1、微軟提供的操作資料夾系統類 io.directory 和 io.directoryInfo。兩者作用基本一致，功能大體相當，區別在於前者類似於靜態函式，後者類似於類（需要例項化）

舉例：

Dim dirs As String() = IO.Directory.GetDirectories(aimPath, IO.SearchOption.AllDirectories)       

Dim di As IO.DirectoryInfo = New IO.DirectoryInfo(aimPath)
Dim dirs() As IO.DirectoryInfo = di.GetDirectories("*", IO.SearchOption.AllDirectories)
For Each tmpDir As IO.DirectoryInfo In dirs
	Dim attr As String = tmpDir.Attributes.ToString
Next
 

IO.Directory.GetDirectories       '如果遇到隱藏資料夾或system資料夾可能出錯或報錯

 IO.DirectoryInfo
