不久，一位官员来访，他说：“你已经去世了，3年前。”。B) It is suggested to start from a simple scene and discover or design a certain pattern by yourself. From this, you can understand how the model solves the problem. In this way, the model becomes your own thing, and you will not have the problem that it is easier said than done. All design patterns are just the application of basic principles and concepts in specific occasions. You may not know the name of a design pattern, but you know all its advantages, disadvantages, variants and applications. Seeing mountains is not mountains, seeing water is not water.Let's give you a few more macros for your reference, and compare them with the above "Specific Symbol Representation Method of Macro Definition".而且此女和大王之间，苏岸不禁暗自猜测着，想来尹旭也会乐见其成的。Application scenario: Mediator mode is generally applied to situations where a group of objects communicate in a well-defined but complex way, and situations where you want to customize a behavior distributed in multiple classes but do not want to generate too many subclasses.PS: Many forums have seen beginners ask whether WCF still needs to learn in depth, because they think these technologies may be outdated. Maybe Microsoft will launch a new SOA implementation scheme at that time. Wouldn't it be a waste of time to learn in depth, so they feel that there is no need to learn in depth and just know how to use them. I had the same feeling about this problem before, but now I think that although WCF technology may be replaced, the key to understanding a technology in depth is not to know some more advanced API calls, but to understand its implementation mechanism and way of thinking. Even if the latter technology is replaced, the mechanism behind it is definitely similar. Therefore, if you have a thorough understanding of a technology, you will feel familiar with the new technology and relaxed about it. In addition, after you have a thorough understanding of a technology, you dare to say that you have mastered the technology well during the interview, instead of saying that you use it a lot at ordinary times. Once you ask deeply, you do not know the implementation principle behind it. This is also why I want to write WCF series. I hope this opinion is helpful to some beginners.********下章晚八点。
