Have 2 Get() Methods In API

Question

User974100899 posted

Hi - I am sure this is super simple to an experienced asp.net coder, but I want to have 3 GET() methods. However I am getting this error

already defines a member called 'Get' with the same parameter types

This is my code - what should I change so this will compile as I wish

        public IEnumerable<appinfo> Get()
        {
            using (XamarinEntities entities = new XamarinEntities())
                return entities.appinfoes.ToList();
        }
        public IEnumerable<string> Get()
        {
            return new string[] { "id", "fname", "lname", "phone", "company", "approveduser" };
        }
        public appinfo Get(string email)
        {
            using (XamarinEntities entities = new XamarinEntities())
                return entities.appinfoes.FirstOrDefault(e => e.email == email);
        }

One way to do it is to use the ActionName attribute. This is a VB.NET example.

https://docs.microsoft.com/en-us/aspnet/web-api/overview/web-api-routing-and-actions/routing-in-aspnet-web-api

Imports System.Web.Mvc
Imports System.Web.Routing

Public Module RouteConfig
    Public Sub RegisterRoutes(ByVal routes As RouteCollection)
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}")

        routes.MapRoute(
            name:="Default",
            url:="api/{controller}/{action}/{id}",
            defaults:=New With {.controller = "Home", .action = "Index", .id = UrlParameter.Optional}
        )
    End Sub
End Module

Imports System.Web.Http
Imports DAL
Imports Entities

Namespace Controllers

    <CustomExceptionFilter>
    Public Class TaskController
        Inherits ApiController

        Private ReadOnly _daotask As IDaoTask

        public sub New (daotask As IDaoTask)
            _daotask = daotask
        End sub

        <HttpGet>
        <ActionName("GetTaskById")>
        public Function  GetTaskById(ByVal id As int32) as DtoTask
            return _daotask.GetTaskById(id)
        End Function
        
        <HttpGet>
        <ActionName("GetTasksByProjectId")>
        public  Function GetTasksByProjectId(byval id as int32) as List(Of DtoTask)
            return _daotask.GetTasksByProjectId(id)
        End Function

        <HttpPost>

        public sub  CreateTask(ByVal dto As DtoTask)
            Call _daotask.CreateTask(dto)
