Question

无论如何都要用automapper来压缩它吗？它刚刚变大。

        Mapper.CreateMap<PagedResult<Headline>, PagedResult<HeadlineModel>>();
        Mapper.CreateMap<PagedResult<Event>, PagedResult<EventModel>>();
        Mapper.CreateMap<PagedResult<GymCourt>, PagedResult<GymCourtModel>>();
        Mapper.CreateMap<PagedResult<Gym>, PagedResult<GymModel>>();
        Mapper.CreateMap<PagedResult<EventGymCourt>, PagedResult<EventGymCourtModel>>();
        Mapper.CreateMap<PagedResult<Division>, PagedResult<DivisionModel>>();
        Mapper.CreateMap<PagedResult<Team>, PagedResult<TeamModel>>();
        Mapper.CreateMap<PagedResult<DivisionTeam>, PagedResult<DivisionTeamModel>>();
        Mapper.CreateMap<PagedResult<MemberTeam>, PagedResult<MemberTeamModel>>();
        Mapper.CreateMap<PagedResult<TeamCoach>, PagedResult<TeamCoachModel>>();
        Mapper.CreateMap<PagedResult<DivisionAsset>, PagedResult<DivisionAssetModel>>();
        Mapper.CreateMap<PagedResult<EventAsset>, PagedResult<EventAssetModel>>();
        Mapper.CreateMap<PagedResult<Event>, PagedResult<ApiEvent>>();
        Mapper.CreateMap<PagedResult<Price>, PagedResult<PriceModel>>();
        Mapper.CreateMap<PagedResult<DivisionPrice>, PagedResult<DivisionPriceModel>>();
        Mapper.CreateMap<PagedResult<EventPrice>, PagedResult<EventPriceModel>>();
        Mapper.CreateMap<PagedResult<Division>, PagedResult<ApiDivision>>();
        Mapper.CreateMap<PagedResult<Data.Entities.Player>, PagedResult<PlayerModel>>();

Answer 1

您可以做的是使用扩展方法。如果你添加这个类：

public static class MappingExtensions
{
    public static IMappingExpression<TSrc, TDest> IncludePagedResultMapping<TSrc, TDest>(this IMappingExpression<TSrc, TDest> expression)
    {
        Mapper.CreateMap<PagedResult<TSrc>, PagedResult<TDest>>()
            .ForMember(dest => dest.HasMoreResults, opt => opt.MapFrom(src => src.HasMoreResults))
            .ForMember(dest => dest.NextPage, opt => opt.MapFrom(src => src.NextPage));

        return expression;
    }
}

然后您可以将分页映射作为实体的一部分包含在模型映射中，即：

Mapper.CreateMap<Headline, HeadlineModel>().IncludePagedResultMapping();
Mapper.CreateMap<Event, EventModel>().IncludePagedResultMapping();
Mapper.CreateMap<GymCourt, GymCourtModel>().IncludePagedResultMapping();
Mapper.CreateMap<Player, PlayerModel>().IncludePagedResultMapping();

据我所知，Automapper中没有自定义映射器注册约定的支持，但是你可以通过一些反思将它干掉一点：

var mappingDictionary = new Dictionary<Type, Type>
{
    {typeof (Headline), typeof (HeadlineModel)},
    {typeof (Event), typeof (EventModel)},
    //...
};
foreach (var sourceType in mappingDictionary.Keys)
{
    Mapper.CreateMap(
       typeof (PagedResult<>).MakeGenericType(sourceType),
       typeof (PagedResult<>).MakeGenericType(mappingDictionary[sourceType]));
}

或者如果您始终遵循惯例Headline - ＆gt; HeadlineModel等。通过更多反射，您无需手动构建映射：

var modelAssembly = Assembly.GetAssembly(typeof(HeadlineModel));
var otherAssembly = Assembly.GetAssembly(typeof(Headline));
foreach (var destinationType in modelAssembly.GetTypes()
    .Where(t => t.Namespace == "ModelNaspace" && t.Name.EndsWith("Model")))
{
    var destinationName = destinationType.Name.Replace("Model", "");
    var sourceType = otherAssembly.GetTypes()
        .SingleOrDefault(t => t.Namespace == "OtherNamespace" && t.Name == destinationName);

    if (sourceType == null)
    {
        //log warning
        continue;
    }

    Mapper.CreateMap(
       typeof (PagedResult<>).MakeGenericType(sourceType),
       typeof (PagedResult<>).MakeGenericType(destinationType));
}

Answer 3

我不敢。在某些时候，您必须告诉AutoMapper您的类映射。

如果您要整合Global.aspx（假设您在Asp.Net中使用AutoMapper），您可能需要尝试使用Bootstrapper。
