MongoDB Bson在C＃中創建

Question

我是MongoDB的新手，我想做的是在財產地址下，我想保存一個人的姓名和年齡，它可能是每個財產一個人或一個以上，所以我嘗試僅使用名字，但是錯誤。

JSON

{
    "property": "This is property address",
    "address1": "address 1",
    "address2": "address 2",
    "city": "city name",
    "people": [
        "Person 1",
        "Person 2",
        "Person 3",
        "Person 4"
    ]
}

C＃代碼

List<string> names = new List<string>();
names.Add("person 1");
names.Add("person 2");
names.Add("person 3");
names.Add("person 4");

var document = new BsonDocument {

    {"property", "10" },
    {"address", "this is address 1" },
    {"city", "city name" },
    {"Family Members", new BsonArray {
        new BsonDocument { {"name", names.ToBsonDocument() } }
        } }
    };

但我收到以下錯誤消息

數組值不能寫到BSON文檔的根目錄下。

期待您的幫助。

AFAIK，您可以像這樣使用BsonArray(IEnumerable<string> strings)構造函數：

var names = new[]
{
    "Person 1",
    "Person 2",
    "Person 3",
    "Person 4"
};

var document = new BsonDocument
{
    {"property", "10"},
    {"address", "this is address 1"},
    {"city", "city name"},
    {"Family Members", new BsonArray(names)}
};

結果是：

{ 
    {
        "property" : "10",
        "address" : "this is address 1",
        "city" : "city name",
        "Family Members" : ["Person 1", "Person 2", "Person 3", "Person 4"]
    }
}
