VB.NET 从路径中获取目录和子目录

Question

I'm trying to get the full path minus the filename from a path in vb.net. I'm using a textbox and a browse button to get the full path, but I want to save just the directories.

How do I get just the directories and sub-directories?

Example file name:

• c:\Users\jsmith\Desktop\file.aspx

Desired result:

• c:\Users\jsmith\Desktop\

   Protected Sub btnBackupFolderName_Click(sender As Object, e As EventArgs) Handles btnBackupFolderName.Click ' Call ShowDialog. Dim result As DialogResult = openFD.ShowDialog() ' Test result. If result = Windows.Forms.DialogResult.OK Then Dim FileNameText As String = openFD.FileName.ToString() Dim backupFolderName = Path.GetFileName(Path.GetDirectoryName(FileNameText)) 'this just gives me 'Desktop' txtBackupFolder.Text = di.ToString 'backupFolderName End If End Sub

Thank you for your help!

Get the full path of the file and then use GetDirectoryName() to retrieve the folder-path, like this:

Dim openFD As OpenFileDialog = New OpenFileDialog()

Dim result As DialogResult = openFD.ShowDialog()
If result = DialogResult.OK Then
    Dim FileNameText As String = openFD.FileName.ToString()
    ' This gets the folder-path, sans filename.
    txtBackupFolder.Text = Path.GetDirectoryName(openFD.FileName)
End If
