我正在尝试从我的VB.net应用程序上传文件到Mainframe机器。我收到以下错误。

远程服务器返回错误：（501）参数或参数中的语法错误

以下是我的代码。任何帮助将不胜感激。

Dim urlHost As String = "ftp://" + FWFTP.Default.TargetFTPHost.ToString()
    Dim url As String = "ftp://" + FWFTP.Default.TargetFTPHost & "/" & FWFTP.Default.TargetFolder & "/" & fileName
    Dim clsRequest As System.Net.FtpWebRequest = CType(WebRequest.Create(url), FtpWebRequest)

    clsRequest.Credentials = New System.Net.NetworkCredential(FWFTP.Default.FTPUserName.ToString(), FWFTP.Default.FTPPassword.ToString())
    clsRequest.Proxy = Nothing
    Dim target As New Uri(urlHost)
    Dim iphe() As System.Net.IPAddress = System.Net.Dns.GetHostAddresses(target.Host)

    If My.Computer.Network.Ping(iphe(0).ToString, 200) = False Then
        MsgBox("Ping: " + urlHost + ":" + iphe(0).ToString + " Failed")
        'ElseIf FTPSite <> "" Then
    End If
    clsRequest.KeepAlive = False
    clsRequest.UseBinary = False
    clsRequest.UsePassive = True


    clsRequest.Method = System.Net.WebRequestMethods.Ftp.UploadFile

    ' read in file...
    Dim bFile() As Byte = System.IO.File.ReadAllBytes(fullPath)

    ' upload file...
    Dim clsStream As System.IO.Stream = _
        clsRequest.GetRequestStream()
    clsStream.Write(bFile, 0, bFile.Length)
    clsStream.Close()
    clsStream.Dispose()

当你说'大型机'时，任何机会都不会是AS / 400？

当您使用System.Net.WebClient或FtpWebRequest时，如果要访问以下ftp url，请访问Z / Os主机（请注意密码中的@）：

ftp://userid:p@ssword@host/pub/data/msg.log

您必须执行以下操作：

ftp://userid:%40ssword@host/%2Fpub/data/msg.log

这应该适用于下载或上传。
