- percent
- Int32
The percentage of total cache entries to remove.
Returns
The number of entries removed from the cache.
Remarks
The Trim property first removes entries that have exceeded either an absolute or sliding expiration. Any callbacks that are registered for items that are removed will be passed a removed reason of Expired.
If removing expired entries is insufficient to reach the specified trim percentage, additional entries will be removed from the cache based on a least-recently used (LRU) algorithm until the requested trim percentage is reached. Any callbacks that are registered for items that are removed this way will be passed a remove reason of Evicted.
