How to pass multiple parameters to a get method in ASP.NET Core

Question

How can I pass in multiple parameters to Get methods in an MVC 6 controller. For example I want to be able to have something like the following.

[Route(\"api         


        

Answer 1

Why not using just one controller action?

public string Get(int? id, string firstName, string lastName, string address)
{
   if (id.HasValue)
      GetById(id);
   else if (string.IsNullOrEmpty(address))
      GetByName(firstName, lastName);
   else
      GetByNameAddress(firstName, lastName, address);
}

Another option is to use attribute routing, but then you'd need to have a different URL format:

//api/person/byId?id=1
[HttpGet("byId")] 
public string Get(int id)
{
}

//api/person/byName?firstName=a&lastName=b
[HttpGet("byName")]
public string Get(string firstName, string lastName, string address)
{
}
