What are route parameters in ASP.NET?
Route parameters are placeholders in the URL that allow you to capture values from the URL and use them in your application.
Can you give me an example of how to use route parameters?
Sure! In ASP.NET, you might define a route like this: routes.MapRoute("Default", "Home/{id}");
Here, {id}
is a route parameter.
How do I access the value of a route parameter in my controller?
You can access route parameters in your controller action by adding them as parameters. For example: public IActionResult Home(int id)
.
What happens if a route parameter is not provided?
If a route parameter is not provided, the routing system will not match the route, and you may get a 404 error unless you have a default value.
