我在c#中更新一條數據的時候，怎么更新一個json數組呢？比如我數據庫中已經有一條數據了。{ "_id" : ObjectId("58183b67afa78926f9ea8513"), "name" : "joy", "age" : 23 },這樣一條數據，我想要在插入一個字段，這個字段是一個數組，這樣的："add1":[{...},{....}]。。這樣該怎么更新呢？我看c#驅動里面有個Builders<BsonDocument>.Update.Combine()這個方法，我這樣寫的：var up4 = Builders<BsonDocument>.Update.Set("address1.street4", "East 31st Street4");var up5 = Builders<BsonDocument>.Update.Set("address1.street5", "East 31st Street5");var up6 = Builders<BsonDocument>.Update.Set("address1.street6", "East 31st Street6");var update = Builders<BsonDocument>.Update.Combine(up4, up5, up6);但是我用這個方法只能更新成"add1":{... , .... , ....}這樣欸。比如這種"address1" : { "street" : "East 31st Street", "street1" : "East 31st Street", "street2" : "East 31st Street2", "street3" : "East 31st Street3", "street4" : "East 31st Street4" }
