1 = param1Value },
            });

This seems like not the way to be.

Can any one suggest some way to do this ?

Try this:

    Url.Action("myAction","Home", new {area="myarea", param="paramvalue"});

Hope this helps:

return (new RedirectToRouteResult(
                    new System.Web.Routing.RouteValueDictionary(
                        new
                        {
                            controller = "Home",
                            action = "myAction",
                            area = "myArea"
                        })));

If you want to add a param to it, you may add/modify the route map in the Route Config file. Once the new key is added, the value can be specified in the above code.

Found out an elegant way of doing this.

var myDesiredUrl = FetchDomainUri();

myDesiredUrl.Path = Url.RouteUrl(new RouteValueDictionary()
{
    { "controller", "Home" },
    { "action", "myAction" },
    { "area" , "myArea" },
});

myDesiredUrl.QueryString.Add("myParam1", param1Value);
