SFTP with .NET 3.5

Question

I need to connect to an SFTP server to download and upload files using C # /. NET 3.5.

Does the .NET 3.5 environment provide any built-in tools / mechanisms / libraries for connecting to the SFTP server for downloading and uploading files?

Answer 1

There are commercial solutions:

• http://www.rebex.net/sftp.net/
• http://www.enterprisedt.com/products/edtftpnetpro/overview.html

... and for free:

• http://www.tamirgal.com/blog/page/SharpSSH.aspx Strike>

I personally have no experience with any of them.

Answer 2

There is no SFTP support in the .NET framework in any version.

# SFTP:

// Setup session options
SessionOptions sessionOptions = new SessionOptions
{
    Protocol = Protocol.Sftp,
    HostName = "example.com",
    UserName = "user",
    Password = "mypassword",
    SshHostKeyFingerprint = "ssh-rsa 2048 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx"
};

using (Session session = new Session())
{
    // Connect
    session.Open(sessionOptions);

    // Upload files
    session.PutFiles(@"d:\toupload\*", "/home/user/").Check();
}

VB.NET:

' Setup session options
Dim sessionOptions As New SessionOptions
With sessionOptions
    .Protocol = Protocol.Sftp
    .HostName = "example.com"
    .UserName = "user"
    .Password = "mypassword"
    .SshHostKeyFingerprint = "ssh-rsa 2048 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx"
End With

Using session As New Session
    ' Connect
    session.Open(sessionOptions)

    ' Upload files
    session.PutFiles("d:\toupload\*", "/home/user/").Check()
End Using

Since there is no built-in support, you can search on Google for other, commercial, components, just enter something like “.NET SFTP Components”
