c# - 覆盖 CreateMap - Automapper

Question

我有以下地图。所有十进制类型数字都有 2 个小数位。

CreateMap<decimal, decimal>().ConvertUsing(x => decimal.Round(x, 2, MidpointRounding.AwayFromZero));

但有时，我需要更多小数位，例如

CreateMap<T, R>.ForMember(x => x.Total, x => x.MapFrom(x => decimal.Round(x.Items.Sum(x => x.Price * x.Quantity), 3, MidpointRounding.AwayFromZero)))

是否可以在某些“CreateMap”中覆盖全局 CreateMap？谢谢

One option is that when you call the mapper.Map, you can provide options that override the current map profile using the inline mapping like so.

_mapper.Map(T, R, opt => opt.ConfigureMap().ForMember(x => x.Total, x => x.MapFrom(x => decimal.Round(x.Items.Sum(x => x.Price * x.Quantity), 3, MidpointRounding.AwayFromZero)));
