How do I upload a file to an SFTP server in C# (.NET)? [closed]

Question

Does a free .NET library exist with which I can upload a file to a SFTP (SSH FTP) server, which throws exceptions on problems with the upload and allows the monitoring of its progress?

Answer 1

Maybe you can script/control winscp?

Update: winscp now has a .NET library available as a nuget package that supports SFTP, SCP, and FTPS

Answer 2

Following code shows how to upload a file to a SFTP server using our Rebex SFTP component.

// create client, connect and log in  Sftp client = new Sftp(); client.Connect(hostname); client.Login(username, password);  // upload the 'test.zip' file to the current directory at the server  client.PutFile(@"c:\data\test.zip", "test.zip");  client.Disconnect(); 

You can write a complete communication log to a file using a LogWriter property as follows. Examples output (from FTP component but the SFTP output is similar) can be found here.

client.LogWriter = new Rebex.FileLogWriter(    @"c:\temp\log.txt", Rebex.LogLevel.Debug);  

or intercept the communication using events as follows:

Sftp client = new Sftp(); client.CommandSent += new SftpCommandSentEventHandler(client_CommandSent); client.ResponseRead += new SftpResponseReadEventHandler(client_ResponseRead); client.Connect("sftp.example.org");  //...  private void client_CommandSent(object sender, SftpCommandSentEventArgs e) {     Console.WriteLine("Command: {0}", e.Command); }  private void client_ResponseRead(object sender, SftpResponseReadEventArgs e) {     Console.WriteLine("Response: {0}", e.Response); }
