c＃BsonSerializer：通过支持字段反序列化

Question

I'm starting to work with MongoDB using official c# driver. The problem is that I can't find a way to make bsonseriazer use fields (not properties) for setting the deserialized data and at the same time being able to use LINQ Api.

When mapping my class, I use BsonClassMap.FieldMap(). But this doesn't allow to use LINQ, since public properties remain unmapped. Is there a way in BsonSerializer to do mappings based on properties, but at the same time specify that these should be set directly via their backing fields?

The reason I want to use fields for deserialization, is to omit custom validation rules that might be checked in setter.

Answer 1

1. I think you should keep those validation rules even when the data comes from your own database. It's much cleaner, less bug-prone and is more secure.

2. You can create your own BsonSerializer s (or extend an existing one) that act which ever way you want. I've made several of those and it's really simple.

3. You can have a bool _isInitialized = false; in your DTO s that you set to true right after you get items from the MongoDB driver and forgo the validation rules until it is set.

I don't see another way to "split" the mapping to both the properties (for Linq ) and data members (for serialization) and I recommend the first option.
