连接到多个设备

Question

我有 14 台不同的设备需要同时建立连接，每隔几分钟重新检查连接状态。

我想知道是否需要为每个人创建一个线程，或者是否有更好的方法。

public partial class Automation : Form
{
        public Automation()
        {
            InitializeComponent();
        }
        //======================================================================
        TelnetConnection Telnet1 = new TelnetConnection("10.10.100.21", 9090);
        TelnetConnection Telnet2 = new TelnetConnection("10.10.100.22", 9090);
        TelnetConnection Telnet3 = new TelnetConnection("10.10.100.23", 9090);
        TelnetConnection Telnet4 = new TelnetConnection("10.10.100.24", 9090);
        TelnetConnection Telnet5 = new TelnetConnection("10.10.100.25", 9090);
        TelnetConnection Telnet6 = new TelnetConnection("10.10.100.26", 9090);
        TelnetConnection Telnet7 = new TelnetConnection("10.10.100.27", 9090);
        //======================================================================
        TelnetConnection ADV1 = new TelnetConnection("10.10.100.1", 9090);
        TelnetConnection ADV2 = new TelnetConnection("10.10.100.2", 9090);
        TelnetConnection ADV3 = new TelnetConnection("10.10.100.3", 9090);
        TelnetConnection ADV4 = new TelnetConnection("10.10.100.4", 9090);
        TelnetConnection ADV5 = new TelnetConnection("10.10.100.5", 9090);
        TelnetConnection ADV6 = new TelnetConnection("10.10.100.6", 9090);
        TelnetConnection ADV7 = new TelnetConnection("10.10.100.7", 9090);
        //======================================================================
        private void Automation_Load(object sender, EventArgs e)
        {
            //===========Check Online State===========//
            Check_Online_Offline_State();
            //===========Check Online State===========//
        }
}

我还会在需要时发送每个设备命令 但问题出在 telnet 连接上，因为它们在 3 次连接后遇到异常，但如果我只运行 advs，它就可以建立连接。

建议？

使用Parallel.ForEach，它是异步多线程，代码少，只是示例：

  private TelnetConnection[] m_Connections;
  ...
  m_Connections = new TelnetConnection[50];
  for (var i = 0; i < m_Connections.Length; i++)
  {
    m_Connections[i] = new TelnetConnection(string.Concat("10.10.100.", i), 9090);
  }
  ...
  Parallel.ForEach(m_Connections, conn =>
  {
    bool isAlive = conn.IsHostAlive();
  });
