ASP.net and CustomModelBinder and a prefix

Question

With the default ModelBinder and its attribute Bind we can set a prefix like this:

public ActionResult Save([Bind(Prefix="test")] Person p)) {

}

I have a CustomModelBinderAttribute which returns a bespoke ModelBinder:

public ActionResult Save([PersonBinderAttribute(Prefix="test2")] Person p)) {

}

How do I access the value of Prefix from within my bespoke model binder?

Answer 1

I don't believe you can. I'd declare the prefix as a constant at the top of the Controller and just use that.

private const string c_prefix = "test2";
public ActionResult Save([PersonBinderAttribute(Prefix=c_prefix)] Person p)) {
    var prefix = c_prefix;
}

It is my understanding that anything you declare in the Attribute can only be used by the Attribute.
