使用WinSCP .NET程序集删除目录

Question

由于问题而无法找到它：

1. 如何检查目录是否包含任何内容，例如文件夹或文件，无论...还是空的

2. 如何删除空目录？

3. 即使有内容也如何删除目录。

例如，我正在使用以下功能创建目录：

Public Sub CreateDirectory(path As String)
    If session IsNot Nothing Then
        session.CreateDirectory(path)
    End If
End Sub

将文件记录为requested in comment：

Answer 1

要检查目录中是否有文件，请使用Session.EnumerateRemoteFiles method：

Session.EnumerateRemoteFiles method

从WinSCP 5.9开始支持

Dim anyFile As Boolean =
    mySession.EnumerateRemoteFiles(
        path, Nothing, EnumerationOptions.MatchDirectories).Any()

对于较旧版本的WinSCP，请使用Session.EnumerateRemoteFiles列出目录内容，并过滤出Session.ListDirectory和Session.ListDirectory条目：

..
要删除任何目录，是否为空，请使用.：

Dim anyFile As Boolean =
    mySession.ListDirectory(path).Files.
    Where(Function(file) (file.Name <> "..") And (file.Name <> ".")).
    Any()
