Question

Today I found it hard to discover the difference between two MVC action methods.

My arearegistration:

  public override void RegisterArea(AreaRegistrationContext context)
  {
     // My test route.
     context.MapRoute(
         "testRoute",
         "Test/{action}",
         new { controller = "Test", action = "Index" }
     );
  }

And the two methods, that differ from both the used http-method and the parameter.

  [HttpPost]
  public ActionResult Test(TestModel model)
  {
     return View("Confirm", model);
  }

  [HttpGet]
  public ActionResult Test(string title)
  {
     Response.Write(title);
     Response.End();

     return null;
  }

Unregarded the http method, it will always end up rendering the second Test() method. Even when no title parameter is supplied (normally by querystring /Test/Test/?title=test). Probably because string is a reference type and can be null.

But how to overcome this problem? How to make a difference between these methods?

Thanks in advance.

Answer 1

I follow this signature, basically always use the ‘GET’ method signature with the model as last parameter.

[HttpPost]
public ActionResult Test(string title, TestModel model)

By the way, I’ve never seen the behavior you’ve mentioned. So I doubt whether this is a MVC problem rather than something in your configuration. [HttpGet] methods never fire on a POST method. Is the method really post (check the Request property of your ControllerContext).
