Question

当我使用此映射时

           Mapper.CreateMap<DataSourceConfigurationContract, DataSourceConfigurationContract>().ForMember(x => (object)x.DatabaseTypeException, opt => opt.Ignore())
                                                                                               .ForMember(x => (object)x.DatabaseType, opt => opt.Ignore());

           var mappedValue = Mapper.Map<DataSourceConfigurationContract, DataSourceConfigurationContract>(dataSourceConfiguration);

这个班级

public sealed class DataSourceConfigurationContract {
  public string Name { get; set; }
  public string ConnectionString { get; set; }
  public string ConnectionType  { get; set; }
  public DataSourcePropertyContractCollection Properties { get; set; }
  public DataSourceAreaConfigurationContractCollection Areas { get; set; }
  public UserContractCollection AllowedUsers{ get; set; }
  public DataSourceType? DatabaseType { get; set; }
  public ExceptionContract DatabaseTypeException { get; set; }
  public DataSourceType DataSourceType { get; set; } }

应忽略某些属性（例如，区域）。字符串属性似乎始终正确映射。我做错了什么？

Answer 1

AutoMapper仅支持开箱即用的以下集合：http://automapper.codeplex.com/wikipage?title=Lists%20and%20Arrays&referringTitle=Home。我猜你没有复制的属性是XXXCollection类型。

您可以通过为您的收藏类型创建自定义类型转换器来解决此问题：http://automapper.codeplex.com/wikipage?title=Custom%20Type%20Converters&referringTitle=Home

Answer 2

对于您的收藏品，您需要执行与以下类似的操作（取自我最近处理过的一些代码）：

Mapper.CreateMap<List<QuizItemTypeModel>, List<Quiz.DataContracts.QuizItemType>>()
                .Include<QuizDataCompositeModel, Quiz.DataContracts.QuizDataComposite>();

QuizDataCompositeModel和Quiz.DataContracts.QuizDataComposite都延伸List<"RespectiveType">

Answer 3

这很简单：

Mapper.CreateMap<DataSourceAreaConfigurationContract, DataSourceAreaConfiguration>();
Mapper.CreateMap<DataSourceConfigurationContract, DataSourceConfigurationContract>()
      .ForMember(dest => dest.Areas, opt => opt.UseDestinationValue());
