在映射配置中手动指定计算属性进行映射

//示例：定义计算属性 public class SourceModel { public int X { get; set; } public int Y { get; set; } public int Sum => X + Y; }

public class DestinationModel { public int X { get; set; } public int Y { get; set; } public int Sum { get; set; } }

//添加映射配置 var config = new MapperConfiguration(cfg => { cfg.CreateMap() .ForMember(dest => dest.Sum, opt => opt.MapFrom(src => src.Sum)); });

//使用Automapper进行映射 var source = new SourceModel { X = 1, Y = 2 }; var mapper = config.CreateMapper(); var dest = mapper.Map(source);

//在Dest中获取计算属性 var sum = dest.Sum; //3
