c# List Sort 简单实现

vtTick.Sort((Comparison<CtpTick>)delegate(CtpTick a,CtpTick b)                    {                        if (a.UpdateTime < b.UpdateTime)                            return -1;                        if (a.UpdateTime > b.UpdateTime)                            return 1;                        if (a.doneVolume < b.doneVolume)                            return -1;                        if (a.doneVolume > b.doneVolume)                            return 1;                        //下面是无奈之举，都怪CTP没有updSerial,加个序号很难吗！？                        if (a.WriteTime < b.WriteTime)                            return -1;                        if (a.WriteTime > b.WriteTime)                            return 1;                        return 0;                    });
