Event基类设计

===========================================================
using System;
public  class BaseEvent<T> where T: BaseEvent<T>
{
    //事件基类
    private static Action mOnEvent;
    /// <summary>
    /// 添加监听器
    /// </summary>
    /// <param name="listener"></param>
    public static void AddListener( Action listener)
    {
        mOnEvent += listener;
    }
    /// <summary>
    /// 移除监听器
    /// </summary>
    /// <param name="listener"></param>
    public static void RemoveListener( Action listener)
    {
        mOnEvent -= listener;
    }
    /// <summary>
    /// 触发事件
    /// </summary>
    public static void SendEvent()
    {
       mOnEvent?.Invoke();
    }
    /// <summary>
    /// 销毁
    /// </summary>
    void Destroy()
    {
        mOnEvent = null;
