问题描述
有人有没有使用NORM(C#)在MongoDB中查询嵌套/内部对象的示例?例如,如果集合中的典型文档看起来像Order/OrderItems,那么如何通过OrderItem.Quantity> 10查找特定的OrderItem.
Does anyone have a sample of how to query for nested/inner objects in MongoDB using NORM (C#)? For example, if a typical document in a collection looks like Order/OrderItems, how can I look up a specific OrderItem by OrderItem.Quantity > 10.
推荐答案您需要创建额外的字段'size',添加新项目并对其进行查询时会增加该字段.
You need to create extra field 'size', that you increment when add new items, and query on it.
