Question

Im having a problem parsing a string array of Directories. The end goal is to query the path tied to the [global].MyDataDir & “\saved” to get all folders in this directory. However the actual foldernames, the last bit of text after the last indexof “\” holds the name of a plugin that I need to compare against an enumerated list of plugins for further functionality I won’t get into here. The problem here is my last bit of code wont work. The Dim foldername as String = (etc…), It returns an error saying Index and length must refer to a location within the string. Parameter name: length.

Can any of you wizards, help me out here. Much appreciated.

Dim dirList As String() = System.IO.Directory.GetDirectories([global].MyDataDir & "\saved")
For dir As Integer = 0 To dirList.Length - 1
    If IO.Directory.GetFiles(dirList(dir)).Length > 0 Then
        For Each file As String In IO.Directory.GetFiles(dirList(dir))

            Dim folderName As String = dirList(dir).ToString.Substring(dirList(dir).ToString.LastIndexOf("\"), dirList(dir).ToString.Length - 1)

        Next
    End If
Next

Semper Fi.

Use System.IO.Path.GetDirectoryName() instead.

Next time use the VB.NET Left() convenience function to avoid getting this wrong.
