C＃連接並運行命令到Dell交換機

Question

我想連接到Dell X1008交換機並運行一些命令。我使用了C＃Tamir.SharpSsh和Renci.SshNet庫。

Using Tamir.SharpSsh; 

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

但我的代碼凍結在「exec.RunCommand（」show vlan「）」行。

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(); 
     } 

這裏我的代碼凍結在「var command = client.CreateCommand（cmd）」行。

任何人都有想法嗎？以上代碼適用於Cisco交換機。我可以通過Putty軟件連接到Dell和Cisco交換機，並且可以從putty運行命令。我的要求是從C＃應用程序運行命令。

Renci.SshNet是更好的選擇。

檢查此方法的響應，該命令有超時。

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; 
}
