返回单一值是良好的编程习惯
原代码:
public LotteryViewModel ValidateLottery(LotteryBaseData baseData, int authTime, out GetDataForValidateLotteryResultModel data)
{
....
}
重构后代码:
public Tuple<LotteryViewModel, GetDataForValidateLotteryResultModel> ValidateLottery(LotteryBaseData baseData, Lottery_AuthTimeEnum authTime )
{
...
}
