.NET Get the current connection

2022-09-22 04:30

After I open a connection with the .NET/WinSCP-Lib I will see, the current connection info. How can I do it to see, which protocol, if TLS is used and so on.

When you open a session with the WinSCP .NET assembly, you know what protocol did you ask it to use, don't you?

Yes - but i will know if my session is correct set.

Look, my code is:

With FTPCon
    .Protocol = Protocol.Ftp
    .HostName = FtpServer.ServerAdress
    .UserName = FtpServer.UserName
    .Password = FtpServer.Password
    .PortNumber = FtpServer.Port
    .FtpSecure = FtpSecure.Explicit
    .GiveUpSecurityAndAcceptAnyTlsHostCertificate = True
End With

But I will know, if TLS1.3 is used.

Finding out what version of TLC is used is very different problem than what you have asked originally. You can find that in the session log only.
But instead, you can make WinSCP not allow older versions of TLS:

FTPCon.AddRawSettings("MinTlsVersion", "13")

But if you want a secure connection, you cannot set GiveUpSecurityAndAcceptAnyTlsHostCertificate = True in the first place!
