关于EmitMapper，映射配置

        public static T Snapshoot<T>(this XtraForm form, T obj)
        {
            var config = new DefaultMapConfig();
            config.SetConfigName("AllField");
            var map = EmitMapper.ObjectMapperManager.DefaultInstance.GetMapper<T, T>(config);
            var config2 = map.MapperImpl.MappingConfigurator as DefaultMapConfig;

            return  map.Map(obj);
        }
        public static T Restore<T>(this XtraForm form, T src, T tag)
        {
            var config = new DefaultMapConfig().IgnoreMembers<T, T>(new string[] { "EntityKey", "EntityState" });
            config.SetConfigName("NoEntityKey");
            var map = EmitMapper.ObjectMapperManager.DefaultInstance.GetMapper<T, T>(config);
            var config2 = map.MapperImpl.MappingConfigurator as DefaultMapConfig;

            return map.Map(src,tag);
        }

如果不指定config名称，那么后一次调用不会覆盖前一次调用的config设置
