ASP. net MVC 3 has been officially released. Now it is estimated that many people are studying hard, and I am not an exception. I just saw an article and introduced three very useful methods: renderbody, now let's summarize the renderpage and rendersection. 1. renderbody Without the "Master page" in the razor engine, the "layout" Page (_ layout. cshtml) is placed in the shared view folder. On this page, the @ Renderbody () In fact, its role is simila
