Get File Size from FTP (in SSIS, using Dts.Connections)

I have an issue sending big file to an FTP site and I would like to check the file size after the transfer (sometimes it works sometimes it fails). The transfer is within an SSIS and I'm using Dts.Connections in C#.
My code:
public long TransferFile(string file)
{
long filesize = 0L;
try
{
string[] newfile = new[] { file };
ConnectionManager ftpCM = Dts.Connections["ftp_server"];
string remoteDir = Dts.Variables["FtpWorkingDirectory"].Value.ToString();
FtpClientConnection ftpClient = new FtpClientConnection(ftpCM.AcquireConnection(null));
ftpClient.UsePassiveMode = true;
ftpClient.Connect();
ftpClient.Retries = 10;
ftpClient.SetWorkingDirectory(remoteDir);
ftpClient.SendFiles(newfile, remoteDir, true, false);
ftpClient.Close();
}
catch (Exception ex)
{
throw ex;
}
return filesize;
}
I found examples using FtpWebRequest but I don't have the ftp uri available so I don't see how to use this method. How can I get this file size?
UPDATE:
Adding this:
FtpWebRequest request = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpCM.ConnectionString + remoteDir + "/" + file));
request.Proxy = null;
DtsProperty ServerUsername = ftpCM.Properties["ServerUserName"];
DtsProperty ServerPassword = ftpCM.Properties["ServerPassword"];
request.Credentials = new NetworkCredential(ServerUsername.GetValue(ftpCM).ToString(), ServerPassword.GetValue(ftpCM).ToString());
request.Method = WebRequestMethods.Ftp.GetFileSize;
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
filesize = response.ContentLength;
response.Close();
I get error: The property ServerPassword is write-only.

The final solution was to store the username and password in Variables instead of connection parameters.
And with the following code:
public long TransferFile(string file)
{
long filesize = 0L;
try
{
string[] newfile = new[] { file };
ConnectionManager ftpCM = Dts.Connections["ftp_server"];
string remoteDir = Dts.Variables["FtpWorkingDirectory"].Value.ToString();
string ServerUsername = Dts.Variables["ServerUsername"].Value.ToString();
string ServerPassword = Dts.Variables["ServerPassword"].Value.ToString();
FtpClientConnection ftpClient = new FtpClientConnection(ftpCM.AcquireConnection(null));
ftpClient.UsePassiveMode = true;
ftpClient.ServerUserName = ServerUsername;
ftpClient.ServerPassword = ServerPassword;
ftpClient.Connect();
ftpClient.Retries = 10;
ftpClient.SetWorkingDirectory(remoteDir);
ftpClient.SendFiles(newfile, remoteDir, true, false);
ftpClient.Close();
FtpWebRequest request = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpCM.ConnectionString + remoteDir + "/" + Path.GetFileName(file)));
request.Proxy = null;
request.Credentials = new NetworkCredential(ServerUsername, ServerPassword);
request.Method = WebRequestMethods.Ftp.GetFileSize;
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
filesize = response.ContentLength;
response.Close();
}
catch (Exception ex)
{
throw ex;
}
return filesize;
}

Can't reinstall service

I am trying to create an auto update for an application however I am having a bit of trouble with the updating part. Basically what I have is a windows service that periodically checks for updates and when it finds and update it launches a console application to update itself. The code for the console application is below.
The problem I'm having is that when I uninstall the service and replace the file that drives the service, I get a system.badimageformat exception. Despite reinstalling an identical file. If I uninstall and re-install the file without downloading it and replacing it from FTP there is no issue, but as soon as I change the file it starts giving me exceptions. Does anyone have any ideas on how I can work around this error. I am confident its not a 32 vs 64 bit issue which is what commonly causes this error.

The main problem is that you treat the files as text files:
string[] temp = reader.ReadToEnd().Split(new string[] { Environment.NewLine }, StringSplitOptions.None);
....
File.WriteAllLines(DesktopFile, temp);
You can use this instead:
Stream responseStream = response.GetResponseStream();
...
using (FileStream destStream = File.Create(DesktopFile))
{
responseStream.CopyTo(destStream);
}
responseStream.Close();
response.Close();
However, this is still not the best solution, since you should use the pattern
using (X123 x123 = new X123(y))
{
// do something with x123
}
for all classes which support IDisposable.
In addition, I have some concerns about using Sleep() in so many situations. This is seldom a good idea.

C# Ftp Error - Null reference

I have this code which works perfect when there is a file on FTP site , but when there is no file on FTP site it fails.
The error II get is in foreach (string file in files) and it says there is null reference .
How can I fix this so that if there is no file on FTP site this code will work.
Thanks in advance.

You need to test the result of GetFilesList() for null, because you return null in case an error (in catch clause of GetFileList() you set the result - downloadFiles - to null).
public void Main()
{
String[] files = GetFileList();
if (files != null) // add this line
{
foreach (string file in files)
{
Download(file);
}
}

Problem is your call to GetFileList returns null and thus the foreach fails.

Retry mechanism for downloading files

I have created a function that find files on a FTP folder.
public static List<string> GetFileList(NetworkCredential credential, string FTPSite, string FTPFolder, string extension)
{
string LSOutput = "";
List<string> files = new List<string>();
//Fetch LS
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(#"ftp://" + FTPSite + FTPFolder);
request.Credentials = credential;
request.UseBinary = true;
request.EnableSsl = true;
request.Method = WebRequestMethods.Ftp.ListDirectory;
FtpWebResponse response = null;
response = (FtpWebResponse)request.GetResponse();
Stream responseStream = response.GetResponseStream();
StreamReader reader = new StreamReader(responseStream);
LSOutput = reader.ReadToEnd();
reader.Close();
response.Close();
PrepareLog("LS output while finding files:");
PrepareLog(LSOutput);
//Parse the LS
string[] LSOutputLines = LSOutput.Trim().Split(new string[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries);
foreach (string LSOutputLine in LSOutputLines)
files.Add(LSOutputLine);
//Filter files
files = files.Where(f => f.ToLower().EndsWith(extension.ToLower())).ToList();
PrepareLogAndEmail("Total " + extension.ToLower() + " files found: " + files.Count, LogMessageType.Simple);
return files;
}
Exception handling is done at the place where the function is being called.
Now the problem is that sometimes the FTP faces some issues(like timeout) and then we have to rerun the program.
I have been asked to add 3 times retry mechanism and here is what I did to retry it once.
public static List<string> GetFileList(NetworkCredential credential, string FTPSite, string FTPFolder, string extension)
{
string LSOutput = "";
List<string> files = new List<string>();
try
{
//Fetch LS
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(#"ftp://" + FTPSite + FTPFolder);
request.Credentials = credential;
request.UseBinary = true;
request.EnableSsl = true;
request.Method = WebRequestMethods.Ftp.ListDirectory;
FtpWebResponse response = null;
response = (FtpWebResponse)request.GetResponse();
Stream responseStream = response.GetResponseStream();
StreamReader reader = new StreamReader(responseStream);
LSOutput = reader.ReadToEnd();
reader.Close();
response.Close();
PrepareLog("LS output while finding files:");
PrepareLog(LSOutput);
}
catch (Exception ex)
{
PrepareLogAndEmail("First attempt failed: Details: " + ex.Message, LogMessageType.AttemptFailed);
PrepareLogAndEmail("Second attempt started" + ex.Message, LogMessageType.Simple);
//Fetch LS
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(#"ftp://" + FTPSite + FTPFolder);
request.Credentials = credential;
request.UseBinary = true;
request.EnableSsl = true;
request.Method = WebRequestMethods.Ftp.ListDirectory;
FtpWebResponse response = null;
response = (FtpWebResponse)request.GetResponse();
Stream responseStream = response.GetResponseStream();
StreamReader reader = new StreamReader(responseStream);
LSOutput = reader.ReadToEnd();
reader.Close();
response.Close();
PrepareLog("LS output while finding files(second attempt):");
PrepareLog(LSOutput);
}
//Parse the LS
string[] LSOutputLines = LSOutput.Trim().Split(new string[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries);
foreach (string LSOutputLine in LSOutputLines)
files.Add(LSOutputLine);
//Filter files
files = files.Where(f => f.ToLower().EndsWith(extension.ToLower())).ToList();
PrepareLogAndEmail("Total " + extension.ToLower() + " files found: " + files.Count, LogMessageType.Simple);
return files;
}
Now if I have to add 2 more tries, will I need to do this sort of daiys chaining or is there any other cleaner option available ?

I would go with a retry loop, something like below
You will notice that I make use of a bolean to flag out of a successfull download, or the retries count to terminate.
I would even go as far as changing the last section to check if the download was successfull, and notify the user if it was not, Maybe even logging the error messages.
public static List<string> GetFileList(NetworkCredential credential, string FTPSite, string FTPFolder, string extension)
{
List<string> files = new List<string>();
int retries = 0;
int maxRetries = 5;
bool downloaded = false;
string LSOutput = "";
while (!downloaded && retries < maxRetries)
{
try
{
LSOutput = "";
//Fetch LS
FtpWebRequest request = (FtpWebRequest) WebRequest.Create(#"ftp://" + FTPSite + FTPFolder);
request.Credentials = credential;
request.UseBinary = true;
request.EnableSsl = true;
request.Method = WebRequestMethods.Ftp.ListDirectory;
FtpWebResponse response = null;
response = (FtpWebResponse) request.GetResponse();
Stream responseStream = response.GetResponseStream();
StreamReader reader = new StreamReader(responseStream);
LSOutput = reader.ReadToEnd();
reader.Close();
response.Close();
PrepareLog("LS output while finding files:");
PrepareLog(LSOutput);
downloaded = true;
}
catch (Exception ex)
{
retries++;
}
}
if (downloaded)
{
//Parse the LS
string[] LSOutputLines = LSOutput.Trim().Split(new string[] {Environment.NewLine}, StringSplitOptions.RemoveEmptyEntries);
foreach (string LSOutputLine in LSOutputLines)
files.Add(LSOutputLine);
//Filter files
files = files.Where(f => f.ToLower().EndsWith(extension.ToLower())).ToList();
PrepareLogAndEmail("Total " + extension.ToLower() + " files found: " + files.Count, LogMessageType.Simple);
return files;
}
else
{
PrepareLogAndEmail("Failed to download file", LogMessageType.Simple);
return null;
}
}

How do I pull the file locations (path and filename) for all files at a given FTP address?

Hi and thanks for looking!
Background
I need to pull the file locations (path and filename) for all files at a given FTP address.
For files on a mapped network or local drive, this code would work:
foreach(string fileName f in Directory.GetFiles("C\\:SomeDirectory"), "*.*",
SearchOption.AllDirectories)
{
//do stuff with each file found
}
But this will NOT work over an FTP connection. I have already found this MS documentation which covers the establishing of an FTPWebRequest, but it does not show me how to loop through each file found (in all nested directories as well).
I am using C# within a forms app.
Question
How do I accomplish this:
foreach(string fileName f in Directory.GetFiles("C\\:SomeDirectory"), "*.*",
SearchOption.AllDirectories)
{
//do stuff with each file found
}
With an FTP connection?
Many thanks!!
UPDATE / Final Answer
Special thanks to #sunk for getting this going. I made a minor tweek to his code that makes it fully recursive so that it can drill into nested folders. Here is the final code:
//A list that holds all file locations in all folders of a given FTP address:
List<string> fnl= new List<string>();
//A string to hold the base FTP address:
string ftpBase = "ftp://[SOME FTP ADDRESS]";
//A button-click event. Can be a stand alone method as well
private void GetFileLocations(object sender, EventArgs e)
{
//Get the file names from the FTP location:
DownloadFileNames(ftpBase);
//Once 'DownloadFileNames' has run, we have populated 'fnl'
foreach(var f in fnl)
{
//do stuff
}
}
//Gets all files in a given FTP address. RECURSIVE METHOD:
public void DownloadFileNames(string ftpAddress)
{
string uri = ftpAddress;
FtpWebRequest reqFTP = (FtpWebRequest)FtpWebRequest.Create(uri);
reqFTP.Credentials = new NetworkCredential("pella", "PellaWA01!");
reqFTP.EnableSsl = false;
reqFTP.KeepAlive = false;
reqFTP.UseBinary = true;
reqFTP.UsePassive = true;
reqFTP.Method = WebRequestMethods.Ftp.ListDirectory;
FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
Stream responseStream = response.GetResponseStream();
List<string> files = new List<string>();
StreamReader reader = new StreamReader(responseStream);
while (!reader.EndOfStream)
files.Add(reader.ReadLine());
reader.Close();
responseStream.Dispose();
//Loop through the resulting file names.
foreach (var fileName in files)
{
var parentDirectory = "";
//If the filename has an extension, then it actually is
//a file and should be added to 'fnl'.
if (fileName.IndexOf(".") > 0)
{
fnl.Add(ftpAddress.Replace("ftp://pella.upload.akamai.com/140607/pella/", "http://media.pella.com/") + fileName);
}
else
{
//If the filename has no extension, then it is just a folder.
//Run this method again as a recursion of the original:
parentDirectory += fileName + "/";
try
{
DownloadFileNames(ftpAddress + parentDirectory);
}
catch (Exception)
{
//throw;
}
}
}
}

First of all, you have to get the files name local on your machine using FTPWebRequest.
WebRequestMethods.Ftp.ListDirectory;
then use foreach {};
Here is the code:-
public List<string> DownloadFileNames()
{
string uri = "ftp://" + ftpServerIP + "/";
FtpWebRequest reqFTP = (FtpWebRequest)FtpWebRequest.Create(uri);
reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
reqFTP.EnableSsl = true;
reqFTP.KeepAlive = false;
reqFTP.UseBinary = true;
reqFTP.UsePassive = Settings.UsePassive;
reqFTP.Method = WebRequestMethods.Ftp.ListDirectory;
ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications);
FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
Stream responseStream = response.GetResponseStream();
List<string> files = new List<string>();
StreamReader reader = new StreamReader(responseStream);
while (!reader.EndOfStream)
files.Add(reader.ReadLine());
reader.Close();
responseStream.Dispose();
return files;
}
Now you have the List:-
List<string> FileNameList = DownloadFileNames();
foreach (var fileName in FileNameList)
{
}

the ListDirectoryDetails command used in the example just returns a string. You will have to manually parse it to build a list of files and subdirectories.
