在c#中在运行时创建eventhandler

using System;

namespace RuntimeEventHandler
{
    class Program
    {
        static void Main(string[] args)
        {
            MyClass myClass = new MyClass();

            // 使用匿名方法创建 event handler
            myClass.MyEvent += delegate (object sender, EventArgs e)
            {
                Console.WriteLine("Event triggered using anonymous method");
            };

            // 使用 Lambda 表达式创建 event handler
            myClass.MyEvent += (sender, e) =>
            {
                Console.WriteLine("Event triggered using Lambda expression");
            };

            // 使用自定义方法创建 event handler
            myClass.MyEvent += MyCustomEventHandler;

            myClass.TriggerEvent();
        }

        static void MyCustomEventHandler(object sender, EventArgs e)
        {
            Console.WriteLine("Event triggered using custom method");
        }
    }

    class MyClass
    {
        public event EventHandler MyEvent;

        public void TriggerEvent()
        {
            MyEvent?.Invoke(this, EventArgs.Empty);
        }
    }
}
