MemoryCache.Trim Method

Removes a specified percentage of cache entries from the cache object.

Namespace:  System.Runtime.Caching
Assembly:  System.Runtime.Caching (in System.Runtime.Caching.dll)
public long Trim(
	int percent
)

Parameters

percent
Type: System.Int32

The percentage of total cache entries to remove.

Return Value

Type: System.Int64
The number of entries removed from the cache.

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.
