使用WinSCP .NET程序集通过FTPS（安全）发送文件

Question

What is required to send out files to a server with WinSCP (.NET assembly) using FTPS (Secure)?

I've been looking at their documentation and am not really clear on certain aspects like TlsHostCertificateFingerprint or TlsClientCertificatePath .

I've been able to send out files via FTP and SFTP with no problem, but this whole thing just eludes me.

If you have a code for FTP, all you need to add to connect to a well-behaved FTPS (FTP over TLS/SSL) server is to set the SessionOptions.FtpSecure :

// Set up session options
SessionOptions sessionOptions = new SessionOptions
{
    Protocol = Protocol.Ftp,
    HostName = "ftp.example.com",
    UserName = "username",
    Password = "password",
    // Enable FTPS in explicit mode, aka FTPES
    FtpSecure = FtpSecure.Explicit,
};

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

    // Your code
}

The TlsHostCertificateFingerprint is needed only, if your server certificate is not signed by a trusted authority.

The TlsClientCertificatePath is needed only, if your server requires authenticating with a client certificate.

Easiest is to configure your session in WinSCP GUI and have it generate a code template for you. That's actually how I got the above code.
