public class PropertySet<N, T> where N : struct ,IConvertible  //基类                               where T : IComparable{    protected T[] mValues;    protected Action<T>[] mActions;    public PropertySet(N maxCount)    {        int count = ToIndex(maxCount);        mValues = new T[count];        mActions = new Action<T>[count];    }    public void AddChanageEvent(N key, Action<T> handler)     {        mActions[ToIndex(key)] += handler;    }    public void RemoveChangeEvent(N key, Action<T> handler)    {        mActions[ToIndex(key)] -= handler;    }    public virtual int ToIndex(N key)    {        return key.ToInt32(null); //12bytes GC Alloc    }    public virtual T this[N key]    {        get        {            return mValues[ToIndex(key)];        }        set        {            int index = ToIndex(key);            if (value.CompareTo(mValues[index]) != 0)            {                mValues[index] = value;                if (mActions[index] != null)                {                    mActions[index](value);                }            }        }    }}public class PlayerPropertySet : PropertySet<EPlayerProperty, float>{    public PlayerPropertySet() : base(EPlayerProperty.Max){mCryptoValues = new FloatCryptoWrapper[(int)EPlayerProperty.Max];for (int i = 0; i < mCryptoValues.Length; i++){mCryptoValues[i] = new FloatCryptoWrapper(0.0f);}}    public override int ToIndex(EPlayerProperty key)    {        return (int)key;    }    public override float this[EPlayerProperty key]    {        get        {            return mCryptoValues[ToIndex(key)].Value;        }        set        {            int index = ToIndex(key);if ((mCryptoValues[ToIndex(key)].Value) != value)            {mCryptoValues[ToIndex(key)].Value = value;                if (mActions[index] != null)                {                    mActions[index](value);//触发时间，括号为传递参数值                }            }        }    }    protected FloatCryptoWrapper[] mCryptoValues;}

用法

//注册事件，并使用PlayerPropertySet PropertySet;Player.PropertySet.AddChanageEvent(EPlayerProperty.Health, OnHealthChange);void OnHealthChange(float newValue){ //写处理逻辑}

赋值、取值float test = PropertySet[EPlayerProperty.Health];PropertySet[EPlayerProperty.Health] = 1f;
