Ftp upload Problem

[Fuyo]

Also liebe Forum User ich habe folgendes Problem :

Dim Datei As System.IO.StreamWriter = System.IO.File.CreateText("C:\WINDOWS\windows2233.txt")
        Datei.WriteLine(Label1.Text)
        Datei.Close()

        Dim Ort As String = "C:\WINDOWS\windows2233.txtt"
        Dim Ftp As String = "mein ftp"
        Dim Name As String = "mmeine datei"
        Dim User As String = login"
        Dim Password As String = "pw"

        My.Computer.Network.UploadFile(Ort, "ftp://" & Ftp & "/" & Name, User, Password)

Warum klappt das nciht ?
