How can I customize routing in ASP.NET MVC?

You can customize routing in ASP.NET MVC by modifying the RouteConfig.cs file in the App_Start folder. You can define custom routes using the MapRoute method.

Can you give me an example of a custom route?

Sure! For example, you can create a route like this: routes.MapRoute(name: "Product", url: "Products/{id}", defaults: new { controller = "Product", action = "Details" }); This maps URLs like /Products/5 to the Details action of the Product controller.

What if I want to add constraints to my routes?

You can add constraints by using the constraints parameter in the MapRoute method. For example: routes.MapRoute(name: "Product", url: "Products/{id}", defaults: new { controller = "Product", action = "Details" }, constraints: new { id = "\d+" }); This ensures that the id must be a number.

How do I handle 404 errors for custom routes?
