Items can be retrieved from the cache either by using a Get method or the cache indexer. Both of the methods are explained below with examples.
Include the following namespace in your project:
using Alachisoft.NCache.Web.Caching;
Using Get Method
Here is how you can retrieve items from the cache.
Cache _cache = NCache.Caches["mycache"];
// Returns null if item not found
object myObject = _cache.Get("Customer:David:1001");
if (myObject == null)
{
// Item not found
}
Using Cache["key"]
Here is another way to retrieve items from the cache.
Cache _cache = NCache.Caches["mycache"];
// Returns null if item not found
object myObject = _cache["Customer:David:1001"];
if (myObject == null)
{
// Item not found
}
Using Contains Method
You can also check whether an item exists in the cache or not.
Cache _cache = NCache.Caches["mycache"];
// Returns true or false
if (_cache.Contains("Customer:David:1001") == false)
{
// Item not found
}
