Memcached的.NET客户端(一)【.NET Memcached Client Library使用】

下载客户端的3个dll,

ICSharpCode.SharpZipLib.dll,log4net.dll,Memcached.ClientLibrary.dll

新建一个简单控制台应用程序:

class Program
    {
        private static void Main(string[] args)
        {
            SockIOPool pool = SockIOPool.GetInstance();
            string[] servers = {"127.0.0.1:11211"};
            pool.SetServers(servers);
            pool.MinConnections = 3;
            pool.MaxConnections = 5;
            pool.InitConnections = 3;
            pool.SocketConnectTimeout = 5000;
            pool.Initialize();

            MemcachedClient client = new MemcachedClient();
            
            client.EnableCompression = false;
            Console.WriteLine("-----------------------Memcached Set 设置值--------------------------");
            client.Set("key1", "value1");
            Console.WriteLine(client.Get("key1"));
            Console.WriteLine("-----------------------Memcached Add 设置值--------------------------");
            client.Add("key2", "value2");
            Console.WriteLine(client.Get("key2"));
            client.Set("key2", "value1 value2");
            Console.WriteLine(client.Get("key2"));
            Console.WriteLine("-----------------------Memcached Replace 设置值--------------------------");
            client.Replace("key2", "value3");
            Console.WriteLine(client.Get("key2"));

            Console.WriteLine("-----------------------Memcached 键值是否存在--------------------------");
            if (client.KeyExists("key2"))
            {
                Console.WriteLine("键key2 存在");
            }
            if (client.KeyExists("hechen") == false)
            {
                Console.WriteLine("键hechen 不存在");
            }

            Console.WriteLine("-----------------------Memcached 删除数据--------------------------");
            client.Add("key4", "value4");
            Console.WriteLine("key4==>" + client.Get("key4"));
            client.Delete("key4");
            if (!client.KeyExists("key4"))
            {
                Console.WriteLine("key4 已将删除");
            }

            Console.WriteLine("-----------------------Memcached 数据过期--------------------------");
            client.Add("key5", "value5", DateTime.Now.AddMilliseconds(5000));
            Console.WriteLine(client.Get("key5"));
            System.Threading.Thread.Sleep(6000);
            Console.WriteLine("过期: " + client.Get("key5"));
             

            //自定义实例化封装,接口
            ICache cache = Memcache.Instance();
            Console.WriteLine(cache.ContainKey("hechen"));
            Student student = new Student() {ID = 1, Name = "hechen"};
            Console.WriteLine(cache.Add<Student>("hechen", student));
            Console.WriteLine(cache.ContainKey("hechen"));
            Student stu = cache.Get<Student>("hechen");
            Console.WriteLine(stu.ID + ":" + stu.Name);
            cache.Add("qa", "ddddddddd");
            cache.Remove();
            Student stu1 = cache.Get<Student>("hechen");
            if (stu1 != null)
            {
                Console.WriteLine(stu1.ID + ":" + stu1.Name);
            }
            Console.WriteLine(cache.Get("qa"));


        }
    }
自定义实例化的接口ICache.cs代码:

 public interface ICache
    {
        bool ContainKey(string argKey);

        bool Add(string argKey,object argValue);

        bool Add(string argKey, object argValue, DateTime argDateExpiration);

        bool Add<T>(string argKey, T entity) where T : class;

        bool Add<T>(string argKey, T entity, DateTime argDateExpiration) where T : class;

        bool Set(string argKey, object argValue);

        bool Set(string argKey, object argValue, DateTime argDateExpiration);

        bool Set<T>(string argKey, T entity) where T : class;

        bool Set<T>(string argKey, T entity, DateTime argDateExpiration) where T : class;

        bool Replace(string argKey,object argValue);

        bool Replace(string argKey,object argValue,DateTime argDateExpiration);

        bool Replace<T>(string argKey, T entity) where T : class;

        bool Replace<T>(string argKey, T entity, DateTime argDateExpiration) where T : class;

        object Get(string argKey);

        T Get<T>(string argKey);

        bool Remove(string argKey);

        bool Remove(string argKey, DateTime argDateExpiration);

        bool Remove();

        bool Remove(ArrayList servers);

    }
Memcache.cs代码如下:

 public class Memcache:ICache
    {
        private MemcachedClient client;
        private static Memcache memcache;

        /// <summary>

            string[] servers = { "127.0.0.1:11211" };
            pool.SetServers(servers);
            pool.MinConnections = 3;
            pool.MaxConnections = 5;
            pool.InitConnections = 3;
            pool.SocketConnectTimeout = 5000;
            pool.Initialize();
            this.client = new MemcachedClient();
            client.EnableCompression = false;
        }

        public static Memcache Instance()
