ASP.Net MVC Custom Model Binding explanation
提问by Richbits
Is anyone aware of where I can find a tutorial for building a custom model binder.
有谁知道我在哪里可以找到构建自定义模型绑定器的教程。
I have found several issues using the default model binder with EntitySets (not populating when creating new objects and creating duplicates on editing objects) and find that my UI doesn't match my model exactly (e.g. time fields formated "hh:mm am" do not match with a timespan). I therefore want to look at whether creating a custom model binder is a better solution. I have found a couple of examples: hereand here. The first is I believe out of date and the second doesn't really explain what is going on.
我发现使用带有 EntitySets 的默认模型绑定器存在几个问题（在创建新对象时不填充并在编辑对象上创建重复项），并发现我的 UI 与我的模型不完全匹配（例如格式为“hh:mm am”的时间字段）与时间跨度不匹配）。因此，我想看看创建自定义模型绑定器是否是更好的解决方案。我找到了几个例子：here和here。第一个是我认为已经过时，第二个并没有真正解释发生了什么。
My main problem is that I don't fully understand what the ControllerContext and ModelBindingContext Of the BindModel method actually are, i.e. how they relate to the controller and model.
我的主要问题是我不完全理解 BindModel 方法的 ControllerContext 和 ModelBindingContext 实际上是什么，即它们与控制器和模型的关系。
I would be grateful if someone point me to a tutorial or could take a look at the dave hayden's post and show me how it might look with the current implementation of MVC.
如果有人给我指点教程或者可以看看dave hayden的帖子并向我展示它与当前 MVC 实现的外观，我将不胜感激。
