The following example demonstrates how to add an item to the cache with an absolute expiration of 2 minutes from now, a priority of high, and that notifies the application when the item is removed from the cache. First create a CacheItem.
CopyC#
object someData = new object();
CacheItem item = new CacheItem(someData);
item.AbsoluteExpiration = DateTime.Now.AddMinutes(2);
item.Priority = CacheItemPriority.High;
item.ItemRemoveCallback = onRemove;
 Then add CacheItem to the cache
CopyC#
OnDataSourceItemAdded(IDictionary result)
{
...
}
Cache cache = NCache.InitializeCache("myCache");
   cache.Add("someData", item);
