在Automapper CreateMap和Projection中使用枚举作为条件

使用AutoMapper v6.1

无需硬编码该值来代替枚举( (int)POStatusOptions.Ordered ),如何使用投影完成此地图:

CreateMap<WorkOrderDetail, WorkOrderDetailsListViewModel>(MemberList.Destination)
.ForMember(vm => vm.QtyOnPOs, opt => opt.MapFrom(entity =>
    entity.Item.PODetails
        .Where(pod => pod.POHeader.StatusId >= (int)POStatusOptions.Ordered)
        .Sum(pod => pod.QtyOrdered)
        )))

我对automapper的配置是使用配置文件。所以我有

我的配置类:

public static class AutoMapperConfiguration
{
    public static void Configure()
    {
        //see https://github.com/AutoMapper/AutoMapper/wiki/Configuration
        //see https://github.com/AutoMapper/AutoMapper/wiki/Configuration-validation 
        Mapper.Initialize(am =>
        {
            am.AddProfile<AutoMapperViewModelProfile>();
            am.AddProfile<AutoMapperViewModelProfileAdmin>();
        });

        //uncomment this during testing to get a list of all errors in the browser when you run any page in otis
        Mapper.AssertConfigurationIsValid();
    }    
}

它被调用 Application_Start() 例如: AutoMapperConfiguration.Configure();

我的个人资料类别:

public class AutoMapperViewModelProfile : Profile
{
    public AutoMapperViewModelProfile()
    {
        CreateMap<WorkOrderDetail, WorkOrderDetailsListViewModel>(MemberList.Destination)
        .ForMember(vm => vm.QtyOnPOs, opt => opt.MapFrom(entity =>
            entity.Item.PODetails
            .Where(pod => pod.POHeader.StatusId >= (int)POStatusOptions.Ordered)
            .Sum(pod => pod.QtyOrdered)
        )))
}
