c# 连接操作linux

0.背景

现在linux重要性是显然易见的，学习linux是必须，通过程序来来控制linux 也能发挥很大的作用。比如我们可以做一个自动化部署的程序，来发布程序到linux上面。

1.在项目中添加SSH.NET 

2.如何使用SSH.NET 直接上来代码

 private static string host = "xxx.xxx.xxx.xx";
        private static string username = "root";
        private static string password = "pwd";

        // Setup Credentials and Server Information
        public static ConnectionInfo ConnNfo = new ConnectionInfo(host, 22, username,
             new AuthenticationMethod[]{
                // Pasword based Authentication
                new PasswordAuthenticationMethod(username,password),
                 // Key Based Authentication (using keys in OpenSSH Format)
                 //new PrivateKeyAuthenticationMethod("username",new PrivateKeyFile[]{
                 //    new PrivateKeyFile(@"..openssh.key","passphrase")
                 //}),
             }
         );

        static void Main(string[] args)
        {

            ExecuteCommand1();
            ExecuteCommand2();
            Upload();
            Console.ReadLine();
        }

        /// <summary>
        /// 开始
        /// </summary>

            {
                try
                {
                    string command = "ls";
                    client.Connect();
                    string result = client.RunCommand(command).Execute();
                    Console.WriteLine(result);
                    client.Disconnect();
                }
                catch (Exception e1)

                sshclient.Connect();
                using (var cmd = sshclient.CreateCommand("cd /local && ls"))
