MongoDB Bson在C＃中创建

Question

I am new to MongoDB, what I would like to do is Under property address I would like to save person's name and age, it might be one person per property or more than one, so I am trying with just name first but I am getting error.

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# code

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() } }
        } }
    };

but I am getting bellow error

An Array value cannot be written to the root level of a BSON document.

look forward to you help.

AFAIK, You con use BsonArray(IEnumerable<string> strings) constructor like this:

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)}
};

That result is:

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