Question

我正在使用引擎和asp.net客户端界面创建应用程序。目前我正在监控服务器是否可通过ping访问。在每个tick上，定时器调用一些类并为_evmComputerEntries中的每个服务器执行IsAlive（ping）

我有一个计时器（测试和故障排除的间隔为5秒）

Timer timer = new Timer(5000);
timer.Elapsed += new ElapsedEventHandler(timer_Elapsed);
timer.Enabled = true;

public void timer_Elapsed(object sender, ElapsedEventArgs e)
    {
        _BLComputerStatus.Open();
        foreach (evmComputerEntry evmComputerEntry in _evmComputerEntries)
        {
            //eventLogEVMON.WriteEntry(DateTime.Now.ToString());
            evmComputerStatus evmComputerStatus;
            if (IsAlive(evmComputerEntry.ComputerName))
            {
                evmComputerStatus = new evmComputerStatus(0, evmComputerEntry.ComputerEntryId, 1, DateTime.Now);
            }
            else
            {
                evmComputerStatus = new evmComputerStatus(0, evmComputerEntry.ComputerEntryId, 0, DateTime.Now);
            }
            _BLComputerStatus.InsertComputerStatusEntry(evmComputerStatus);
        }
        _BLComputerStatus.Close();
    }

Becaus我调用Open和Close函数来打开和关闭SQL连接，我认为不应该有问题吗？

这是IsAlive功能：

public bool IsAlive(string server)
    {
        bool result = false;
        try
        {
            Ping pingSender = new Ping();
            PingOptions options = new PingOptions();
            options.DontFragment = true;
            string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
            byte[] buffer = Encoding.ASCII.GetBytes(data);
            int timeout = 120;
            PingReply reply = pingSender.Send(server, timeout, buffer, options);
            if (reply.Status == IPStatus.Success)
                result = true;
        }
        catch
        {
            result = false;
        }
        return result;
    }

evmComputerStatus：

    private int computerStatusId, status;
    private string computerEntryId;
    private DateTime statusTime;

    public evmComputerStatus(int ComputerStatusId, string ComputerEntryId, int Status, DateTime StatusTime)
    {
        this.computerStatusId = ComputerStatusId;
        this.computerEntryId = ComputerEntryId;
        this.status = Status;
        this.statusTime = StatusTime;
    }

你应该处理Ping

public bool IsAlive(string server)
    {
        bool result = false;
        try
        {
            using (Ping pingSender = new Ping()) {
                PingOptions options = new PingOptions();
                options.DontFragment = true;
                string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
                byte[] buffer = Encoding.ASCII.GetBytes(data);
                int timeout = 120;
                PingReply reply = pingSender.Send(server, timeout, buffer, options);
                if (reply.Status == IPStatus.Success)
                    result = true;
            }
        }
        catch
        {
            result = false;
        }
        return result;
    }
