C#如何在DLL中公开事件

public class MyEventClass
{
    // 定义事件委托
    public delegate void MyEventHandler(object sender, EventArgs e);

    // 声明事件
    public event MyEventHandler MyEvent;

    // 触发事件的方法
    protected virtual void OnMyEvent(EventArgs e)
    {
        MyEvent?.Invoke(this, e);
    }
}

public class MyClass
{
    private MyEventClass myEventObject;

    public MyClass()
    {
        myEventObject = new MyEventClass();
        myEventObject.MyEvent += MyEventHandler;
    }

    private void MyEventHandler(object sender, EventArgs e)
    {
        // 处理事件的逻辑
    }
}

public class Program
{
    static void Main(string[] args)
    {
        MyClass myClass = new MyClass();
        myClass.myEventObject.OnMyEvent(EventArgs.Empty);
    }
}
