c# - C# SSH .Net 库中的 Sudo 命令

Question

这是我能找到的 SSH .Net 库的最简单的 sudo 实现。但是，我无法让它工作。

    using (var ssh = new SshClient("hostname", "username", "password"))
        {
            ssh.Connect();
            var input = new MemoryStream();
            var sr = new StreamWriter(input);
            var output = Console.OpenStandardOutput();

            var shell = ssh.CreateShell(input, output, output);
            shell.Stopped += delegate
            {
                Console.WriteLine("\nDisconnected...");
            };

            shell.Start();
            sr.WriteLine("sudo ls");
            sr.Flush();
            Thread.Sleep(1000 * 1);
            sr.WriteLine("password");
            sr.Flush();
            Thread.Sleep(1000 * 100);
            shell.Stop();
        }

我每次都会收到以下错误

        public void ExpectSSH (string address, string login, string password, string command)
    {
        try
        {
            SshClient sshClient = new SshClient(address, 22, login, password);

            sshClient.Connect();
            IDictionary<Renci.SshNet.Common.TerminalModes, uint> termkvp = new Dictionary<Renci.SshNet.Common.TerminalModes, uint>();
            termkvp.Add(Renci.SshNet.Common.TerminalModes.ECHO, 53);

            ShellStream shellStream = sshClient.CreateShellStream("xterm", 80,24, 800, 600, 1024, termkvp);


            //Get logged in
            string rep = shellStream.Expect(new Regex(@"[$>]")); //expect user prompt
            this.writeOutput(results, rep);

            //send command
            shellStream.WriteLine(commandTxt.Text);
            rep = shellStream.Expect(new Regex(@"([$#>:])")); //expect password or user prompt
            this.writeOutput(results, rep);

            //check to send password
            if (rep.Contains(":"))
            {
                //send password
                shellStream.WriteLine(password);
                rep = shellStream.Expect(new Regex(@"[$#>]")); //expect user or root prompt
                this.writeOutput(results, rep);
            }

            sshClient.Disconnect();      
        }//try to open connection
        catch (Exception ex)
        {
            System.Console.WriteLine(ex.ToString());
            throw ex;
        }

    }
