Uploading image to FTP mono for Android

Uploading your pictures saved on the SD Card or taken from your mobile phone camera can be easily uploaded to FTP using mono for android. Below is a short code snipped which does exactly that.
You set the directory to
SDCard / Pictures / MyPics
Provide your FTP host, username and password and uploads the images in your uploades folder on the root on your FTP
var dir = new Java.IO.File(Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryPictures), "MyPics");
string ftpHost = "ftp.myhost.com";
string ftpUser = "username";
string ftpPassword = "password";
if (upload)
{
foreach (string picture in pictures)
{
if (picture != null)
{
string ftpfullpath = "ftp://" + ftphost + "/uploads/" + picture;
FtpWebRequest ftp = (FtpWebRequest)FtpWebRequest.Create(ftpfullpath);
//userid and password for the ftp server
ftp.Credentials = new NetworkCredential(ftpUser, ftpPassword);
ftp.KeepAlive = true;
ftp.UseBinary = true;
ftp.Method = WebRequestMethods.Ftp.UploadFile;
using (FileStream fs = File.OpenRead(dir + "//" + picture))
{
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
fs.Close();
Stream ftpstream = ftp.GetRequestStream();
ftpstream.Write(buffer, 0, buffer.Length);
ftpstream.Close();
}
}
}
}
