I have to upload some files on a FTP who use TLS with my C# application ( .net 3.5 ) With Filezila, no problems.
Now, with my C# code, i have a timeout exception and i really don't know why because all is ok with Filezila.
Here is my code :
public static bool AcceptAllCertificatePolicy(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
return true;
}
public static string Upload_SSL(string filenameSrc)
{
ServicePointManager.ServerCertificateValidationCallback = AcceptAllCertificatePolicy;
FileInfo fileInfSrc = new FileInfo(filenameSrc);
FtpWebRequest reqFTP;
// Create FtpWebRequest object from the Uri provided
if (strDirectory.Trim() != "")
{
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + strHost.Trim() + "/" + strDirectory.Trim() + "/" + fileInfSrc.Name.Trim()));
}
else
{
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + strHost.Trim() + "/" + fileInfSrc.Name.Trim()));
}
reqFTP.EnableSsl = true;
// Provide the WebPermission Credintials
reqFTP.Credentials = new NetworkCredential(strUser.Trim(), strPass.Trim());
reqFTP.Proxy = null;
// By default KeepAlive is true, where the control connection is not closed
// after a command is executed.
reqFTP.KeepAlive = false;
// Specify the command to be executed.
reqFTP.Method = WebRequestMethods.Ftp.UploadFile;
// Specify the data transfer type.
reqFTP.UseBinary = true;
// Notify the server about the size of the uploaded file
reqFTP.ContentLength = fileInfSrc.Length;
// The buffer size is set to 8kb
int buffLength = 8192;
byte[] buff = new byte[buffLength];
int contentLen;
// Opens a file stream (System.IO.FileStream) to read the file to be uploaded
FileStream fs = fileInfSrc.OpenRead();
try
{
// Stream to which the file to be upload is written
Stream strm = reqFTP.GetRequestStream();
// Read from the file stream 2kb at a time
contentLen = fs.Read(buff, 0, buffLength);
// Till Stream content ends
while (contentLen != 0)
{
// Write Content from the file stream to the FTP Upload Stream
strm.Write(buff, 0, contentLen);
contentLen = fs.Read(buff, 0, buffLength);
}
// Close the file stream and the Request Stream
strm.Close();
fs.Close();
}
catch (Exception ex)
{
fs.Close();
return (ex.Message);
}
return "ok";
}
Now, the call :
myFtp.Class1.strHost = "ftp://XXXXXXXXXXXXX";
myFtp.Class1.strPass = "*****************";
myFtp.Class1.strUser = "*********";
myFtp.Class1.nPort = 21;
myFtp.Class1.Upload_SSL(@"D:\Test.txt");
As information, if i try to use my code in order to upload a file on a NON TLS/SLL server, all is ok. So the problem appear to be only for the TLS/SSL ftp.
Anyone have some ideas please ?
Thanks a lot,
