class MainProgram { static NotifyIcon _notifyIcon; public static void Main() { _notifyIcon = new NotifyIcon(); _notifyIcon.Icon = new Icon("icon.ico"); _notifyIcon.Click += NotifyIconInteracted; _notifyIcon.Visible = true; while(true) { Thread.Sleep(1000); } } static void NotifyIconInteracted(object sender, EventArgs e) { throw new NotImplementedException(); } } 以上是一个最小的例子。 由于某种原因，NotifyIconInteracted方法从不被调用。 通知图标显示，我多次离开/右键点击它，事件不会触发。
如果只是定期检查，为什么不使用定时器而不是while循环？ 使用定时器不会像while（）循环那样锁定程序。
using System; using System.Timers; using System.Windows.Forms; namespace SONotify { class Program { private static System.Timers.Timer _timer; private static NotifyIcon _notify; static void Main(string[] args) { Console.WriteLine("Press enter to exit"); SetIcon(); SetTimer(); Application.Run(); Console.ReadLine(); _timer.Stop(); _timer.Dispose(); } private static void SetIcon() { _notify = new NotifyIcon(); _notify.Icon = new System.Drawing.Icon("icon.ico"); _notify.Click += NotifyIconInteracted; _notify.Visible = true; } private static void SetTimer() { _timer = new System.Timers.Timer(2000); //Timer goes off every 2 seconds _timer.Elapsed += Timer_Elapsed; _timer.AutoReset = true; _timer.Enabled = true; } private static void Timer_Elapsed(object sender, ElapsedEventArgs e) { Console.WriteLine("Timer fired"); } private static void NotifyIconInteracted(object sender, EventArgs e) { Console.WriteLine("Icon clicked"); } } }
while（true）锁定主线程。
尝试用while替换while（true）块
Application.Run();
