編寫一個文件目錄常用操作的類

2013-11-13 09:55:19  來源: .NET編程 

  今天對自己以前寫的一些常用的組件整理了一下發現對文件目錄的操作的一個類還用的比較多於是對他進行了修改一些方法是為在社區中看到有網友提問增加的包括復制目錄的文件和子目錄移動目錄文件和子目錄生成Xml樹形文件等

  using SystemIO;

  using SystemXml;

  }

  }

  }

  整個類比較簡單沒有寫相關的查找文件目錄的方法對異常沒有處理我認為如果有異常拋出還是在這個類外面處理更好如果有網友使用發現問題請聯系我或在BLOG上留言另外在測試這個類的時候發現了一個Bug不知道是 windows系統的 framework的bug
