Question

我正在编写一个小工具来检查c＃wpf中服务器的ping延迟。我使用Windows Forms做了类似的事情，发生的问题似乎是一样的。过了一段时间，我得到一个蓝屏，包括内存转储。问题是由ntoskrnl.exe引起的，我不明白为什么。我所做的就是每1000毫秒ping一些服务器。

这是我的c＃代码：

using System.Text;

using System.ComponentModel;

    ObservableCollection<PingTarget> PingTargets = new ObservableCollection<PingTarget>();
    PingTargetHost pth = new PingTargetHost();
    public MainWindow()
    {
        pth.PingTargetList = new ObservableCollection<PingTarget>();
        InitializeComponent();
        PingTarget ptExample = new PingTarget { TargetName = "Google", TargetIP = "www.google.ch" };
        pth.PingTargetList.Add(ptExample);

        PingTargetListBox.ItemsSource = pth.PingTargetList;
    }

    private void AddNewTarget_Click(object sender, RoutedEventArgs e)
    {
        PingTarget newTarget = new PingTarget { TargetName = NewTargetNametb.Text, TargetIP = NewTargetIPtb.Text };

    }

    public long MaxPing
    {

            return PingCollection.Max(p => p.Value);
        }
    }

    public long MinPing

        {
            Ping pingSender = new Ping();
            string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
            int timeout = 10000;

    private DispatcherTimer Ticker { get; set; }

    public ObservableCollection<PingTarget> PingTargetList { get; set; }

有什么想法吗？我真的很喜欢这个没有蓝屏的工具;）

非常感谢你的帮助！
