Asp.net mvc .NET-从控制器上下文检索属性？

我有一个控制器

insert

操作：

<AcceptVerbs(HttpVerbs.Post)> _
Function InsertObject(<Bind(Exclude:="Id")> <ModelBinder(GetType(CustomModelBinder))> ByVal object As SomeObject) As ActionResult

End Function

如您所见，我有一个

controllerContext

和一个

ModelBindingContext

可用

如何在

BindModel

实现中获得：

部分？

我重新实现了该问题。这个问题变得过时了

Public Function BindModel( _
ByVal controllerContext As System.Web.Mvc.ControllerContext, _ 
ByVal bindingContext As System.Web.Mvc.ModelBindingContext) As Object Implements System.Web.Mvc.IModelBinder.BindModel
    For Each s In HttpContext.Current.Request.Form.Keys
        HttpContext.Current.Response.Write(s & ": " & HttpContext.Current.Request.Form(s) & "<br />")
    Next

    HttpContext.Current.Response.End()
End Function
