无法在对象列表

Question

对象类

 namespace BigDtaHandler_Test
    {

        [BsonIgnoreExtraElements]
        class ActiveWin
        {

            public string ActID { get; set; }
            public string ActWinName { get; set; }

            public DateTime ActWinDate { get; set; } 
            public double ActWintime { get; set; }
        }
    }



**Program Class**



 static void CallMain()
    {
        _client = new MongoClient();
        _database = _client.GetDatabase("CaptureEmployee");



        var collectionGet = _database.GetCollection<ActiveWin>("ActiveWindow");
        var filter = new BsonDocument();
        var result = collectionGet.Find(filter).ToList();

    }

当我从MongoDB集合中检索数据时，此结果列表中的ActiveDate显示为“0001-01-01 12:00:00”，非常有价值。我如何从数据库中获得正确的DateTime？
