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.
 Copy imageCopy
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;
Then add CacheItem to the cache
 Copy imageCopy
NCache.Cache.Add(keys, items, "Customer", "Orders");

Cache.Add(keys, items, "Customer", "Orders");
