CacheItemPriority Enumeration

Specifies a priority setting that is used to decide whether to evict a cache entry.

Namespace:  System.Runtime.Caching
Assembly:  System.Runtime.Caching (in System.Runtime.Caching.dll)

public enum CacheItemPriority

Member nameDescription
DefaultIndicates that there is no priority for removing the cache entry.
NotRemovableIndicates that a cache entry should never be removed from the cache.

The only priority that can be set is whether an entry should remain in the cache forever.

Important noteImportant

Adding an entry to the cache with a priority level of NotRemovable has the potential to overflow the cache with entries that can never be removed. Cache implementations should only set the NotRemovable priority for a cache entry if they provide ways to evict such entries from the cache and to manage the number of cache entries.
