在C#中从不同的类中引发类的事件

public delegate void MyEventHandler(object sender, EventArgs e);

public class MyClass
{
    public event MyEventHandler MyEvent;

    public void RaiseEvent()
    {
        // 触发事件
        MyEvent?.Invoke(this, EventArgs.Empty);
    }
}

public class AnotherClass
{
    public void SubscribeEvent(MyClass myClass)
    {
        myClass.MyEvent += HandleEvent;
    }

    private void HandleEvent(object sender, EventArgs e)
    {
        // 处理事件
        Console.WriteLine("Event handled!");
    }
}

MyClass myClass = new MyClass();
AnotherClass anotherClass = new AnotherClass();
anotherClass.SubscribeEvent(myClass);

myClass.RaiseEvent(); // 引发事件
