中包含或排除特定文件夹

e.g。我在Directory.GetDirectories()

有4个文件夹

AA
AB
AC
广告

如何仅包含文件夹c:\test1和aa来获取ac或排除Directory.GetDirectories()和ab

ad

你可以尝试检查数组元素的名称。就像

一样

        Dim rootfolder As String
        rootfolder = "c:\test1"
        Dim root As String() = Directory.GetDirectories(rootfolder)
        Dim rootlist As New List(Of String)
        For Each c In root
            If  Path.GetFileName(c) = "aa" Or  Path.GetFileName(c) = "ac" Then  '''' c<>"ab" or c<>"ad"
                rootlist.Add(c)
            End If
        Next
        Dim root1 As String() = rootlist.ToArray()

很高兴，如果它对你有帮助。
