Question

我使用Renci.SshNet通过ssh连接到服务器。

using (var client = new SshClient("server.com", "", ""))
        {
            client.Connect();

            var cmd = client.CreateCommand("do soemthing");
            var result = cmd.Execute();

            statusWindow.Items.Add(result);

            var reader = new StreamReader(cmd.ExtendedOutputStream);

            using (StringReader readerIt = new StringReader(reader.ReadToEnd()))
            {
                string line;
                while ((line = readerIt.ReadLine()) != null)
                {
                    statusWindow.Items.Add(line);
                }
            }

            client.Disconnect();

        }

它工作正常，但在尝试将此代码添加到后台工作程序时，我收到以下错误;

类型＆＃39; System.Net.Sockets.SocketException＆＃39;的例外情况发生在System.dll中但未在用户代码中处理

附加信息：引用的对象类型
不支持尝试的操作

这是后台工作人员代码;

public void connectBtn_Click(object sender, EventArgs e)
    {

        BackgroundWorker worker = new BackgroundWorker();
        worker.DoWork += new DoWorkEventHandler(worker_DoWork);
        worker.ProgressChanged += new ProgressChangedEventHandler(worker_Changed);
        worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(worker_RunWorkerCompleted);
        worker.RunWorkerAsync();
    }

    public void worker_DoWork(object sender, DoWorkEventArgs e)
    {

        using (var client = new SshClient("server.com", "", ""))
        {
            client.Connect();

            var cmd = client.CreateCommand("do soemthing");
            var result = cmd.Execute();

            statusWindow.Items.Add(result);

            var reader = new StreamReader(cmd.ExtendedOutputStream);

            using (StringReader readerIt = new StringReader(reader.ReadToEnd()))
            {
                string line;
                while ((line = readerIt.ReadLine()) != null)
                {
                    statusWindow.Items.Add(line);
                }
            }

            client.Disconnect();

        }

    }

它在client.Connect（）;

上引发了异常

为什么会出现这种情况有一个简单的原因？

编辑：我完全不知道为何会出现这种情况，我们将非常感谢任何帮助！
