Soon I saw Li Jianzhong's C # Object-Oriented Design Pattern Lecture on MSDN's Webcast. A very good series of lectures gave me a new understanding of design patterns. I realized that learning design patterns, specifically learning object-oriented design patterns, should start with learning object-oriented. "The principle of object-oriented is like understanding the rules of chess, and the design pattern is equivalent to a mess. I don't know what the rules look at." Since I have been doing ASP.NET development for the previous year, although I have been writing classes, learning Duwamish to make hierarchical architecture, typed DataSet and custom entity classes, it seems that I haven't used interfaces much in the past year, and I seldom use any polymorphism. In fact, the understanding of object-oriented programming is still very vague.　　影片中池松壮亮扮演因为受伤，放弃自己舞蹈生涯的青年照生，伊藤莎莉则扮演出租车司机小叶。影片通过两人的对话，展现出新冠疫情时代的新“恋爱物语”。　　屡告捷，即使在工作上一帆风顺，两人都还是大光棍一个，藉由使用交友网站Match网站，他们都找到了自己迷恋不已的对象，认定可长相厮守，万万没 想到的是，这二位挚友竟然连私事都默契十足，爱上同一人:事业有成女强人的萝拉（瑞茜·威瑟斯彭 Reese Witherspoon 饰）。女主Pitawan出生贫困被母亲卖个上流社会富婆，但是对她又不好，于是她就经常勾搭男人，想让人爱她，后来看上了男主，为了得到男主不惜手段，从他的未婚妻手上抢走他，后来她明白金钱什么的都只是假象，不是真正的幸福，只有真爱才能幸福。　　可怕的是有一条能把任何生物变成石头的恶龙肆虐，为了保卫原始时代的朋友们，喜羊羊他们携手挑战恶龙，懒羊羊更成为了足以改变历史的英雄人物……
