Is there a way to send optional parameters to an action?

Can I send optional parameters (empty strings, null int?'s etc) to an action through a GET request in asp.net mvc? (one sentence question!)

You can do optional parameters with the routing table fairly easily, just specify the defaults in the route of the global.cs file.

So for a search page with an optional query and page you would have something like

RouteTable.Routes.Add(new Route
{
    Url = "Search/[query]/[page]",
    Defaults = new { controller="Search", action="Results", page=1 },
    RouteHandler = typeof(MvcRouteHandler)
});

Default page for your search is then 1.

This example is found here on Scott Gu's blog.
