C# 操作MongoDB存在的问题及解决方案

Find简单实例

 Category category=null;
 var database = MongoContext.MONGO_CLIENT.GetDatabase("customers");
 var collection = database.GetCollection<BsonDocument>("category");
 FilterDefinition<BsonDocument> filters = MongoContext.FILTER.Eq("CustomerID", customerID);
 BsonDocument bsons = collection.Find(filters).FirstOrDefault();
 if (bsons != null)
 {
 	string json = bsons.ToJson();
 	category = BsonSerializer.Deserialize<Category>(bsons.ToJson());
}

1、ObjectId _id属性反序列化解决方案

  	[BsonIgnoreExtraElements]
    public class Category
    {
        public Category()
        {
            _id = ObjectId.GenerateNewId();
        }
        public ObjectId _id { get; set; }
    }

2、DateTime类型的数据序列化时间有时区问题解决方案

    [BsonDateTimeOptions(Kind = DateTimeKind.Local)]
    public DateTime? TagTime { get; set; }
