README.md FluentFTP FluentFTP is a fully managed FTP and FTPS library for.NET &.NET Standard, optimized for speed. It provides extensive FTP commands, File uploads/downloads, SSL/TLS connections, Automatic directory listing parsing, File hashing/checksums, File permissions/CHMOD, FTP proxies, UTF-8 support, Async/await support and more. It is written entirely in C#, with no external dependencies. FluentFTP is released under the permissive MIT License, so it can be used in both proprietary and free/open source applications.
Client.Credentials = new NetworkCredential( 'anonymous ', 'anonymous '); How do I login with an FTP proxy? Create a new instance of FtpClientHttp11Proxy or FtpClientUserAtHostProxy and use FTP properties/methods like normal. How can I track the progress of file transfers? All of the provide a progress argument that can be used to track upload/download progress.
First create and configure a ProgressBar such that the Minimum is 0 and Maximum is 100. Then create a callback to provide to the Upload/Download method. This will be called with a value, where 0 to 100 indicates the percentage transfered, and -1 indicates unknown progress. Client.DownloadFile(localPath, remotePath, true, FluentFTP.FtpVerify.Retry, progress); For.NET 2.0 users, pass an implementation of the IProgress class. The Report() method of the object you pass will be called with the progress value.
How can I upload data created on the fly? 7 Days To Die Alpha 2 Crack Download there. Use Upload() for uploading a Stream or byte.
I am trying to download not one, but all files within a remote directory using FTP and C# and then save them to a local folder on my hard drive. I have been using.NET/.NET CF FTP Component (link to componentforge removed) for my File Transfer needs. I hope this helps. The FTP component from. NET Framework. The FileSystemWatcher object allows you to monitor changes within a directory, specifically when files or folders are created, modified. NET 3.5 SP1 and.NET 4 runtimes; the SharpDevelop download page provides links to the required.NET runtime downloads on the Microsoft Download Center website.
How can I download data without saving it to disk? Use Download() for downloading to a Stream or byte.
How can I throttle the speed of upload/download? Set the UploadRateLimit and DownloadRateLimit properties to control the speed of data transfer. Only honored by the, for both the synchronous and async versions, such as: • Upload() / Download() • UploadFile() / DownloadFile() • UploadFiles() / DownloadFiles() How do I verify the hash/checksum of a file and retry if the checksum mismatches? Add the FtpVerify options to UploadFile() or DownloadFile() to enable automatic checksum verification. // retry 3 times when uploading a file client.RetryAttempts = 3; // upload a file and retry 3 times before giving up client.UploadFile(@'C: MyVideo.mp4', '/htdocs/MyVideo.mp4', FtpExists.Overwrite, false, FtpVerify.Retry); All the possible configurations are: • FtpVerify.OnlyChecksum - Verify checksum, return true/false based on success.
• FtpVerify.Delete - Verify checksum, delete target file if mismatch. • FtpVerify.Retry - Verify checksum, retry copying X times and then give up.
• FtpVerify.Retry FtpVerify.Throw - Verify checksum, retry copying X times, then throw an error if still mismatching. • FtpVerify.Retry FtpVerify.Delete - Verify checksum, retry copying X times, then delete target file if still mismatching. • FtpVerify.Retry FtpVerify.Delete FtpVerify.Throw - Verify checksum, retry copying X times, delete target file if still mismatching, then throw an error How do I upload only the missing part of a file? Using the new UploadFile() API. Client.Encoding = System.Text.Encoding. GetEncoding( 1252); // ANSI codepage 1252 (Windows Western) Here is the full list of codepages based on the charset you need: • 874 – English + Thai • 1250 – English + Central Europe • 1251 – English + Cyrillic (Russian) • 1252 – English + European (accented characters) • 1253 – English + Greek • 1254 – English + Turkish • 1255 – English + Hebrew • 1256 – English + Arabic • 1257 – English + Baltic • 1258 – English + Vietnamese How does GetListing() work internally? • When you call GetListing(), FluentFTP first attempts to use machine listings (MLSD command) if they are supported by the server.
These are most accurate and you can expect correct file size and modification date (UTC). You may also force this mode using client.ListingParser = FtpParser.Machine, and disable it with the FtpListOption.ForceList flag. You should also include the FtpListOption.Modify flag for the most accurate modification dates (down to the second). • If machine listings are not supported we fallback to the appropriate OS-specific parser (LIST command), listed below. You may force usage of a specific parser using client.ListingParser = FtpParser.*. • Unix parser: Works for Pure-FTPd, ProFTPD, vsftpd, etc.
If you encounter errors you can always try the alternate Unix parser using client.ListingParser = FtpParser.UnixAlt. • Windows parser: Works for IIS, DOS, Azure, FileZilla Server, etc. • VMS parser: Works for Vax, VMS, OpenVMS, etc.
• NonStop parser: Works for Tandem, HP NonStop Guardian, etc. • IBM parser: Works for IBM OS/400, etc. • And if none of these satisfy you, you can fallback to name listings (NLST command), which are much slower than either LIST or MLSD.
This is because NLST only sends a list of filenames, without any properties. The server has to be queried for the file size, modification date, and type (file/folder) on a file-by-file basis. Name listings can be forced using the FtpListOption.ForceNameList flag.
What kind of hashing commands are supported? We support XCRC, XMD5, and XSHA which are non-standard commands and contain no kind of formal specification.
They are not guaranteed to work and you are strongly encouraged to check the FtpClient.Capabilities flags for the respective flag (XCRC, XMD5, XSHA1, XSHA256, XSHA512) before calling these methods. Support for the MD5 command as described has also been added. Again, check for FtpFeature.MD5 before executing the command. Support for the HASH command has been added to FluentFTP. It supports retrieving SHA-1, SHA-256, SHA-512, and MD5 hashes from servers that support this feature. The returned object, FtpHash, has a method to check the result against a given stream or local file. You can read more about HASH in.
How do I trace FTP commands for debugging? Do this at program startup (since its static it takes effect for all FtpClient instances.).NET Framework version. FtpTrace.LogFunctions = false; How do I omit sensitive information from the logs? Use these settings to control what data is included in the logs: • FtpTrace.LogUserName - Log FTP user names? • FtpTrace.LogPassword - Log FTP passwords? • FtpTrace.LogIP - Log FTP server IP addresses?
How do I use third-party logging frameworks like NLog? FluentFTP has a built-in named 'FluentFTP' that can be used for debugging and logging purposes. This is currently available for all.NET Framework versions except for.NET Standard. Any implementation of can be attached to the library either programmatically or via configuration in your app.config or web.config file. This will allow for direct logging or forwarding to third-party logging frameworks. Most tracing messages are of type Verbose or Information and can typically be ignored unless debugging.
Most ignored exceptions are classified as Warning, but methods that return boolean for success/failure will log the failure reasons with the Error level. If you are using.NET Standard and the DEBUG flag is set, then all logging messages will be issued via Debug.Write(message). Attaching TraceListener in code.
What does EnableThreadSafeDataConnections do? EnableThreadSafeDataConnections is an older feature built by the original author. If true, it opens a new FTP client instance (and reconnects to the server) every time you try to upload/download a file. It used to be the default setting, but it affects performance terribly so I disabled it and found many issues were solved as well as performance was restored. I believe if devs want multi-threaded uploading they should just start a new BackgroundWorker and create/use FtpClient within that thread.
Try that if you want concurrent uploading, it should work fine. How can I contribute some changes to FluentFTP? / How do I submit a pull request? First you must 'fork' FluentFTP, then make changes on your local version, then submit a 'pull request' to request me to merge your changes.
Client.SocketPollInterval = 1000; client.ConnectTimeout = 2000; client.ReadTimeout = 2000; client.DataConnectionConnectTimeout = 2000; client.DataConnectionReadTimeout = 2000; If none of these work, remember that Azure has in intermittent bug wherein it changes the IP-address during a FTP request. Acer Aspire 5750 Drivers For Windows Xp Sp2. The connection is established with IP-address A and for the data transfer Azure uses IP-address B and this isn't allowed on many firewalls. This is a known Azure bug. Many commands don't work on Windows CE According to from MSDN the Windows CE implementation of FTP is the bare minimum, and open to customization via source code. Many advanced commands such as CHMOD are unsupported. After successfully transfering a single file with OpenWrite/OpenAppend, the subsequent files fail with some random error, like 'Malformed PASV response' You need to call FtpReply status = GetReply() after you finish transfering a file to ensure no stale data is left over, which can mess up subsequent commands.
SSL Negotiation is very slow during FTPS login FluentFTP uses SslStream under the hood which is part of the.NET framework. SslStream uses a feature of windows for updating root CA's on the fly, which can cause a long delay in the certificate authentication process. This can cause issues in FluentFTP related to the SocketPollInterval property used for checking for ungraceful disconnections between the client and server. This covers the issue with SslStream and talks about how to disable the auto-updating of the root CA's. FluentFTP logs the time it takes to authenticate. If you think you are suffering from this problem then have a look at Examples Debug.cs for information on retrieving debug information. Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host This means that on the server the [FTP daemon] service isn't running (probably not the case) or the service is currently still busy performing another operation.
It almost sounds like the server is returning a message indicating it is still performing the last operation. Try reducing the polling interval to ensure that the connection does not time-out.
I am trying to write some VB code to delete files in an FTP directory. If I know the name of the file, I have no problems doing this. However, I would like to delete *any* file in the folder. My first thought (in the code below which DOES NOT WORK) was to use a wildcard. Anyone out there know of a way using FTPWebRequest to delete all files in a directory? In the example below, the part that doesn't work is Dim filename As String = ftpURI & '*.xml' If I replace the '*' with the name of a file I can see in the directory, then the rest of the code executes just fine.
Try Dim filename As String = ftpURI & '*.xml' Dim ftpReq As FtpWebRequest = WebRequest.Create(filename) ftpReq.Method = WebRequestMethods.Ftp.DeleteFile ftpReq.Credentials = New NetworkCredential('anonymous', 'password') Dim ftpResp As FtpWebResponse = ftpReq.GetResponse MsgBox(ftpResp.StatusDescription) Catch ex As Exception MsgBox(ex.ToString) End Try Select all. I'm guessing Shaun is most correct. And for anyone interested, this is how I came up with a way of doing this.
