Examples
The following example demonstrates how to add items to the cache with an absolute
expiration defined by a variable d, a sliding expiration defined by a variable t, a priority of
high, and that notifies the application when the item is removed from the cache.
First create a CacheItems.
Then add CacheItem to the cache
CopyC#
string keys = {"ORD_23", "ORD_67"}; CacheItem items = new CacheItem[2] items[0] = new CacheItem(new Order()); items[0].AbsoluteExpiration = d; items[0].SlidingExpiration = t; items[0].Priority = CacheItemPriority.High; items[0].ItemRemoveCallback = onRemove; items[1] = new CacheItem(new Order()); items[1].AbsoluteExpiration = d; items[1].SlidingExpiration = t; items[1].Priority = CacheItemPriority.Low; items[1].ItemRemoveCallback = onRemove;
CopyC#
NCache.Cache.Add(keys, items, "Customer", "Orders"); Cache.Add(keys, items, "Customer", "Orders");
