Question

在手动映射中，我可以执行以下操作：

//LINQ Query here...
.Select(x => new ViewModel
{
    BooleanProperty = x.OtherProperty > 3
})

如果OtherProperty为4或更大，则

BooleanProperty将为true，否则为false。我一直无法弄清楚如何在AutoMapper中执行此操作。我尝试了以下方法：

.ForMember(dest => dest.BooleanProperty, opt => opt.ResolveUsing(src => src.OtherProperty > 3))

.ForMember(dest => dest.BooleanProperty, opt => opt.MapFrom(src => src.OtherProperty > 3))

.ForMember(dest => dest.BooleanProperty, opt => opt.ResolveUsing<BooleanPropertyResolver>())

BooleanPropertyResolver：

public class CustomResolver : IValueResolver<Address, AddressFormViewModel, bool>
{
    public bool Resolve(Address source, AddressFormViewModel destination, bool member, ResolutionContext context)
    {
        return source.OtherProperty > 3;
    }
}

对于所有其他方法，当OtherProperty为4时，BooleanProperty仍为false。如何在AutoMapper顶部的手动映射中复制功能？

如何在AutoMapper中使用自定义逻辑映射其他属性的属性？
