[原创]C# 文件查找~~ ^_^
william
如果大家需要.留下email.我打包发给你们.
----------------------------------------------------------------------------------------------------------
我这里提供了几个查找的方法,通过线路号,通过录音时间,通过录音时长(未完成)
未完成的内个也是郁闷了我最久的..........
我所有的查帐根据都是语音文件的文件名,也就是说,后台的程序生成的是有特定格式的文件名的录音文件.我这里的格式是
// 2005-12-13-09-04-03-6
// y m d h m s 线路号
以下是按线路好查帐的页面代码和查找文件的类

其实做其他格式的查找也是如此...........
过短时间我加以改进下,应该可以实现全部格式的文件扫描````
啊``````我又在乱想了``````````哈哈``````
期待指教`````^_^
