What are some examples of routing in ASP.NET Core?

In ASP.NET Core, routing is used to map incoming requests to specific endpoints. For example, you can define routes in the Startup.cs file using the MapGet, MapPost, etc. methods.

Can you give me a specific code example?

Sure! Here's a simple example:

app.MapGet("/hello/{name}", (string name) => {
    return $"Hello, {name}!";
});

This route responds to GET requests at /hello/{name}.

What about attribute routing?

Attribute routing allows you to define routes directly on your controller actions. For example:

[Route("api/[controller]")]
public class HelloController : ControllerBase
{
    [HttpGet("{name}")]
    public IActionResult GetHello(string name)
    {
        return Ok($"Hello, {name}!");
    }
}

How do I handle route parameters?

You can handle route parameters by defining them in the route template. For instance, in the example above, {name} is a route parameter that you can access in your action method.
