ASP.Net AppFabric Cache missing Flush/Clear and Count/GetCount methods?

Question

I am trying to convert a solution using EntLib into using AppFabric caching. By help of a few extension methods this is a fairly pain-free process.

Answer 1

See my previous answer for my speculation as to how the cache works internally when you don't specify a region, and how you can get the count of objects that aren't in a named region.

We can build a Flush method using the same technique:

public void Flush (this DataCache cache)
{
    foreach (string regionName in cache.GetSystemRegions()) 
    {     
        cache.ClearRegion(regionName) 
    } 
}

As I said there, I think named regions are probably the way to go - it seems to me that using them solves more problems than it creates.

If anyone will have problems in future (like me) - here is the full code for clearing cache.

private static DataCacheFactory _factory;
        private const String serverName = "<machineName>";
        private const String cacheName = "<cacheName>";

        static void Main(string[] args)
        {
            Dictionary<String, Int32> cacheHostsAndPorts = new Dictionary<String, Int32> { { serverName, 22233 } };
            Initialize(cacheHostsAndPorts);
            DataCache cache = _factory.GetCache(cacheName);
            FlushCache(cache); 
            Console.WriteLine("Done");
            Console.ReadLine();
        }

        private static void FlushCache(DataCache cache)
        {
            foreach (string regionName in cache.GetSystemRegions())
            {
                cache.ClearRegion(regionName);
            }
        }

        public static void Initialize(Dictionary<String, Int32> cacheHostsAndPorts)
        {
            var factoryConfig = new DataCacheFactoryConfiguration
            {
                Servers = cacheHostsAndPorts.Select(cacheEndpoint => new DataCacheServerEndpoint(cacheEndpoint.Key, cacheEndpoint.Value))
            };

            _factory = new DataCacheFactory(factoryConfig);
        }
