CacheItemUpdateReason Enumeration

Specifies the reason that a cached item is being removed from the Cache object.

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

public enum CacheItemUpdateReason

Member nameDescription
ExpiredSpecifies that the item is being removed from the cache because the absolute or sliding expiration interval expired.
DependencyChangedSpecifies that the item is being removed from the cache because the associated CacheDependency object changed.

Unlike the CacheItemRemovedReason enumeration, this enumeration does not include the Removed or Underused values. Updateable cache items are not removable and can thus never be automatically removed by ASP.NET even if there is a need to free memory.
