Continue the previous article ASP. NET development, from the second layer to the third layer, to the object-oriented http://www.cnblogs.com/insus/p/3822624.html. We learned how to change our program from Layer 2 to Layer 3. In this article, we will learn about Object-Oriente

Preface: It has been three months since the publication of the [Layer 2] in the blog series of "men are down to Layer 3, according to the previous visits and comments, many of my friends still like practical blog posts. After all, we are all called "siege lions", so we should check whether the "siege lions" are qualified and whether we can "build a house" instead

Layer-3 switches are quite common, so I have studied the basic principles and design ideas of the layer-3 switches. I will share them with you here, hoping they will be useful to you. Based on the introduction of the three-layer switch technology and the working principle of

Recently I saw an article about anti-L3ArticleWhen my hands itch, I will sacrifice some time to discuss this old topic. 1. What is Layer 3? Many people love to confuse the three-layer architecture with MVC, but we can consider their differences from the simplest perspective: In the design pattern, there is usually such a chapter, the MVC design pattern,
