Asp net mvc routing always to root with parameters


ASP.NET is a popular programming used for building web applications. One common faced by developers is how to handle routing in ASP.NET MVC applications. In this article, we will explore a solution to the problem of always routing to the root with .

The Problem

By default, ASP.NET MVC routing maps URLs to actions on a predefined set of . However, in some cases, you may want to route all requests to the root of your , still passing parameters to the controller action.

The Solution

To this problem, we can make use of the ASP.NET MVC routing system and define a custom route that handles the desired behavior. Let's take a look at an example:

// Define a custom route in the RouteConfig.cs file
    name: "RootWithParameters",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }

In the above code snippet, we define a custom route named “RootWithParameters” that matches the URL pattern “{controller}/{action}/{id}”. This means that any request to the root of the application will be mapped to the “Index” action of the “Home” controller, with an optional “id” parameter.

Now, let's see how we can use this custom route in our controller:

public class HomeController : Controller
    public ActionResult Index(string id)
        // Handle the request with the provided id parameter
        return View();

In the above code snippet, we have a simple HomeController with an Index action that takes an optional “id” parameter. This action will be invoked when a request is made to the root of the application, with or without the “id” parameter.


In this article, we have explored a solution to the problem of always routing to the root with parameters in ASP.NET MVC. By defining a custom route and handling the desired behavior in the controller, we can achieve the desired routing behavior. This approach provides flexibility and control over how URLs are mapped to controller actions in your ASP.NET MVC application.
