.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”

  1   public class SCPOperation
  2     {
  3         private ScpClient ssh;
  4 
  5         /// <summary>
  6         /// SCP连接状态
  7         /// </summary>
  8         public bool Connected { get { return ssh.IsConnected; } }
  9 
 10         /// <summary>
 11         /// 构造方法
 12         /// </summary>
 13         /// <param name="ip">IP</param>
 14         /// <param name="port">端口</param>
 15         /// <param name="user">用户名</param>
 16         /// <param name="pwd">密码</param>
 17         public SCPOperation(string ip, string port, string user, string pwd)
 18         {
 19             ssh = new ScpClient(ip, Int32.Parse(port), user, pwd);
 20         }
 21 
 22         /// <summary>
 23         /// 连接SCP
 24         /// </summary>
 25         /// <returns>true成功</returns>
 26         public bool Connect()
 27         {
 28             try
 29             {
 30                 if (!Connected)
 31                 {
 32                     ssh.Connect();
 33                 }
 34                 return true;
 35             }
 36             catch (Exception ex)
 37             {
 38                 throw new Exception(string.Format("连接SFTP失败，原因：{0}", ex.Message));
 39             }
 40         }
 41 
 42         /// <summary>
 43         /// 断开SCP
 44         /// </summary> 
 45         public bool Disconnect()
 46         {
 47             try
 48             {
 49                 if (ssh != null && Connected)
 50                 {
 51                     ssh.Disconnect();
 52                 }
 53                 return true;
 54             }
 55             catch (Exception ex)
 56             {
 57                 throw new Exception(string.Format("断开SFTP失败，原因：{0}", ex.Message));
 58             }
 59         }
 60 
 61         /// <summary>
 62         /// SCP上传文件
 63         /// </summary>
 64         /// <param name="localPath">本地路径</param>
 65         /// <param name="remotePath">远程路径</param>
 66         public int Upload(string localPath, string remotePath)
 67         {
 68             try
 69             {
 70                 FileInfo file = new FileInfo(localPath);
 71                 Connect();
 72                 ssh.Upload(file, remotePath);
 73                 Disconnect();
 74                 return 1;
 75             }
 76             catch (Exception ex)
 77             {
 78                 throw new Exception(string.Format("SFTP文件上传失败，原因：{0}", ex.Message));
 79                 return 0;
 80             }
 81         }
 82 
 83         /// <summary>
 84         /// SCP获取文件
 85         /// </summary>
 86         /// <param name="remotePath">远程路径</param>
 87         /// <param name="localPath">本地路径</param>
 88         public void Get(string remotePath, string localPath)
 89         {
 90             try
 91             {
 92                 Connect();
 93                 DirectoryInfo localdir = new DirectoryInfo(localPath);
 94                 ssh.Download(remotePath, localdir);
 95                 Disconnect();
 96             }
 97             catch (Exception ex)
 98             {
 99                 throw new Exception(string.Format("SFTP文件获取失败，原因：{0}", ex.Message));
100             }
101 
102         }
103 
104     }

2.调用测试：

 1  　　　　　　 string host = "192.168.1.1";
 2             string user = "root";
 3             string pwd = "koolshare";
 4             string port = "22";
 5             string remotePath = "/tmp/";
 6             string localPath = @"d:/test.txt";
 7             SCPOperation scpClinet = new SCPOperation(host, port, user, pwd);
 8             bool isSuccess = scpClinet.Connect();
 9             if (isSuccess)
10             {
11                 Console.WriteLine("connect success");
12                 scpClinet.Put(localPath, remotePath);
13             }
14             else
15             {
16                 Console.WriteLine("failed");
17             }
