我正在尝试将嵌入对象插入、更新和删除(CRUD)到现有的 Monogodb 文档中,假设为客户添加多个地址,

{
   "_id":ObjectId("52ffc33cd85242f436000001"),
   "contact": "987654321",
   "dob": "01-01-1991",
   "name": "Tom Benzamin",
   "address": [
      {
         "building": "22 A, Indiana Apt",
         "pincode": 123456,
         "city": "Los Angeles",
         "state": "California"
      },
      {
         "building": "170 A, Acropolis Apt",
         "pincode": 456789,
         "city": "Chicago",
         "state": "Illinois"
      }
   ]
} 

我可以使用命令行(添加多个地址)来完成,但是通过 mvc 核心,我只能在使用 InserOne 插入文档时插入单个地址,也可以使用 ReplaceOne 更新它,但我可以添加第二个或第三个地址。

这是我的 c# 类和接口(服务)

public class Customer
    {
        [BsonId]
        [BsonRepresentation(BsonType.ObjectId)]
        public string Id { get; set; }

        [BsonElement("contact")]
        [Required]
        public string Contact { get; set; }

        [BsonElement("dob")]
        [Required]
        public string Dob { get; set; }


        [BsonElement("name")]
        public string Name { get; set; }


        public Addresses Address { get; set; }



    }
        public class Addresses
        {
            public string Building { get; set; }
            public string Pincode { get; set; }
            public string City { get; set; }
            public string State { get; set; }

        }



}

和服务

 public Customer Create(Customer c)
{
  customers.InsertOne(c);
  return c;
}

 public void Update(string id, Customer c)
 { 
    customers.ReplaceOne(cutomer => cutomer.Id == id, c);
 }
