将平面MongoDB文档反序列化为嵌套的C#类

using MongoDB.Bson;
using MongoDB.Bson.Serialization.Attributes;
using MongoDB.Driver;

// 定义嵌套的C#类
public class Person
{
    [BsonId]
    public ObjectId Id { get; set; }

    public string Name { get; set; }

    public int Age { get; set; }

    public Address Address { get; set; }
}

public class Address
{
    public string Street { get; set; }

    public string City { get; set; }

    public string Country { get; set; }
}

// 反序列化MongoDB文档为C#类
public Person DeserializeDocument(BsonDocument document)
{
    var person = BsonSerializer.Deserialize<Person>(document);
    return person;
}

// 使用示例
var client = new MongoClient("mongodb://localhost:27017");
var database = client.GetDatabase("mydb");
var collection = database.GetCollection<BsonDocument>("mycollection");

var document = collection.Find(new BsonDocument()).FirstOrDefault();
var person = DeserializeDocument(document);

// 对person对象进行操作和管理
Console.WriteLine(person.Name);
Console.WriteLine(person.Age);
Console.WriteLine(person.Address.Street);
Console.WriteLine(person.Address.City);
Console.WriteLine(person.Address.Country);
