WebRequestMethods.Ftp.ListDirectory 找不到文件夹

[itisapity]

使用ListDirectory 只能找到FTP上的文件，就是发现不了文件夹。但是用FileZilla 都可以看到。求大神指教，代码如下：

Dim FTP As FtpWebRequest
Dim Response As FtpWebResponse
Dim lsContent As List(Of String) = New List(Of String)
Dim strContent As String = String.Empty
Try
FTP = FtpWebRequest.Create(New Uri(FTP_FilePath))
FTP.UseBinary = True
FTP.KeepAlive = False
FTP.Method = WebRequestMethods.Ftp.ListDirectory

FTP.Credentials = New NetworkCredential(userName, userPwd)
Response = FTP.GetResponse

Dim content(1024) As Byte
Dim index_a As Integer = 0
Dim bufferLen As Integer = 0
index_a = Response.GetResponseStream.Read(content, 0, content.Length)
bufferLen = bufferLen + index_a

While index_a > 0
index_a = Response.GetResponseStream.Read(content, 0, content.Length)
bufferLen = bufferLen + index_a
End While

strContent = strContent & System.Text.Encoding.UTF8.GetString(content, 0, bufferLen)

MsgBox(strContent)



Dim yu As String = strContent.Replace(vbCrLf, "#").Trim
For Each dir As String In yu.Split("#")
If dir.Trim <> "" Then
lsContent.Add(dir)
End If

Next

Catch ex As Exception
errMsg = ex.Message
Finally
If Response IsNot Nothing Then
Response.Close()
End If
End Try

有木有大神帮忙啊

A)不同服务器对命令的支持不一样。WebRequestMethods.Ftp.ListDirectory 是 NLST，你还可以试试 ls、list 命令。
B)返回格式也可能不同，你是否解析错了？
