mongoDB 官方C#驱动 序列化数组但序列成System.Collections.Generic.List`1解决方法

   [Serializable]    public class ActionClass    {        [BsonId(IdGenerator = typeof(StringObjectIdGenerator))]        public string ID { get; set; }        public string Content { get; set; }        public string[] Tag { get; set; }     }

        public static string Insert(ActionClass row)        {            SafeModeResult rtn = DB.GetCollection(TableName).Insert<ActionClass>(row);            return row.ID;        }
