c# - Automapper 帮助映射复杂的 c# 对象

Question

我正在尝试使用 Automapper 将 Vehicle 对象映射到 Motor 对象

public class Range<T>
{
    public T Min { get; set; }
    public T Max { get; set; }
}

public Enum SpeedType
{
    [Display(Name = "-")] Unknown = 0,
    [Display(Name = "M")] Manual= 1,
    [Display(Name = "A")] Automatic= 2
}

public class Vehicle
{
    public Range<string> Speed { get; set; }
}

public class Motor
{
    public Range<SpeedType?> Speed { get; set; }
}

我尝试使用 MapFrom(阅读文档)但没有成功。有人能指出我正确的方向吗？我什至不确定这是否可以使用 Automapper 进行映射。我过去曾使用 automapper 进行简单映射。

这对我有用:

Mapper.Initialize(cfg =>
{
    cfg.CreateMap<string, SpeedType?>().ConvertUsing(speed =>
    {
        switch (speed)
        {
            case "M": return SpeedType.Manual;
            case "A": return SpeedType.Automatic;
            default: return SpeedType.Unknown;
        }
    });

    cfg.CreateMap<Range<string>, Range<SpeedType?>>();
    cfg.CreateMap<Vehicle, Motor>();
});

var vehicle = new Vehicle
{
    Speed = new Range<string>
    {
        Min = "M",
        Max = "A"
    }
};

var motor = Mapper.Map<Vehicle, Motor>(vehicle);
