c# - CacheItem regionName 属性责任/用途？

Question

MSDN 文档没有详细解释它的用途。

由于它是可选的，我几乎假设它类似于某种元数据。

我现在如何看待它，我想用它来为特定用户指定缓存，例如:

new CacheItem(key: "keyName", value: objectData, regionName: "userName")

CacheItem 类的 regionName 属性的职责是什么？它有什么用？

The custom class demonstrates how you would store the cached data in anamed region in memory. The built-in memory cache object does notsupport the concept of regions but it is used in this blog todemonstrate how you would implement regions in a custom cache class.A cache region is a partition in memory that is reserved for storingone or more cache objects. A cache region helps organize cache objectsin memory.
