Question

我如何配置automapper来映射它：

class Source { Guid Id; double Price; }

对此：

class Destination { Guid Id; DestinationDifference Difference; }


class DestinationDifference { decimal Amount; }

首先：您应该阅读有关如何发布问题以及应添加哪些信息的常见问题解答。（不，我不是下来的人）

以下是如何使映射正常工作的示例。请注意，我已经更改了一些类，因为AutoMapper需要属性。

Source source = new Source();
source.Id = Guid.NewGuid();
source.Price = 10.0;

Mapper.Initialize(x => x.CreateMap<Source, Destination>()
    .ForMember(a => a.Difference,
        b => b.MapFrom(s => new DestinationDifference() { Amount = (decimal)s.Price })));

Destination destination = Mapper.Map<Source, Destination>(source);

类：

class Source
{
    public Guid Id { get; set; }
    public double Price { get; set; }
}

class Destination
{
    public Guid Id { get; set; }
    public DestinationDifference Difference { get; set; }
}

class DestinationDifference
{
    public decimal Amount { get; set; }
}

Automapper自定义对象
