How to get the list of all directories and subdirectories in a specified path using vb.net
My directory structure is like below.
Parent directory
---Sub directory 1 ---Sub directory 2 ------Sub directory2a ------Sub directory2b ---Sub directory 3I am writing in VB.net to fetch a开发者_StackOverflow社区ll the directory names (including sub directories in all the levels)
However while using directory.getfilesystementries(path) I am getting only the top level sub directories. Any idea on how to fetch all the subdirectory names of all sub levels?
just use something like this:
Dim result = System.IO.Directory.EnumerateDirectories(path, "*", System.IO.SearchOption.AllDirectories)
the trick is the SearchOption.AllDirectories
BTW: you can do the same with your GetFileSystemEntries-Method
The Directoryinfo object can provide all sorts of information and about a directory, including directories / Files even system files
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
Dim dir As New DirectoryInfo("C:\")
For Each dirItem As DirectoryInfo In dir.GetDirectories
MsgBox(dirItem.Name)
Next
End Sub
Dim di As New DirectoryInfo(FolderName)
di = New DirectoryInfo(path)
rgFiles = di.GetFiles("*.*", IO.SearchOption.AllDirectories)
For Each fi As FileInfo In rgFiles
If CheckIfExist(fi.FullName.ToString.Replace("\" & fi.Name, "")) = False Then
ListBox1.Items.Add(fi.FullName.ToString.Replace("\" & fi.Name, ""))
End If
Next
Public Function CheckIfExist(ByRef Path As String) As Boolean
Dim RetVal As Boolean = False
For Each LI As String In ListBox1.Items
If LI.ToString = Path Then
RetVal = True
Return RetVal
Exit Function
End If
Next
Return RetVal
End Function
You need to use the overloaded version of Directory.GetFileSystemEntries that specifies whether or not to search subdirectories:
Dim allDirectories As String() = Directory.GetFileSystemEntries("path", "*", SearchOption.AllDirectories)
Directory.GetFileSystemEntries Method (String, String, SearchOption)
