Direct route to custom search with MVC

问题

I need to create a custom route with MVC to build a custom search:

Default Home's Index's Action:

    public virtual ActionResult Index()
    {
        return View();
    }

And I would like to read a string like this:

    public virtual ActionResult Index(string name)
    {

        // call a service with the string name

        return View();
    }

For an URL like:

www.company.com/name

The problem is that I have this two routes but it's not working:

        routes.MapRoute(
            name: "Name",
            url: "{name}",
            defaults: new { controller = "Home", action = "Index", name = UrlParameter.Optional }
        );

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

This way, any controller other then Home is redirected to Home, and if I switch the order, it can't find the Index Home Action.

You can use attribute routing for this. You can see the details about the package here. After installing the attribute routing package. Now a days it is installed by default for MVC5 application. Change your action method as below:

[GET("{name}")]
public virtual ActionResult Index(string name)
{

    // call a service with the string name

    return View();
}

Here's a catch for the code above: The router will send the requests without the name also to this action method. To avoid that, you can change it as below:

[GET("{name}")]
public virtual ActionResult Index2(string name)
{

    // call a service with the string name

    return View("Index");
}
