在下刚刚接触.net，在单位实习， 拿着前面师兄得例子作教程，负责作一个办公自动化程序的功能拓展。从控件的使用开始学习，半个月的时间写出了一个页面。我觉的我的模仿能力很好，编程的思想都是在看动别人程序的基础上模仿的，或者用自己在学校学的C语言的思想，再就是考程序员时学到的一些东西；但在写这个页面的过程中我发现了自己在程序流程控制方面的不足，还有就是对类认识的浅显, 函数调用、变量范围控制的基本功也很差，写程序没有一个总的框架，只是想到什么写什么。用到什么看什么方面的内容，只是在有类似例子的情况下才能快速的深入学习一下，没有一个系统的学习计划。很快就大学毕业了，希望自己有质的提高。
希望高手指教：我在这个阶段怎样学习才能快速的成为一个好的程序员。从个人的发展情空间来看，我应该学什么呢。办公自动化程序的发展前景如何？
谢谢！
