在Visual Studio中触发事件时中断调试器

你不能为在应用程序中引发的所有事件注册一个全局处理程序，但是你可以为静态事件注册你自己的处理程序，在Reflection的帮助下:

public class Program
{
    public static void Main(string[] args)
    {
        MethodInfo handler = typeof(Program).GetMethod("GlobalEventHandler");
        IEnumerable<EventInfo> events = AppDomain.CurrentDomain
            .GetAssemblies()
            .Select(a => a.GetTypes()
                          .Select(t => t.GetEvents(
                                            BindingFlags.Public |
                                            BindingFlags.NonPublic |
                                            BindingFlags.Static)
                                         .Where(e => typeof(EventHandler)
                                                     .IsAssignableFrom(e.EventHandlerType))))
            .SelectMany(e => e)
            .SelectMany(e => e);
        foreach (EventInfo evt in events)
            evt.GetAddMethod(true).Invoke(null, new object[]
            {
                Delegate.CreateDelegate(evt.EventHandlerType, null, handler)
            });
    }
    public static void GlobalEventHandler(object sender, EventArgs args)
    {
        Debugger.Break(); // <-- When a static event is fired, the application will break here
        Console.WriteLine("An event was fired!");
    }

支持的静态事件并不多。
