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.Priority = CacheItemPriority.High; item.ItemRemoveCallback = onRemove; items[1] = new CacheItem(oraConnectionString); item.AbsoluteExpiration = DateTime.Now.AddMinutes(1); item.Priority = CacheItemPriority.Low; item.ItemRemoveCallback = onRemove;
CopyC#
Cache cache = NCache.InitializeCache("myCache"); string[] keys = new string[]{"myItem1", "myItem2"}; CacheItem[] items = new CacheItem[]{myItem1, myItem2}; cache.InsertBulk(keys, items, DSWriteOption.WriteThru, new DataSourceItemsUpdatedCallback(onDSItemsUpdated));
