如果使用MVC的眼光来看,在此微观模式下,其实可以使用MVC的模式做代码的职责分离。其中所有的UI元素对象,都应该放置到View类型内,其中的事件处理都是应该放到Controller内,而数据,也就是这里的count变量和对它的操作(减一加一),应该放置到Model类内,组装Model和View则是Controller的职责。这样的思路下,代码可以改成: ...
MVC: 用户的请求首先会到达Controller,由Controller从Model获取数据,选择合适的View,把处理结果呈现到View上; MVP: 用户的请求首先会到达View,View传递请求到特定的Presenter,Presenter从Model获取数据后,再把处理结果通过接口传递到View。 MVVM: 立足于原有MVP框架并且把WPF的新特性(数据绑定DataBind、依赖属性Dependency P...
The MVC design pattern considers there to be three types of objects: model objects, view objects, and controller objects. The MVC pattern defines the roles that these types of objects play in the application and their lines of communication. When designing an application, a major step is choosi...
但问题又随之产生,在撸ASP.NET MVC时项目组一般都会在ConcreteController和Controller间加>=1层的BaseController,然后各种Logger、Authentication、Authorization和Utils均塞到BaseController里面,然后美其名为基(鸡)类(肋)。这时你会发现BaseController中的成员(方法、字段)是无机集合,要靠#region...#endregion来划分功能...
在ASP.NET的MVC模式中,有一种叫Front Controller的模式,它分为Handler和Command树两个部分,Handler处理所有公共的逻辑,接收HTTP Post或Get请求以及相关的参数并根据输入的参数选择正确的命令对象,然后将控制权传递到Command对象,由其完成后面的操作,这里面其实就是用到了Command模式。

Another problem with the MVVM design pattern that’s seldom discussed is where and when the ViewModel instances should be instantiated. This problem is also frequently overlooked in discussions of similar design patterns such as MVC. My preference is to write a ViewModel singleton that provides the...

(handled at the OS level). As such, you don’t have a need for a Controller, as clearly indicated by the “Twisting the Triad” article. Without the Controller, you’re left with the Model-View pattern for Windows applications. You have to bear this in mind as you study MVC and its...
