}
}

Wie zu verwenden

UploadFtpFile("testFolder", "E:\\filesToUpload\\test.img");

verwenden Sie diese in Ihrem foreach

und Sie müssen nur Ordner erstellen, eine Zeit

einen Ordner zu erstellen,

request = WebRequest.Create(new Uri(string.Format(@"ftp://{0}/{1}/", "127.0.0.1", "testFolder"))) as FtpWebRequest;
request.Method = WebRequestMethods.Ftp.MakeDirectory;
FtpWebResponse ftpResponse = (FtpWebResponse)request.GetResponse();

Im ersten Beispiel zu ändern, müssen diese an:

requestStream.Flush();
requestStream.Close();

First flush und danach schließen.

Ich habe beobachtet, dass -

1. FtpwebRequest fehlt.
2. Als Ziel ist FTP, so der NetworkCredential-erforderlich.

Vorbereitet habe ich eine Methode, wie das funktioniert, können Sie ersetzen Sie den Wert der variable ftpurl mit dem parameter TargetDestinationPath. Hatte ich getestet, diese Methode auf winforms-Anwendung :

private void UploadProfileImage(string TargetFileName, string TargetDestinationPath, string FiletoUpload)
        {
            //Get the Image Destination path
            string imageName = TargetFileName; //you can comment this
            string imgPath = TargetDestinationPath; 

            string ftpurl = "ftp://downloads.abc.com/downloads.abc.com/MobileApps/SystemImages/ProfileImages/" + imgPath;
            string ftpusername = krayknot_DAL.clsGlobal.FTPUsername;
            string ftppassword = krayknot_DAL.clsGlobal.FTPPassword;
            string fileurl = FiletoUpload;

            FtpWebRequest ftpClient = (FtpWebRequest)FtpWebRequest.Create(ftpurl);
            ftpClient.Credentials = new System.Net.NetworkCredential(ftpusername, ftppassword);
            ftpClient.Method = System.Net.WebRequestMethods.Ftp.UploadFile;
            ftpClient.UseBinary = true;
            ftpClient.KeepAlive = true;
            System.IO.FileInfo fi = new System.IO.FileInfo(fileurl);
            ftpClient.ContentLength = fi.Length;
            byte[] buffer = new byte[4097];
            int bytes = 0;
            int total_bytes = (int)fi.Length;
            System.IO.FileStream fs = fi.OpenRead();
            System.IO.Stream rs = ftpClient.GetRequestStream();
            while (total_bytes > 0)
            {
                bytes = fs.Read(buffer, 0, buffer.Length);
                rs.Write(buffer, 0, bytes);
                total_bytes = total_bytes - bytes;
            }
            //fs.Flush();
            fs.Close();
            rs.Close();
            FtpWebResponse uploadResponse = (FtpWebResponse)ftpClient.GetResponse();
            string value = uploadResponse.StatusDescription;
            uploadResponse.Close();
        }
