具有自定义attribute[AutoMapper]的AutoMapper :如何在属性上添加条件

public class SourceClass
{
    public int Id { get; set; }
    [AutoMapper]
    public string Name { get; set; }
}

public class DestinationClass
{
    public int Id { get; set; }
    public string Name { get; set; }
}

public class AutoMapperProfile : Profile
{
    public AutoMapperProfile()
    {
        CreateMap<SourceClass, DestinationClass>()
            .ForMember(dest => dest.Name, opt =>
            {
                opt.Condition(src => src.Name != null); // 添加条件，只有当源属性Name不为null时才进行映射
                opt.MapFrom(src => src.Name);
            });
    }
}

// 在使用AutoMapper进行映射之前，需要先进行配置
var config = new MapperConfiguration(cfg =>
{
    cfg.AddProfile<AutoMapperProfile>();
});

// 创建映射器
var mapper = config.CreateMapper();

// 进行对象之间的映射
var source = new SourceClass { Id = 1, Name = "John" };
var destination = mapper.Map<DestinationClass>(source);
