Examples

The following example demonstrates how to add items to the cache with an absolute expiration 2 minutes from now, 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 = {"First", "Second"};
CacheItem items = new CacheItem[2]
items[0] = new CacheItem(firstTimeStamp);
items[0].AbsoluteExpiration = DateTime.Now.AddMinutes(2);
items[0].Priority = CacheItemPriority.High;
items[0].ItemRemoveCallback = onRemove;

items[1] = new CacheItem(secondTimeStamp);
items[1].AbsoluteExpiration = DateTime.Now.AddMinutes(2);
items[1].Priority = CacheItemPriority.Low;
items[1].ItemRemoveCallback = onRemove;
Then add CacheItem to the cache
 Copy imageCopy
OnDataSourceItemAdded(IDictionary result)
{
...
}
Cache cache = NCache.InitializeCache("myCache");
   cache.Add(keys, items, DSWriteOption.WriteBehind, new DataSourceItemsAddedCallback(OnDataSourceItemAdded));
