I'm working on a project, that collects some informations to a .CSV file and then send the file to a ftp server.
The program sends the file successfully sometimes, but other times it just stops and throws the error:
An unhandled exception of type 'System.Net.WebException' occurred in System.dll
Additional information: The remote server returned an error: 227 Entering Passive Mode (192,168,10,170,216,244)
Can anyone spot anything, that I have done wrong?
Thanks in advance.
Here is my code
private void sendFile_Click(object sender, EventArgs e)
{
Upload("ftp://100.64.44.12", "UsernameHere", "PasswordHere", #"C:\Users\Kasper\Documents\testFolder\data.csv");
}
public void Upload(string FTPAddress, string username, string password, string filePath)
{
FileStream stream = File.OpenRead(filePath);
byte[] buffer = new byte[stream.Length];
stream.Read(buffer, 0, buffer.Length);
stream.Close();
FtpWebRequest request = (FtpWebRequest)FtpWebRequest.Create(FTPAddress + "/" +
Path.GetFileName(filePath));
request.Method = WebRequestMethods.Ftp.UploadFile;
request.Credentials = new NetworkCredential(username, password);
request.UsePassive = true;
request.UseBinary = false;
request.KeepAlive = true;
StreamReader sourceStream = new StreamReader("testfile.txt");
byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
sourceStream.Close();
request.ContentLength = fileContents.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
MessageBox.Show("Upload File Complete, status {0}", response.StatusDescription);
response.Close();
}
Try setting FtpWebRequest.UsePassive = false

can't upload file to ftp this is my code....
string filename = Path.GetFileName(source);
FtpWebRequest request = (FtpWebRequest)FtpWebRequest.Create(ftp + ftpFolder + filename);
request.Credentials = new NetworkCredential("username", "password");
request.UseBinary = true;
request.Method = WebRequestMethods.Ftp.UploadFile;
request.Proxy = new WebProxy();
FileStream fs = File.OpenRead(source);
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
fs.Close();
Stream ftpstream = request.GetRequestStream();
ftpstream.Write(buffer, 0, buffer.Length);
ftpstream.Close();
File.Delete(source);
always an error is occuring at GetRequestStream() the command is not recognized... how can I overcome this error ?
Any help will be appreciated....
add these two line
request.KeepAlive = false;
request.UsePassive= false;
then also if it is not working check whether your antivirus is blocking FTP
I need to upload text file from local machine to ftp server using c#.
I've tried folowing code but it did't work.
private bool UploadFile(FileInfo fileInfo)
{
FtpWebRequest request = null;
try
{
string ftpPath = "ftp://www.tt.com/" + fileInfo.Name
request = (FtpWebRequest)WebRequest.Create(ftpPath);
request.Credentials = new NetworkCredential("ftptest", "ftptest");
request.Method = WebRequestMethods.Ftp.UploadFile;
request.KeepAlive = false;
request.Timeout = 60000; // 1 minute time out
request.ServicePoint.ConnectionLimit = 15;
byte[] buffer = new byte[1024];
using (FileStream fs = new FileStream(fileInfo.FullPath, FileMode.Open))
{
int dataLength = (int)fs.Length;
int bytesRead = 0;
int bytesDownloaded = 0;
using (Stream requestStream = request.GetRequestStream())
{
while (bytesRead < dataLength)
{
bytesDownloaded = fs.Read(buffer, 0, buffer.Length);
bytesRead = bytesRead + bytesDownloaded;
requestStream.Write(buffer, 0, bytesDownloaded);
}
requestStream.Close();
}
}
return true;
}
catch (Exception ex)
{
throw ex;
}
finally
{
request = null;
}
return false;
}// UploadFile
any suggestions ???
You need to actually send the request by calling GetResponse().
You can also make your code much simpler by calling fs.CopyTo(requestStream).
I tinkered around with a bit ftp code and got the following, which seems to work pretty well for me.
ftpUploadloc is a ftp://ftp.yourftpsite.com/uploaddir/yourfilename.txt
ftpUsername and ftpPassword should be self explanatory.
Finally currentLog is the location of the file you're uploading.
Let me know how this worked out for you, if anyone else has any other suggestions I welcome those.
private void ftplogdump()
{
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(ftpUploadloc);
request.Method = WebRequestMethods.Ftp.UploadFile;
request.Credentials = new NetworkCredential(ftpUsername, ftpPassword);
StreamReader sourceStream = new StreamReader(currentLog);
byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
sourceStream.Close();
request.ContentLength = fileContents.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
// Remove before publishing
Console.WriteLine("Upload File Complete, status {0}", response.StatusDescription);
response.Close();
}
I using the following code to send an excel file to FTP. File is sending, File size is also same. But file contains only spaces.
ftpAddress = "X.X.X.X";
outFilePath = "MyFolder/Sample.xls";
inFilePath = "D:/Hello.xls";
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://" + ftpAddress + "/" + outFilePath);
request.Method = WebRequestMethods.Ftp.UploadFile;
request.UseBinary = true;
request.UsePassive = true;
request.KeepAlive = true;
request.Credentials = new NetworkCredential(userId, password);
//FileStream stream = File.OpenRead(inFilePath);
byte[] fileContents = File.ReadAllBytes(inFilePath);
//byte[] buffer = new byte[stream.Length];
request.ContentLength = fileContents.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();
//Shows confirm message
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
Console.WriteLine(response);
response.Close();
Please help. Thanks in advance.

I'm having some trouble with uploading a file to a FTP server from C#. My code works well on localhost, but on the live environment it keeps giving me a The operation has timed out. exception.
I use the following code:
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(ftpPath + "/orders.csv");
request.UsePassive = true;
request.Credentials = new NetworkCredential(ftpUsername, ftpPassword);
request.Method = WebRequestMethods.Ftp.UploadFile;
request.Timeout = -1;
StreamReader sourceStream = new StreamReader(context.Server.MapPath("~/App_Data/orders.csv"));
byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
sourceStream.Close();
request.ContentLength = fileContents.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();
Where ftpPath is the URL of my FTP server: ftp://myserver.com
Does anyone know what I'm doing wrong here? :-)
Thanks in advance.
Some time we need to download, upload file from FTP server. Here is some example to FTP operation.
For this we need to include one namespace and it is. using System.Net
public void DownloadFile(string HostURL, string UserName, string Password, string SourceDirectory, string FileName, string LocalDirectory)
{
if (!File.Exists(LocalDirectory + FileName))
{
try
{
FtpWebRequest requestFileDownload = (FtpWebRequest)WebRequest.Create(HostURL + "/" + SourceDirectory + "/" + FileName);
requestFileDownload.Credentials = new NetworkCredential(UserName, Password);
requestFileDownload.Method = WebRequestMethods.Ftp.DownloadFile;
FtpWebResponse responseFileDownload = (FtpWebResponse)requestFileDownload.GetResponse();
Stream responseStream = responseFileDownload.GetResponseStream();
FileStream writeStream = new FileStream(LocalDirectory + FileName, FileMode.Create);
int Length = 2048;
Byte[] buffer = new Byte[Length];
int bytesRead = responseStream.Read(buffer, 0, Length);
while (bytesRead > 0)
{
writeStream.Write(buffer, 0, bytesRead);
bytesRead = responseStream.Read(buffer, 0, Length);
}
responseStream.Close();
writeStream.Close();
requestFileDownload = null;
responseFileDownload = null;
}
catch (Exception ex)
{
throw ex;
}
}
}
This was a permission issue. Seems like the FTP user on my webhotel was restricted (somehow) Tried with another FTP with a user with full permissions and it worked.
My Class FTP work fine wtih my FTP server, but not with my client FTP server.
public class UploadToFTP
{
public void UploadFTP(string LeSource, string Desti, string CodeClient)
{
Pers_Conf oConf = LeConf.Get_Config(CodeClient);
// Get the object used to communicate with the server.
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://" + oConf.FtpServer + oConf.FtpChemin +"/" + Desti);
request.Method = WebRequestMethods.Ftp.UploadFile;
// This example assumes the FTP site uses anonymous logon.
request.Credentials = new NetworkCredential(oConf.FtpLogin, oConf.FtpPwd);
request.UseBinary = true;
request.UsePassive = true;
// Copy the contents of the file to the request stream.
StreamReader sourceStream = new StreamReader(LeSource);
byte [] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
sourceStream.Close();
request.ContentLength = fileContents.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
//Console.WriteLine("Upload File Complete, status {0}", response.StatusDescription);
response.Close();
}
}
this line is not work : Stream requestStream = request.GetRequestStream();
Anybody have solution ?
i have change the right into 777.
Thanks you in advance,
