CacheItemPriority Enumeration

.NET Framework 4.5

.NET Framework 4

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

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)

Syntax

C++

Copy


public enum CacheItemPriority

Members

	Member name	Description
	Default	Indicates that there is no priority for removing the cache entry.
	NotRemovable	Indicates that a cache entry should never be removed from the cache.

Remarks

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

Important
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.
