Question

I am using MVC 3 application and used web api controller.

I want to call a method with parameters .

But when I try to call the method I get Internal Server error(500)
My global.asax is:

routes.MapHttpRoute(
  name: "PostMethod2",
  routeTemplate: "api/mycontroller/{a}/{b}",
);

Should I add any code to application_start of Global.asax to route to the parameterized method?

Your route configuration doesn’t seem legit, a proper one would look like below

routes.MapHttpRoute(
  name: "PostMethod2",
  routeTemplate: "api/{controller}/{action}/{a}",
);

Note, “{controller}” and “{action}” can’t be random. MVC uses it to map to your controller and action(method) respectively. {a} will be mapped to your parameter “int a”. MVC uses mapping by convention.
