以下のコードを含むファイルを から に移動しようとしていftp://a.domain.conます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

問題は、最初の行に

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

エラーが発生しThe given path's format is not supported.ます。

元のファイル名はftp://a.domain.con/102425547_ ��������_14.2.2011_1.zip で、宛先のファイル名は ftp: //b.domain.con/102425547_ ������ です。 ���_14.2.2011_1.zip

ところで、ここに StackTrace が来ます...

   at System.Security.Util.StringExpressionSet.CanonicalizePath(String path, Boolean needFullPath)
   at System.Security.Util.StringExpressionSet.CreateListFromExpressions(String[] str, Boolean needFullPath)
   at System.Security.Permissions.FileIOPermission.AddPathList(FileIOPermissionAccess access, AccessControlActions control, String[] pathListOrig, Boolean checkForDuplicates, Boolean needFullPath, Boolean copyPathList)

   at System.IO.FileStream..ctor(String path, FileMode mode)

そして��������文字はギリシャ文字です！

FileStreamFTPではご利用いただけません。

代わりに、2 つの を作成する必要がありますFtpWebRequest(1 つは読み取り用、もう 1 つは書き込み用)。
