C# sshClient 执行runcommand 无反应

C# sshClient 必须先登陆一层，才能进入下一层，进入abc用户后，执行runcommand后无反应

 private static void GetSshClient()
        {
            string conntCommand = "su - abc";
            string conntPasdCommand = "abc";
            string remoteFirstCommand = "cd xxx/xx/";
            string remoteSecordCommand = "cd ~";
            string remoteThirdCommand = "cd /xxx/xxx/";
            string CopyCommand = "cp -rp test.dat /xx/xx/";
            string DeleteCommand = "rm test.dat";
            List<FileInfo> lstEffectedFile = new List<FileInfo>();
            SshClient sshClient = GetSSHClient();
            try
            {
                sshClient.Connect();
                if (sshClient.IsConnected)
                {
                    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(sTSName, 80, 24, 800, 600, 1024);
                    string rep = shellStream.Expect(new Regex(@"[$>]")); //Get logged in expect user prompt
                    sshClient.RunCommand(conntCommand);
                    if (rep.Contains(":"))//check to send password
                    {
                        shellStream.WriteLine(conntPasdCommand);//send password
                        rep = shellStream.Expect(new Regex(@"[$#>]")); //expect user,root or other prompt
                        sshClient.CreateCommand(remoteFirstCommand);
                        sshClient.RunCommand(remoteSecordCommand);
                        sshClient.RunCommand(remoteThirdCommand);
                        sshClient.RunCommand(CopyCommand);
                        sshClient.RunCommand(DeleteCommand);
                        GetDatFiles();
                    }
                    sshClient.Disconnect();
                    sshClient.Dispose();
                }
                else
                {
                    RecordLog("Lost connection with server.");
                }
            }
            catch (Exception ex)
            {
                RecordLog("Parsing error!!");
            }
        }

在你的代码中，有几个地方需要进行优化和修改以使RunCommand方法正常运行。

首先，你需要使用CreateCommand方法创建一个命令对象，并保存为一个变量。然后，你需要将这个命令对象传递给RunCommand方法。

其次，你需要使用Execute方法执行命令，并获取命令的输出结果。你可以使用StandardOutput属性获取命令输出的结果。

下面是修改后的代码示例：

private static void GetSshClient()
{
    string conntCommand = "su - abc";
    string conntPasdCommand = "abc";
    string remoteFirstCommand = "cd xxx/xx/";
    string remoteSecordCommand = "cd ~";
    string remoteThirdCommand = "cd /xxx/xxx/";
    string CopyCommand = "cp -rp test.dat /xx/xx/";
    string DeleteCommand = "rm test.dat";
    List<FileInfo> lstEffectedFile = new List<FileInfo>();
    SshClient sshClient = GetSSHClient();
    try
    {
        sshClient.Connect();
        if (sshClient.IsConnected)
        {
            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(sTSName, 80, 24, 800, 600, 1024);
            string rep = shellStream.Expect(new Regex(@"[$>]")); //Get logged in expect user prompt
            sshClient.RunCommand(conntCommand);

            if (rep.Contains(":")) //check to send password
            {
                shellStream.WriteLine(conntPasdCommand); //send password
                rep = shellStream.Expect(new Regex(@"[$#>]")); //expect user,root or other prompt
                var command = sshClient.CreateCommand(remoteFirstCommand);
                command.Execute();
                var result1 = command.Result;

                command = sshClient.CreateCommand(remoteSecordCommand);
                command.Execute();
                var result2 = command.Result;

                command = sshClient.CreateCommand(remoteThirdCommand);
                command.Execute();
                var result3 = command.Result;

                command = sshClient.CreateCommand(CopyCommand);
                command.Execute();
                var result4 = command.Result;

此处，我添加了对命令执行的结果进行保存并获取的代码，并将创建的命令对象传递给RunCommand方法进行执行。

这样就可以更好地优化你的代码，并使RunCommand方法正常运行。

单独在ssh客户端里运行，和C#的命令对比
