C# 4.0 从ASP.NET MVC 3升级到MVC 4，参数替换为route

我最近将我的项目从MVC3升级到MVC4，从那以后，我的一些操作参数被错误地传递

该行动具有以下特征：

public JsonResult FooAction(int id, int id2, string name, string name2, List<Object1> templates, Dictionary<string, string> dictionary1, Dictionary<string, List<string>> dictionary2);

然后将

字典2

设置为路线：

{key = "controller", value = "MyController"}
{key = "action", value = "MyAction"}
{key = "id", value = "123123"}

显然，我希望它只是一本空字典——有什么方法可以防止这种行为吗

[编辑]我应该提到，我使用的是默认路由行为：

routes.MapRoute(
    "Default",
    "{controller}/{action}/{id}",
    new { controller = "Home", action = "Index", id = "" } 
);

我通过在参数定义之前添加

[Bind（Prefix=“dictionary2”）]

来获得所需的行为，即

public JsonResult FooAction(int id, int id2, string name, string name2, List<Object1> templates, Dictionary<string, string> dictionary1, [Bind(Prefix = "dictionary2")] Dictionary<string, List<string>> dictionary2);

以及在应用程序启动时：

ModelBinderProviders.BinderProviders.Add(new StringDictionaryModelBinderProvider());

但我还是被打败了

public class StringDictionaryModelBinderProvider: IModelBinderProvider
{
    public IModelBinder GetBinder(Type modelType)
    {
        if (modelType == typeof (Dictionary<string, string>) || modelType == typeof (IDictionary<string, string>))
            return new StringDictionaryModelBinder();

        return null;
    }

    private class StringDictionaryModelBinder : DefaultModelBinder
    {
        public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
        {
            bindingContext.FallbackToEmptyPrefix = false;
            return base.BindModel(controllerContext, bindingContext);
        }
    }
}

ModelBinderProviders.BinderProviders.Add(new StringDictionaryModelBinderProvider());
