问题描述
MongoDB驱动程序指南建议将类映射注册为自动映射通过
The MongoDB driver tutorial suggests to register class maps to automap via
BsonClassMap.RegisterClassMap<MyClass>();
我想自动映射给定名称空间的所有类,而无需为每个类显式写下RegisterClassMap.目前有可能吗?
I would like to automap all classes of a given namespace without explicitly writing down RegisterClassMap for each class. Is this currently possible?
推荐答案
您不需要写BsonClassMap.RegisterClassMap<MyClass>();
,因为默认情况下所有类都将自动映射.
You don't need write BsonClassMap.RegisterClassMap<MyClass>();
, because all classes will be automapped by default.
需要自定义序列化时应使用RegisterClassMap
:
You should use RegisterClassMap
when you need custom serialization:
BsonClassMap.RegisterClassMap<MyClass>(cm => {
cm.AutoMap();
cm.SetIdMember(cm.GetMemberMap(c => c.SomeProperty));
});
您还可以使用属性来创建管理序列化(对我来说,本机看起来更原生):
Also you can use attributes to create manage serialization(it's looks like more native for me):
[BsonId] // mark property as _id
[BsonElement("SomeAnotherName", Order = 1)] //set property name , order
[BsonIgnoreExtraElements] // ignore extra elements during deserialization
[BsonIgnore] // ignore property on insert
您还可以创建在自动映射过程中使用的全局规则,如下所示:
Also you can create global rules thats used during automapping, like this one:
var myConventions = new ConventionProfile();
myConventions.SetIdMemberConvention(new NoDefaultPropertyIdConvention());
BsonClassMap.RegisterConventions(myConventions, t => true);
我仅使用属性和约定来管理序列化过程.
I am using only attributes and conventions to manage serialization process.
