ASP.NET MVC：mvc pattern

There are three pieces to the MVC pattern:

The model—The domain that your software is built around. If you were buildinga blog, your models might be post and comment. In some contexts, the term modelmight refer to a view-specific model—a representation of the domain for thespecific purpose of being displayed in the user interface.
The view—The visual representation of a model, given some context. It’s usuallthe resulting markup that the framework renders to the browser, such as theHTML representing the blog post.
The controller—The coordinator that provides the link between the view and themodel. The controller is responsible for processing input, acting upon themodel, and deciding on what actionshould be performed, such as renderinga view or redirecting to another page.Continuing the blog example, the controllermight look up the most recentcomments for a post (the model) andpass them to the view for rendering.
