The following example demonstrates how to remove a locked item from the cache. First create a CacheItem.
 Copy imageCopy
Cache theCache = NCache.InitializeCache("myreplicatedcache");
Add an item in the cache.
 Copy imageCopy
theCache.Add("cachedItemKey", new "cachedItemValue");
Create the CacheItemVersion.
 Copy imageCopy
CacheItemVersion version = new CacheItemVersion();
Get the added item from cache and get the item version.
 Copy imageCopy
object cachedItem = theCache.Get("cachedItemKey", DSReadOption.None, ref version);
if (cachedItem != null)
        //Now remove the cached item using version acquired earlier.
        object removedItem = theCache.Remove("cachedItemKey", version);
    catch (OperationFailedException ex)
        //Do something
