如何从c＃

Question

这是我在stackoverflow上的第一篇文章，对不起任何事情。

关于我的范围：

private SshClient client;
private ForwardedPortDynamic port;

我有一个示例代码，用于连接类似于putty的ssh：

private void Connect()
    {
        try
        {
            client = new SshClient("myserverproxy.net", "user", "password");
            client.KeepAliveInterval = new TimeSpan(0, 0, 60);
            client.ConnectionInfo.Timeout = new TimeSpan(0, 0, 20);
            client.Connect();
            port = new ForwardedPortDynamic("127.0.0.1", 20141);
            client.AddForwardedPort(port);
            port.Exception += delegate(object sender, ExceptionEventArgs e)
            {
                Console.WriteLine(e.Exception.ToString());
            };
            port.Start();
        }
        catch (Exception)
        {
            throw;
        }
    }

此代码断开连接：

private void Disconnect()
    {
        try
        {
            port.Stop();
            client.Disconnect();
        }
        catch (Exception)
        {

            throw;
        }
    }

我有一个按钮来调用方法“Connect（）”，但一段时间后它断开连接并且不再工作。导致断开的原因是什么？我需要建立连接不确定的时间。

非常感谢！

首先SshClient是一次性的，因此需要使用using关键字进行调用。像这样：

using (client = new SshClient("myserverproxy.net", "user", "password")) {
    client.KeepAliveInterval = new TimeSpan(0, 0, 60);
    client.ConnectionInfo.Timeout = new TimeSpan(0, 0, 20);
    client.Connect();
    port = new ForwardedPortDynamic("127.0.0.1", 20141);
    ...
}

其次，您阅读this建议您需要使用ForwardedPortLocal代替ForwardedPortDynamic。

我无法尝试，但我会这样做：

public static void Start()
{
      using (var client = new SshClient("myserverproxy.net", "user", "password"))
      {
           client.KeepAliveInterval = new TimeSpan(0, 0, 60);
           client.ConnectionInfo.Timeout = new TimeSpan(0, 0, 20);
           client.Connect();
           ForwardedPortDynamic port = new ForwardedPortDynamic("127.0.0.1", 20141);
           client.AddForwardedPort(port);
           port.Exception += delegate(object sender, ExceptionEventArgs e)
           {
                Console.WriteLine(e.Exception.ToString());
           };
           port.Start();
     }
}

public static void Main(string[] args)
{
     Thread thread1 = new Thread(Start);
     thread1.Start();
}

将KeepAliveInterval设置为30s可能会有帮助吗？
