Question

I would like to know the best way to globally handle “The parameters dictionary contains a null entry for parameter x” error.

I realize that I can always set parameters as nullable type and test them using their HasValue property.

I’d rather find a more generic approach.

Any ideas?

It’s not exactly a global approach, but if your actions’ parameters have sensible defaults, why not try just making them optional parameters? For example :

public ActionResult Index(int id = 0, string name = "user") { ... }
