Vb.net 获取a侧目录中的所有文件夹和子文件夹

我正在学习VB.net，我想知道如何获取目录中的所有文件夹和子文件夹，以及如何将它们全部添加到列表框中。我也希望它列出的文件夹，而它是扫描一样，显示当前找到的文件夹。我试过一些方法，但似乎都不管用。我试过这个：

Sub GetDirectories(ByVal StartPath As String, ByRef DirectoryList As ArrayList)
    Dim Dirs() As String = Directory.GetDirectories(StartPath)
    DirectoryList.AddRange(Dirs)
    For Each Dir As String In Dirs
        GetDirectories(Dir, DirectoryList)
    Next
    For Each item In DirectoryList
        ListBox1.Items.Add(item)
    Next
End Sub

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Dim DirList As New ArrayList
    GetDirectories("c:\hexing\", DirList)
End Sub

使用该方法

试试这个

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Try
    Dim DirList As New ArrayList
    Dim Dirs() As String = Directory.GetDirectories(StartPath)
    DirList.AddRange(Dirs)
    For Each Dir As String In Dirs
        GetDirectories(Dir, DirectoryList)
    Next
    Catch ex As Exception
End Try
End Sub

（或）

编辑

根据：

最有效的方法是使用递归性：

最简单的是：

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
    GetDirectories(Label1.Text)
End Sub

Sub GetDirectories(ByVal StartPath As String)
    For Each Dir As String In IO.Directory.GetDirectories(StartPath)
        CheckedListBox1.Items.Add(Dir)
        GetDirectories(Dir)
    Next
End Sub

第二个没有得到所有的文件夹，我希望它得到主目录中的所有文件夹，然后得到这些文件夹中的所有子文件夹。谢谢anyway@xGh0stSn1p3r请参阅我的编辑。它会给你所有的子文件夹，但在一开始，它会冻结，只是停留在那里一段时间，不能移动它或任何东西。有没有办法在后台运行它，以便您仍然可以移动表单？或者甚至在每次找到一个目录时将每个目录添加到列表框中，而不是仅仅停留在那里？谢谢编辑*在ListBox上它只显示string[]数组。我已经尝试过了，它可以工作，但是它没有得到目录中的子文件夹，我希望它能得到每个文件夹中的每个子文件夹。感谢anywaLooks，像您这样的人在第一行代码的开头短了3个空格（但我无法修复它，因为编辑必须至少6个字符）。

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        For Each Dir As String In Directory.GetDirectories("c:\Program Files")
            ListBox1.Items.Add(Dir)
        Next
End Sub

 Private Function getAllFolders(ByVal directory As String) As String()
        'Create object
        Dim fi As New IO.DirectoryInfo(directory)
        'Array to store paths
        Dim path() As String = {}
        'Loop through subfolders
        For Each subfolder As IO.DirectoryInfo In fi.GetDirectories()
            'Add this folders name
            Array.Resize(path, path.Length + 1)
            path(path.Length - 1) = subfolder.FullName
            'Recall function with each subdirectory
            For Each s As String In getAllFolders(subfolder.FullName)
                Array.Resize(path, path.Length + 1)
                path(path.Length - 1) = s
            Next
        Next
        Return path
 End Function

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
    GetDirectories(Label1.Text)
End Sub

Sub GetDirectories(ByVal StartPath As String)
    For Each Dir As String In IO.Directory.GetDirectories(StartPath)
        CheckedListBox1.Items.Add(Dir)
        GetDirectories(Dir)
    Next
End Sub
