Question

我已经使用此模型将一个用户添加到名为users的mongodb集合中：

    [BsonRepresentation(BsonType.ObjectId)]
    public ObjectId _id { get; set; }
    [Display(Name = "Password:")]
    public string Password { get; set; }
    [Display(Name = "Confirm:")]
    public string ConfirmPassword { get; set; }
    [Display(Name = "Email:")]
    public string Email { get; set; }
    [Display(Name = "Username:")]
    public string UserName { get; set; }
    [Display(Name = "Firtname:")]
    public string Firstname { get; set; }
    [Display(Name = "Lastname:")]
    public string Lastname { get; set; }
    [Display(Name = "Country:")]
    public string Country { get; set; }
    [Display(Name = "City:")]
    public string City { get; set; }
    [Display(Name = "Birthdate:")]
    public int Birthdate { get; set; }
    public List<Team> Teams { get; set; }

你可以看到它里面还有一个团队列表。所以现在我使用这段代码来获取用户：

         var query_id = Query.EQ("_id", ObjectId.Parse(Session["ID"].ToString()));
        User entity = Context.Users.FindOne(query_id);

现在我想用我的团队模型中的数据向mongodb对象添加一个列表：

  public int TeamID { get; set; }
    public string TeamName { get; set; }
    public string UserName { get; set; }
    public int LeagueID { get; set; }

    public Points Points = new Points();

    public List<Player> Player { get; set; }

如何在mongodb集合中将team-modeldata添加到我的userobject？

我建议使用MongoDB的LINQ / AutoMapping功能。

var databaseClient = new MongoClient(DatabaseConnectionString);
var server = databaseClient.GetServer();
var database = server.GetDatabase("Users");
var collection = database.GetCollection<User>("users");

var user = collection.AsQueryable().First(o => o._id == YOURSESSIONID);

user.Teams.Add(new Team { TeamID = 0, TeamName = "Some Team" });

使用模型将数组添加到mongodb
