做ASP.NET项目都会碰到ASP.NET报表问题，中国式报表的繁琐让我很是反感，可没法子啊，客户有需求！自然而然想用DCOM直接操作EXCEL，马马虎虎算是成了，虽说安全性不好，资源浪费严重，毕竟在局域网中使用，凑合吧。
不过总是讨厌在服务端那个没有结束的EXCEL进程……一定要把敌人杀死！google了一把，原来当今中外都有这个ASP.NET报表问题。解决方案也有，Windows XP下搞定，但我在WINDOWS 2003下搞了整整一天也没杀死，得，真想自个杀了。后来有人推荐了个控件ASPOSE解决ASP.NET报表问题，这玩意强，服务端都不用装EXCEL，效果不错！想偷懒的用这玩意，一个字——爽!
