Memcached 可视化界面 TreeSoft   TreeNMS 。由于他是使用java语言写的，所以当我们存入C#的值进去，会被序列化成对象，无法查看他的值。

1、Redis和Memcached的配置不能同时存在app.config中 否者会报错，找不到 RedisConfig

2、App.config

3、 使用Nuget 添加相关的包：EnyimMemcached 

 

MemcachedHelper:

using Enyim.Caching;
using System;
using System.Collections.Generic;
using System.Linq;
using Enyim.Caching.Memcached;
using System.Text;

namespace TestMemcached
{
   
    /// 

    /// MemcachedClient 帮组类 对外提供接口方法
    /// 
    public class MemcachedHelper
    {
        private static MemcachedClient MemClient;
        static readonly object padlock = new object();

        //线程安全的单例模式
        public static MemcachedClient getInstance()
        {
            if (MemClient == null)
            {
                lock (padlock)
                {
                    if (MemClient == null)
                    {
                        try
                        {
                            MemClient = new MemcachedClient();//app.config中存在默认配置部分 ,所以不需要去找IP和Port
                          //  MemClient = new MemcachedClient("enyim.com/memcached");
                        }
                        catch (Exception ex)
                        {
                            throw ex;
                        }
                    }
                }
            }
            return MemClient;
        }

        /// 

        /// 删除指定缓存

        public static bool Remove(string key)
        {
            MemcachedClient mc = getInstance();

            return mc.Remove(key);
        }

        ///

        {

            mc.FlushAll();
        }
          #region 存取值 
        ///

        public static object Get(string key)
        {
            if (key == null || key.Trim() == "") return null;
            MemcachedClient mc = getInstance();
           
            return mc.Get(key);
        }

        public static bool Set(string key, object value)
        {
            if (key == null || key.Trim() == "") return false;
            MemcachedClient mc = getInstance();
            var data = mc.Get(key);
            
            if (data == null)
                return mc.Store(StoreMode.Add, key, value);
            else
                return mc.Store(StoreMode.Replace, key, value);
        }
        public static bool Set(string key, T value)
        {
            if (key == null || key.Trim() == "") return false;
            MemcachedClient mc = getInstance();
            var data = mc.Get(key);
            if (data == null)
               //如果返回false 可以查看我的另外一篇文章 专门讲解了这个错误  坑
                return mc.Store(StoreMode.Add, key, value, new TimeSpan(0, 5, 0));
            else
                return mc.Store(StoreMode.Replace, key, value);
        }
        public static bool Set(string key, T value,TimeSpan timeSpan)
        {
            if (key == null || key.Trim() == "") return false;
            MemcachedClient mc = getInstance();
            var data = mc.Get(key);
            if (data == null)
                return mc.Store(StoreMode.Add, key, value, timeSpan);
            else

        {
           
            MemcachedClient mc = getInstance();
            return mc.Get(key);
        }
        #endregion

    }
}

3、在 Programma中获取值。我测试了多种数据类型的存取。供参考

namespace TestMemcached
{
    class Program
    {
        static void Main(string[] args)
        {
            // 程序调用 groupName用来区分不同的服务或应用场景
            // MemcachedHelper.SetValue( "1","sun", "ting", DateTime.Now.AddMinutes(5));
            //var restr = MemcachedHelper.GetValue("1", "sun");
            // var obj = MemcachedHelper.GetValue(groupName, "p001");


            // MemcachedHelper.Set( "1","sun");
            var restr = MemcachedHelper.Get("1");

            // User u = new User();
            // u.name = "sun";
            // u.sex = "gril";
            //string str =  Newtonsoft.Json.JsonConvert.SerializeObject(u);
            // bool isok=   MemcachedHelper.Set("user",str);
            // string restr = MemcachedHelper.Get("user").ToString();
            // User user =Newtonsoft.Json.JsonConvert.DeserializeObject(restr);
            // Console.WriteLine(user);

            List list = new List();
            list.Add("as1");
            list.Add("as2");
            list.Add("as3");
            //List list = new List();
            //list.Add(1);
            //list.Add(1);
            //list.Add(1);
            //list.Add(1);


            //bool isok = MemcachedHelper.Set>("list", list);
            //List list2 = MemcachedHelper.Get>("list");
            //Console.WriteLine(list2);


            //var s = MemcachedHelper.Get("list");
            //List list2 = new List(s.ToString().Split(','));
            //Console.WriteLine(list2);

            //User u = new User();
            //u.name = "sun";
            //u.sex = "gril";
            //bool isok = MemcachedHelper.Set("user",u);
            //User us=  MemcachedHelper.Get("user");
            //Console.WriteLine(us);
            //float[] a = new float[] { 2,1,4};
            //bool isok2=  MemcachedHelper.Set("a",a);
            //var aa=     MemcachedHelper.Get("a");
            //Console.WriteLine(aa);

            User u = new User();
            u.name = "sun";
            u.sex = "gril";
            List users = new List();
            users.Add(u);
            users.Add(u);

            //bool isok3 = MemcachedHelper.Set>("users", users);
            //List list3 = MemcachedHelper.Get>("users");
            //Console.WriteLine(list3);
            bool isok3 = MemcachedHelper.Set("users", users);
            List list3 = MemcachedHelper.Get>("users");

            bool isok4 = MemcachedHelper.Set("qw", 1234434);
            bool isok5=  MemcachedHelper.Set("as4", "sun4");
            Console.WriteLine(list3);
        }


    }
    [Serializable]
    class User
    {
        public string name;
        public string sex;

    }
