I'm using sshnet for the first time and have a question. I use the following code to connect

using (var client = new SshClient("<site>", port, "<uid>", "<pw>"))

When I invoke the runcommand method, I receive a message that "client is not connected". When I check the client.IsConnected and client.IsAuthenticated attribute, both come back as true. Can someone point me in the right direction? All I'm trying to do is download and upload several files.

Thank you.

I'm not able to reproduce this issue.
Please post the complete stacktrace.

What SSH server are you using, and which version of SSH.NET ?

The SSH server I am trying to invoke is
"SSH-2.0-IBM Sterling Connect:Enterprise for UNIX2.5.00"

I seem to be able to connect but cannot invoke commands.

What version of SSH.NET are you using ?
Can you verify whether SshClient.IsConnect is still true after the exception ?

Also try subscribing to the Exception event to learn more on the reason why the connection was dropped:
            using (var client = new SftpClient(...))
                client.ErrorOccurred += (sender, args) => Console.WriteLine(args.Exception);

if found out that really don't apply to a ssh session
using (var client = new SshClient(comboBox1.Text, username.Text, password.Text))
                if (client.IsConnected)
                    client.RunCommand("system reboot");
but it says connected and run the command
