Examples

The following example demonstrates how to assign an item high priority when you insert it into your application's Cache object.

Note: For more information about how to use this method with the CacheItemRemovedCallback delegate, see CacheItemRemovedCallback.

First create CacheItems.
CopyC#
string[] keys = {"SQLDSN", "ORADSN"};
CacheItem items[] = new CacheItem[2];
items[0] = new CacheItem(sqlConnectionString);
item.AbsoluteExpiration = DateTime.Now.AddMinutes(2);
item.SlidingExpiration = TimeSpan.Zero;
item.Priority = CacheItemPriority.High;
item.ItemRemoveCallback = onRemove;

items[1] = new CacheItem(oraConnectionString);
item.AbsoluteExpiration = DateTime.Now.AddMinutes(1);
item.SlidingExpiration = TimeSpan.Zero;
item.Priority = CacheItemPriority.Low;
item.ItemRemoveCallback = onRemove;
 Then insert CacheItems to the cache
CopyC#
NCache.Cache.Insert(keys, items, "Connection", null);
 Or simply in a class deriving from [!:Alachisoft.NCache.Web.UI.NPage] or [!:Alachisoft.NCache.Web.UI.NUserControl].
CopyC#
Cache.Insert(keys, items, "Connection", null);
