ASP.NET MVC：主场迎战的ModelState ModelStateDictionary [英] ASP.NET MVC: ModelState vs. ModelStateDictionary

问题描述

我有其中有一个被触发时一定控制方法的调用方法的服务。

I have a service which has a method that's called when a certain controller method is triggered.

我的服务会返回一个自定义的结果对象的 PlacementResult 的中，我想回去传达可能发生错误（验证）到控制器的方法。

My service returns a custom result object PlacementResult in which I want to communicate errors that may have happened (validation) back to the controller method.

应该 PlacementResult 的具有的ModelState或ModelStateDictionary通信错误返回给控制器（和最后查看）？如何将我这串起来？

Should PlacementResult have a ModelState or a ModelStateDictionary to communicate errors back to the controller (and finally view)? How would I string this together?

最后，我怎么得到的ModelState / ModelStateDictionary（无论你告诉我，我应该选择）回视图（突出显示相应的文本框中，显示错误消息等等）？

Finally, how do I get the ModelState/ModelStateDictionary (whichever you tell me I should choose) back into the view (highlighting the appropriate text box, show the error message etc.)?

感谢您！
