推荐答案

内存中的集合就是这样：一组对象保存在内存中，而不是通过硬盘文件，数据库服务器或类似文件访问。

所有标准C＃集合都在内存中：List< T>，Queue< T>，Stack< T>，DataTable，DataSet，甚至ArrayList和数组都是内存中的集合。 DataReader不是：它保存在服务器上并逐行获取（缓冲除外）。

An in-memory collection is just that: a collection of objects that is kept in memory, rather than being accessed via a hard disk file, or a DB server, or similar.
All of the standard C# collections are in-memory: List<T>, Queue<T>, Stack<T>, DataTable, DataSet, even ArrayList and arrays are all in-memory collections. DataReader isn't: it's held at the Server and fetched row-by-row (buffering excepted).
