MVC Web Api calling method not working properly - asp.net-mvc

Question

I am trying to implement three methods controller
public IEnumerable<string> Get()
{
return new string[] { "value1", "value2" };
}
public IEnumerable<string> Get(int id)
{
return new string[] { "sa1", "sa2" };
}
[HttpGet]
public IEnumerable<string> password()
{
return new string[] { "password", "password" };
}
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
But When i try to call http://localhost:49365/api/mycontrollername/password
it's always showing The request is invalid.

Answer 1

if you want to call an api function like "http://localhost:49365/api/mycontrollername/password"
you have to add ActionName attribute on the controller and add route on the Routeconfig.cs;
here is the example
[ActionName("GetEmployees")]
public IEnumerable<Employee> GETEmployees()
{
return _db.Employees.AsNoTracking();
}
routes.MapRoute(
name: "Default",
url: "api/{controller}/{action}/{id}",
defaults: new { controller = "Employees", action = "GetEmployees", id = UrlParameter.Optional }
);

I suspect it is attempting to call Get(int id) and then trying to pass the word "password" as the integer parameter. From what I can recall it's down to convention-over-configuration in that when you make a GET request it looks for a method named Get. In this case it finds one. Then based on the routing, i.e. after the controller name comes an ID, it looks at the next part of the URL, in this case "password", and then uses that as a value for the id argument.
If you were to remove the two Get methods you probably find that your URL works, but if you add other HttpGet methods you will run into other issues related to "multiple actions found". The following discussion may help if you decide you need to have multiple HttpGet methods:
