ASP.NET Web API 2 Same Route Name Different POST Model Type

Question

I'm trying to have two action methods on an API controller with the same [Route] name, but different parameter types. One which takes a particular object, and the other which takes an array of that object type.

The model binder doesn't seem to be able to distinguish between these and I get the following error returned:

Multiple actions were found that match the request

Is there any way of having two POST methods with the same route but different parameter types?

Answer 1

You can't have 2 actions with same routing and same http verb (like Post). And I think that it's beter to use different routings for this example:

/api/controllerName/PostType

/api/controllerName/PostListType

it will be more readible and esier to mantain in future. And when someone else will create client app routing will be self explanatory.
