Question

我想连接到Dell X1008交换机并运行一些命令。我使用过C＃Tamir.SharpSsh和Renci.SshNet库。

Using Tamir.SharpSsh;

SshExec exec = new SshExec("ip address", "username", "password");
exec.Connect();
var output = exec.RunCommand("show vlan");
exec.Close();

但我的代码冻结了＆＃34; exec.RunCommand（＆＃34; show vlan＆＃34;）＆＃34;线。

 using Renci.SshNet;
 using (var client = new SshClient(Host, UserName, Password))
        {
            try
            {
                client.Connect();
            }
            catch (Exception ex)
            {

                throw;
            }

            var command = client.CreateCommand("show vlan");
            return command.Execute();
        }

这里我的代码冻结了＆＃34; var command = client.CreateCommand（cmd）＆＃34;线。

任何人都可以了解它吗？

仅供参考：以上代码适用于思科交换机。我可以通过Putty软件连接到戴尔和思科交换机，我可以运行来自putty的命令。我的要求是从C＃应用程序运行命令。

此致

Renci.SshNet是更好的选择。

检查此方法的响应，该命令有超时。

public string ExecuteCommandSsh(string host, int port, string username, string password, string[] commands)
{
    var returnMessage = string.Empty;

    try
    {
        using (var client = new SshClient(host, port, username, password))
        {
            //Create the command string
            var fullCommand = string.Empty;
            foreach (var command in commands)
            {
                fullCommand += command + "\n";
            }

            client.Connect();
            var sshCommand = client.CreateCommand(fullCommand);
            sshCommand.CommandTimeout = new TimeSpan(0, 0, 10);

            try
            {
                sshCommand.Execute();
                returnMessage = sshCommand.Result;
            }
            catch (SshOperationTimeoutException)
            {
                returnMessage = sshCommand.Result;
            }


            client.Disconnect();
        }
    }
    catch (Exception e)
    {
        //other exception
    }

    return returnMessage;
}
