Problem to find all cache keys our memory by using Memcached

Question

Hi Friends,

I am using Memcached for implementing distributed cache. The Library that i used for it is Enyim.Caching. With the help of its great documents I've furnished all my requirements. But i am not be able to find all cache key in the memory. With the help of System.Web.Caching i am doing for the same requirement as.

   #region Gets the cache keys.
    /// <summary>
    /// Gets the cache keys.
    /// </summary>
    /// <returns></returns>
    public override List<string> GetCacheKeys()
    {
        //ToDo:To be implemented
        List<string> keys = new List<string>();

        IDictionaryEnumerator ca = _cache.GetEnumerator();
        while (ca.MoveNext())
        {
            keys.Add(ca.Key.ToString());
        }
        return keys;
    }
    #endregion

Please provide me appropriate solutions to fulfill my requirements.

i will be very thankful to you all.
