.NET Core: Route to a Subfolder and Add Multiple Actions in a .NET Web API Project

Change the default WeatherForecastController.cs to use a subfolder and add multiple actions. I created the subfolder "v1." While this is not technically needed (you can map the default controller), it helps to have your folder structure mirror the route prefix.

copy

//Folder
///Controllers/v1/WeatherForecastController.cs


using Microsoft.AspNetCore.Mvc;

namespace MyWebsite.Controllers.v1
{
    [ApiController]
    //adding "v1/" to add a v1 prefix
    //adding /[action] to use the function names as endpoints
    [Route("v1/[controller]/[action]")]
    public class WeatherForecastController : ControllerBase
    {
        private static readonly string[] Summaries = new[]
        {
			"Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
		};

        private readonly ILogger<WeatherForecastController> _logger;

        public WeatherForecastController(ILogger<WeatherForecastController> logger)
        {
            _logger = logger;
        }
		

        //remove this, code changed to return only 1
        //[HttpGet(Name = "GetWeatherForecast")]
        //url: /v1/WeatherForecast/Get
        public WeatherForecast Get()
        {
            return Enumerable.Range(1, 5).Select(index => new WeatherForecast
            {
                Date = DateTime.Now.AddDays(index),
                TemperatureC = Random.Shared.Next(-20, 55),
                Summary = Summaries[Random.Shared.Next(Summaries.Length)]
            })
            .ToArray()[0];
        }


        //url: /v1/WeatherForecast/List
        public IEnumerable<WeatherForecast> List()
        {
            return Enumerable.Range(1, 5).Select(index => new WeatherForecast
            {
                Date = DateTime.Now.AddDays(index),
                TemperatureC = Random.Shared.Next(-20, 55),
                Summary = Summaries[Random.Shared.Next(Summaries.Length)]
            })
            .ToArray();
        }
    }
}
