本文介绍如何利用C#中的Directory类进行文件夹的基本操作，包括创建、删除、获取当前目录、获取根目录等，并提供了查找子目录、文件及文件系统条目的示例代码。

Imports System.IO

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Directory.CreateDirectory("c:\dyc") '创建目录

If Directory.Exists("c:\dyc") Then
Directory.Delete("c:\dyc") '删除目录
End If

MsgBox(Directory.GetCurrentDirectory) '当前应用程序目录
MsgBox(Directory.GetDirectoryRoot("c:\windows\system32")) '根目录
'MsgBox(Directory.GetParent("c:\windows\system32")) '父目录
MsgBox(Directory.GetCreationTime("c:\windows\system32")) '目录创建的时间、时间

REM 查找子目录
Dim dirs() As String = Directory.GetDirectories("c:\windows")
For i = 0 To dirs.Length - 1
Debug.Print(dirs(i))
Next

REM 查找文件
Dim files() As String = Directory.GetFiles("c:\windows")
For i = 0 To files.Length - 1
Debug.Print(files(i))
Next

REM 查找子目录和文件
Dim dirfiles() As String = Directory.GetFileSystemEntries("c:\windows")
For i = 0 To dirfiles.Length - 1
Debug.Print(dirfiles(i))
Next

End Sub
End Class

精典使用案例：

Imports System.IO

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim dirs() As String = Directory.GetDirectories("c:\")
Dim files() As String = Directory.GetFiles("c:\")
Dim dirfiles() As String = Directory.GetFileSystemEntries("c:\")
Dim dris() As String = Directory.GetLogicalDrives()

For Each temp As String In dirs
ListBox1.Items.Add(temp)
Next

For Each temp As String In files
ListBox2.Items.Add(temp)

For Each temp As String In dirfiles
ListBox3.Items.Add(temp)

For Each temp As String In dris
ListBox4.Items.Add(temp)

Next
End Sub
End Class
