当然，等到讲完了目录操作后，我将会举个类似于资源管理器的例子。
窗体设计界面如下：
列出子目录：
Private Sub btnSubFolders_Click(sender As Object, e As EventArgs) Handles btnSubFolders.Click Dim di As New DirectoryInfo("c:\windows") If di.Exists = False Then Exit Sub txtFolderInfo.Text = "" For Each folderinfo As DirectoryInfo In di.GetDirectories txtFolderInfo.Text &= folderinfo.Name & ControlChars.CrLf Next End Sub为简化操作，直接使用的Windows目录。
列出目录下的文件：
Private Sub btnFiles_Click(sender As Object, e As EventArgs) Handles btnFiles.Click Dim di As New DirectoryInfo("c:\windows") If di.Exists = False Then Exit Sub txtFolderInfo.Text = "" For Each finfo As FileInfo In di.GetFiles txtFolderInfo.Text &= finfo.Name & ControlChars.CrLf Next End Sub提前用了点FileInfo的知识。
列出所有：
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click Dim di As New DirectoryInfo("c:\windows") If di.Exists = False Then Exit Sub Dim fsType As String txtFolderInfo.Text = "" For Each fsinfo As FileSystemInfo In di.GetFileSystemInfos If (fsinfo.Attributes And FileAttribute.Directory) = FileAttribute.Directory Then fsType = "目录" Else fsType = "文件" txtFolderInfo.Text &= fsType & " " & fsinfo.Name & ControlChars.CrLf Next End Sub其实，DirectoryInfo和FileInfo都是继承于FileSystemInfo，很多属性和方法都来自FileSystemInfo。
运行时如图：
