[英]Map a dictionary's values to a list using AutoMapper
I have a Database Object which has a dictionary of properties which I need to map to a list object within a new object. 我有一个数据库对象,该对象具有属性字典,我需要将其映射到新对象中的列表对象。 My structure (simplified) looks like this: 我的结构(简化)如下所示:
public class DbObject { // The source
public Dictionary<string, DbCustomProperty> customProperties;
}
public class DbCustomProperty {
public string Key;
public string Value;
}
public class DTOObject { // The destination
public List<DTOCustomProperty> DTOCustomProperties;
}
public class DTOCustomProperty {
public string Key;
public string Value;
}
As you can see, I would like to map DbObject (the source) onto a DTOObject (the destination). 如您所见,我想将DbObject(源)映射到DTOObject(目标)上。 The problem is that my DBObject contains a dictionary where the values are the property that I've like to map into a list. 问题是我的DBObject包含一个字典,其中的值是我想映射到列表中的属性。
eg. 例如。 dBObject.CustomProperties.Values --> dtoObject.CustomProperties dBObject.CustomProperties.Values-> dtoObject.CustomProperties
Can this be acheieved through AutoMapper? 可以通过AutoMapper实现吗?
You can use: 您可以使用:
AutoMapper.CreateMap<IGrouping<string, DbCustomProperty>, DTOCustomProperty>()
.ForMember(dest => dest.Key, opt => opt.MapFrom(src => src.Key))
.ForMember(dest => dest.Value, opt => opt.MapFrom(src => src.Value)));
