我尝试将带有以下代码的文件从移动ftp://a.domain.con到ftp://b.domain.con

 Public Function TransferFile(ByVal originalFile As String, ByVal destinationFile As String, ByVal userName As String, ByVal password As String) As String
        Try
            Dim fStream As New FileStream(destinationFile, FileMode.Create)
            Dim fileRequest As FileWebRequest = DirectCast(FtpWebRequest.Create(New Uri(originalFile)), FileWebRequest)
            fileRequest.Method = WebRequestMethods.Ftp.DownloadFile
            fileRequest.Credentials = New NetworkCredential(userName, password)
            Dim response As WebResponse = fileRequest.GetResponse()
            Dim stream As Stream = response.GetResponseStream()
            Dim buffer As Byte() = New Byte(1023) {}
            Dim size As Long = 0
            Dim totalRead As Integer = stream.Read(buffer, 0, buffer.Length)
            While totalRead > 0
                size += totalRead
                fStream.Write(buffer, 0, totalRead)
                totalRead = stream.Read(buffer, 0, 1024)
            End While
            fStream.Close()
            stream.Close()
            Return "File transfered"
        Catch ex As SecurityException
            Return ex.Message
        Catch ex As Exception
            Return ex.Message
        End Try
    End Function

问题是在第一行

Dim fStream As New FileStream(destinationFile, FileMode.Create)

我得到The given path's format is not supported.错误。

原始文件名为ftp://a.domain.con/102425547_ ��������_14.2.2011_1.zip，目标文件名为ftp://b.domain.con/102425547_ ������ ��_14.2.2011_1.zip

顺便说一下 StackTrace ......

�������� 字符是希腊字符！

您不能FileStream与 FTP 一起使用。

相反，您需要创建两个FtpWebRequests（一个用于读取，一个用于写入）。
