如何通过Linq在MongoDB中查询BsonExtraElements

using MongoDB.Driver;
using MongoDB.Driver.Linq;

var client = new MongoClient("mongodb://localhost:27017");
var database = client.GetDatabase("your_database_name");

var collection = database.GetCollection<BsonDocument>("your_collection_name");

var query = collection.AsQueryable()
                     .Where(x => x.Contains("BsonExtraElements"));

var query = collection.AsQueryable()
                     .Where(x => x.Contains("BsonExtraElements") && x["SomeField"] == "SomeValue");

var result = query.ToList();
