.net 如何连接linux上传下载文件？

1.net连接linux上传下载文件可以通过scp命令来实现，首先需要我们引入“Renci.SshNet.dll”

  public class SCPOperation
    {
        private ScpClient ssh;

        /// <summary>
        /// SCP连接状态
        /// </summary>
        public bool Connected { get { return ssh.IsConnected; } }

        /// <summary>
        /// 构造方法
        /// </summary>
        /// <param name="ip">IP</param>
        /// <param name="port">端口</param>
        /// <param name="user">用户名</param>
        /// <param name="pwd">密码</param>
        public SCPOperation(string ip, string port, string user, string pwd)
        {
            ssh = new ScpClient(ip, Int32.Parse(port), user, pwd);
        }

        /// <summary>
        /// 连接SCP
        /// </summary>
        /// <returns>true成功</returns>
        public bool Connect()
        {
            try
            {
                if (!Connected)
                {
                    ssh.Connect();
                }
                return true;
            }
            catch (Exception ex)
            {
                throw new Exception(string.Format("连接SFTP失败，原因：{0}", ex.Message));
            }
        }

        /// <summary>
        /// 断开SCP
        /// </summary> 
        public bool Disconnect()
        {
            try
            {
                if (ssh != null && Connected)
                {
                    ssh.Disconnect();
                }
                return true;
            }
            catch (Exception ex)
            {
                throw new Exception(string.Format("断开SFTP失败，原因：{0}", ex.Message));
            }
        }

        /// <summary>
        /// SCP上传文件
        /// </summary>
        /// <param name="localPath">本地路径</param>
        /// <param name="remotePath">远程路径</param>
        public int Upload(string localPath, string remotePath)
        {
            try
            {
                FileInfo file = new FileInfo(localPath);
                Connect();
                ssh.Upload(file, remotePath);
                Disconnect();
                return 1;
            }
            catch (Exception ex)
            {
                throw new Exception(string.Format("SFTP文件上传失败，原因：{0}", ex.Message));
                return 0;
            }
        }

        /// <summary>
        /// SCP获取文件
        /// </summary>
        /// <param name="remotePath">远程路径</param>
        /// <param name="localPath">本地路径</param>
        public void Get(string remotePath, string localPath)
        {
            try
            {
                Connect();
                DirectoryInfo localdir = new DirectoryInfo(localPath);
                ssh.Download(remotePath, localdir);
                Disconnect();
            }
            catch (Exception ex)
            {
                throw new Exception(string.Format("SFTP文件获取失败，原因：{0}", ex.Message));
            }

        }

    }

2.调用测试：

 　　　　　　 string host = "192.168.1.1";
            string user = "root";
            string pwd = "koolshare";
            string port = "22";
            string remotePath = "/tmp/";
            string localPath = @"d:/test.txt";
            SCPOperation scpClinet = new SCPOperation(host, port, user, pwd);
            bool isSuccess = scpClinet.Connect();
            if (isSuccess)
            {
                Console.WriteLine("connect success");
                scpClinet.Put(localPath, remotePath);
            }
            else
            {
                Console.WriteLine("failed");
            }
