很久没有写了，原因很简单没有想起来，够简单粗暴吧，好吧承认都是借口
—————————————————我是分界线哦————————————————————————
昨天GIS程序与开发课结束了它的完整生命周期，老师让我们每个人做个总结。学号最后一个，便最后一个总结。
课程上完，最大感受，嗯，我又学会了怎么拼代码！老师给我说了我的优缺点，可能当时没反应过来，今天早上才反应过来
，所以写下该文。工作做的很多，成果别人看不到，自己学到的帮助其他同学，自己却不能从他们那获得有用的知识，这也是要求我多总结
，并且是阶段性的总结。那就列一下自己课程代码吧，项目名称：《道路分析系统》，基于vs2010(C#开发)+ArcEngine10.2+ArcGIS10.2
虽然我是代码搬运工，但我不在乎啊。
