Question

当我在使用Visual Studio（尝试通过ssh运行命令）时出现问题，程序无效。我在网上搜索了几个小时，但没有找到任何解决我问题的方法。

这是代码：

using Renci.SshNet;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WindowsFormsApplication3
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            using (var sshClient = new SshClient("ip censor", "root", "password censor"))
            {
                sshClient.Connect();
                sshClient.RunCommand("screen -S BungeeCord -X stuff 'alert ciao'`echo -ne '\015'`");
                sshClient.Disconnect();
            }
        }
    }
}

这是错误

我在做错了什么？谢谢你的帮助！

它正在工作，你没有对输出做任何事情。尝试在消息框中显示输出，如下所示：

private void button1_Click(object sender, EventArgs e)
{
    using (var sshClient = new SshClient("ip censor", "root", "password censor"))
    {
        sshClient.Connect();
        var cmd = sshClient.RunCommand("screen -S BungeeCord -X stuff 'alert ciao'`echo -ne '\015'`");

        MessageBox.Show(cmd.Output);

        sshClient.Disconnect();
    }
}

正如redspidermkv的答案所述，代码是正确的，但输出没有任何用处。通常这没关系，您可以定义一个变量但不使用它，或者例如关闭命令等，以防它是连接，您可以尝试以下方法：

建立联系：

public class SSHConnection
    {
        public SSHConnection() { }
    public ConnectionInfo makeSSHConnection(string ipAdress, int port, string user, string pwd)
    {
        ConnectionInfo ConnNfo = new ConnectionInfo(ipAdress, port, user,
          new AuthenticationMethod[]{

            // Pasword based Authentication
            new PasswordAuthenticationMethod(user,pwd),
          }
             );
        return ConnNfo;
    }
}

使用ConnNfo进行连接;

using (var sshclient = new SshClient(ConnNfo))
                {

                    sshclient.Connect();
                    using (var cmd = sshclient.CreateCommand(cmdCommand))
                    {

                        cmd.Execute();
                        Console.WriteLine("Command>" + cmd.CommandText);
                        Console.WriteLine(cmd.Result);
                        Console.WriteLine("Return Value = {0}", cmd.ExitStatus);
                    }
                    sshclient.Disconnect();
                }

请注意，此示例使用ssh连接执行cmd comamndline函数，但您可以使用ssh命令轻松替换它。

（你确定是ssh代码会出错吗？）

ssh.net没有连接到ssh服务器
