AutoMapper在.NetCore中實現兩個對象的映射（復制）

添加NuGet包：AutoMapper

類1：

public class AuditLog
  {
    public string SystemTag { get; set; }

    public string BeforeContent { get; set; }

    public string AfterContent { get; set; }

    public DateTime OperateDateTime { get; set; }
    }
}

類2：

public class QueryAuditLogDto
{
    public string SystemTag { get; set; }

    public string BeforeContent { get; set; }

    public string AfterContent { get; set; }

    public string [] OperateDateTime { get; set; }
}

把類1復制給類2，並改變其中字段的類型或表現形式

          List<Models.AuditLog> listAuditLog = db.Query<Models.AuditLog>( SourceSql).ToList();
          List<QueryAuditLogDto> listAuditLogDto = new List<QueryAuditLogDto>();
          var config = new MapperConfiguration( cfg => cfg.CreateMap<Models.AuditLog, QueryAuditLogDto>()
            .ForMember(d=>d.BeforeContent ,opt=>opt.MapFrom(src=>src.BeforeContent.Replace( "{\"", "" ).Replace( "\"}", "" ).Replace( "\":\"", "=" ).Replace( "\",\"", "," ) ) )
            .ForMember(d=>d.AfterContent,opt=>opt.MapFrom(src=>src.AfterContent.Replace( "{\"", "" ).Replace( "\"}", "" ).Replace( "\":\"", "=" ).Replace( "\",\"", "," ) ) )
            .ForMember(d=>d.OperateDateTime,opt=>opt.MapFrom(src=> new string[] { src.OperateDateTime.ToString( "yyyy-MM-dd HH:mm:ss" ) } ))
          );
          var mapper = config.CreateMapper();
          listAuditLogDto = mapper.Map<List<QueryAuditLogDto>>( listAuditLog );
