Using a custom model binder for an argument of a controller action
I have a controller action that looks like:
public ActionResult DoSomethingCool(int[] someIdNumbers)
{
...
}
I would like to be able to use a custom model binder the create that array of IDs from a list of checkboxes on the client. 开发者_高级运维 Is there a way to bind to just that argument? Additionally, is there a way for a model binder to discover the name of the argument being used? For example, in my model binder I would love to know that the name of the argument was "someIdNumbers".
The ModelBinder
attribute can be applied to individual parameters of an action method:
public ActionResult Contact([ModelBinder(typeof(ContactBinder))]Contact contact)
Here, the contact
parameter is bound using the ContactBinder
.
To discover the name of the argument you can use the ModelBindingContext.ModelName property
public class MyModelBinder : IModelBinder
{
public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
var thisIsTheArgumentName = bindingContext.ModelName;
}
}
