c# - C#中的事件数组？

Question

基本上:

public delegate void RecvCommandHandler (ChatApplication sender, byte[] content);
event RecvCommandHandler[] commands = new RecvCommandHandler[255];

我想为每个命令编号激活不同的方法/功能，但我真的不确定语法。我应该怎么做？

我想我会为这个问题选择一组代表，但这个问题仍然很有趣。

您可以创建一个带有运算符重载的类数组来模拟您感兴趣的行为...

public delegate void EventDelegate(EventData kEvent);

public class EventElement
{
    protected event EventDelegate eventdelegate;

    public void Dispatch(EventData kEvent)
    {
        if (eventdelegate != null)
        {
            eventdelegate(kEvent);
        }
    }

    public static EventElement operator +(EventElement kElement, EventDelegate kDelegate)
    {
        kElement.eventdelegate += kDelegate;
        return kElement;
    }

    public static EventElement operator -(EventElement kElement, EventDelegate kDelegate)
    {
        kElement.eventdelegate -= kDelegate;
        return kElement;
    }
}

public EventElement[] commands = new EventElement[255];

commands[100] += OnWhatever;
commands[100].Dispatch(new EventData());
commands[100] -= OnWhatever;
