使用.net核心和mongodb，有没有办法只更新我在json中传递的字段？

using MongoDB.Driver;

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

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

var filter = Builders<BsonDocument>.Filter.Eq("_id", ObjectId.Parse("your_document_id"));

var update = Builders<BsonDocument>.Update.Set("field1", "new_value1")
                                           .Set("field2", "new_value2")
                                           .Set("field3", "new_value3");

collection.UpdateOne(filter, update);
