Question

我尝试将'.ics'个文件上传到活动的FTP服务器

命名空间：

Imports System
Imports System.IO
Imports System.Data.OleDb
Imports System.Collections
Imports Microsoft.VisualBasic
Imports System.Net
Imports System.Text

代码：

'Create a FTP Request Object and Specfiy a Complete Path
                Dim reqObj As FtpWebRequest = WebRequest.Create(Ziel + "Calendar/" + MitarbeiterNr + ".ics")
                reqObj.Method = WebRequestMethods.Ftp.UploadFile
                reqObj.UsePassive = False
                reqObj.Credentials = New NetworkCredential(User, Password)
                reqObj.Proxy = Nothing
                reqObj.KeepAlive = False
                reqObj.UseBinary = False
                reqObj.Timeout = 5000


                Dim sourceStream As FileStream = File.OpenRead(AppPath + "Ablage\" + MitarbeiterNr + "\" + MitarbeiterNr + ".ics") ' store file in buffer
                Dim buffer(Convert.ToInt32(sourceStream.Length)) As Byte
                sourceStream.Read(buffer, 0, buffer.Length)
                sourceStream.Close()
                reqObj.ContentLength = buffer.Length
                'Dim objUTF8 As New UTF8Encoding()
                'lblMsg.Text &= objUTF8.GetString(buffer)


                'Upload File and set its object to nothing
                Dim requestStream As System.IO.Stream
                Try
                    requestStream = reqObj.GetRequestStream() 'times out here
                    requestStream.Write(buffer, 0, buffer.Length)
                    requestStream.Close()
                Catch ex As Exception
                    Debug.printMeldung(ex.Message & ex.Source & ex.StackTrace)
                End Try


                reqObj = Nothing

使用过的用户拥有写作等所需的权利。 URI看起来像

ftp://Serveradress/Calendar/filename.ics

以下是我requestStrem = reqObj.GetRequestStream()收到的错误消息：

Der Remoteserver hat einenFehlerzurückgegeben（550）Datei nicht verfügbar（z.B。nicht gefunden oder kein Zugriff）.System bei System.Net.FtpWebRequest.SyncRequestCallback（Object obj）bei System.Net.FtpWebRequest.RequestCallback（Object obj）bei System.Net.CommandStream.InvokeRequestCallback（Object obj）bei System.Net.CommandStream.Abort（Exception e）bei System.Net.FtpWebRequest.FinishRequestStage（RequestStage阶段）bei System.Net.FtpWebRequest.GetRequestStream（）bei DVisualStudio中的Calendar.Calendar.Upload（String MitarbeiterNr） 2008CalendarCalendarCalendar.vbZeile 240。

很抱歉这是德语，但我想你们大多数人都可以阅读; - ）

我从这里抓住了代码

如果有人帮助我尽快解决问题会很高兴=）

始终检查在主机名之后和路径之前放置双斜杠的FTP连接字符串，例如ftp.mickeymouse // htdocs中/文件名。

当我有一个斜线maqrk时，我收到了一条完全没有帮助的错误550消息。

解决了我的问题，虽然这可能与此无关。
