Changing Model Binder per Controller instead of by type or with attributes?
原标题:

I d like to be able to swap model binders out on a per Controller or per ActionMethod basis.

AFAIK the only options supported by the framework are to bind a model binder to a specific type.

How could I change my model binder per Controller or per ActionMethod in a clean way?

You can use ModelBinderAttribute. Example

[HttpPost]
public ActionResult CreateTask([ModelBinder(typeof(TaskBinder))] Task task)

I would suggset you to implement a Composite model binder like here

It s a kind a chain of responsabilities and the model binder that can handle the bind will be applied.
