记得当初开师徒会的时候,谈到进度时,师父学到C#,大伟做会议记录,我俩都不知道怎么写,我们大瞪小的,最后只好请教师父,现在自己也学习了C#,有点小激动!在视频中除了讲到C#外,还简单的提了一下UML和设计模式上的知识,看到视频中讲的UML就有种熟悉感
记得当初开师徒会的时候,谈到进度时,师父学到C#,大伟做会议记录,我俩都不知道怎么写,我们大眼瞪小眼的,最后只好请教师父,现在自己也学习了C#,有点小激动!在视频中除了讲到C#外,还简单的提了一下UML和设计模式上的知识,看到视频中讲的UML就有种熟悉感,看到视频中将设计模式就有种兴奋感,早就听说设计模式是一本很有意思的书,设计模式又出现在这个视频的最后,这个期待呀。不过还是先来总结一下C#,再谈设计模式。
数据库中的触发器,当程序运行到某个步骤的时候,触发这个事件。
小小的C#总结,看的时候挺有感觉的,但是一总结,就出现问题了,于是各种找资料,找博客,看看前辈们是怎么写的,有点厘头以后才提笔写起总结。简单的思维导图是对C#的简单认识,很多东西都还没有连起来,一点点的消化吧!
