接下来开始写程序，老规矩，直接上代码：

    public class Memcached : ICache
    {
        private static readonly MemcachedClient CacheClient = new MemcachedClient();
        
        /// <summary>
        /// 获取缓存

        /// <typeparam name="T"></typeparam>
        /// <param name="cacheKey"></param>
        /// <returns></returns>
        public T GetCache<T>(string cacheKey) where T : class
        {
            try
            {
                return (T)CacheClient.Get(cacheKey);
            }
            catch
            {
                return default(T);
            }
        }

        /// <summary>

        public void WriteCache<T>(T value, string cacheKey) where T : class
        {
            //CacheClient.Store(StoreMode.Set, cacheKey, value);

            CacheClient.Store(Exists(cacheKey) ? StoreMode.Set : StoreMode.Replace, cacheKey, value, DateTimeHelper.Now.AddMinutes(10));
        }
