.Net Memcached缓存用法

memcached是一个以key-value的形式缓存数据的缓存系统。通过将数据缓存到内存中，从而提高数据的获取速度。
memcached以key-value的形式来保存数据，你可以为你每一段数据关联一个key，然后以后可以通过这个key获取
这段数据。

memcached是一个库还是什么？memcached其实是一个单独的网络服务器程序。它的网络底层基于libevent，你可以
将其运行在网络中的一台服务器上，通过网络，在遵循memcached的协议的基础上与memcached服务器进行通信。

一、安装Memcached服务
1. copy to c:\
2. start -> run -> cmd
3.
C:\memcached -d install -m 500
C:\memcached -d start

二、引用Enyim.Caching.dll

三、配置Config文件

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="enyim.com">
      <section name="memcached" type="Enyim.Caching.Configuration.MemcachedClientSection, Enyim.Caching"/>
    </sectionGroup>
    <section name="memcached" type="Enyim.Caching.Configuration.MemcachedClientSection, Enyim.Caching"/>
  </configSections>

  <enyim.com>
    <memcached configSource="ConfigFiles\enyim.com.config"/>
  </enyim.com>
  <memcached configSource="ConfigFiles\memcached.config"/>
  
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
</configuration>

enyim.com.config

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
    <!-- 
        Please read the documentation first:
            http://github.com/enyim/EnyimMemcached/wiki/MemcachedClient-Configuration

        Use this section as a template if you're connecting to regular memcached servers.
        Note: you must have the enyim.com/memcached section if you're using the parameterless constructor of EnyimMemcachedClient.
      -->
    <memcached protocol="Text">
        <servers>
            <add address="127.0.0.1" port="11211" />
        </servers>
        <socketPool minPoolSize="50" 
                    maxPoolSize="1000" 
                    connectionTimeout="00:01:10" 
                    deadTimeout="00:02:00" 
                    />
    </memcached>

memcached.config

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<memcached keyTransformer="Enyim.Caching.TigerHashTransformer, Enyim.Caching">
    <servers>
        <add address="127.0.0.1" port="11211" />
    </servers>
    <socketPool minPoolSize="50" maxPoolSize="1000" connectionTimeout="00:01:10" deadTimeout="00:02:00" />
</memcached>

四、实例代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Enyim.Caching.Configuration;
using Enyim.Caching;
using Enyim.Caching.Memcached;


namespace MemcachedConsole
{
    class Program
    {
        static void Main(string[] args)
        {
            MemcachedClient mc = new MemcachedClient();

            // store a string in the cache
            mc.Store(StoreMode.Set, "MyKey", "Hello World");
            // retrieve the item from the cache
            Console.WriteLine(mc.Get("MyKey"));
            // store some other items
            mc.Store(StoreMode.Set, "D1", 1234L);
            mc.Store(StoreMode.Set, "D2", DateTime.Now);
            mc.Store(StoreMode.Set, "D3", true);
            mc.Store(StoreMode.Set, "D4", new Product());
            mc.Store(StoreMode.Set, "D5", new byte[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 });
            Console.WriteLine("D1: {0}", mc.Get("D1"));
            Console.WriteLine("D2: {0}", mc.Get("D2"));
            Console.WriteLine("D3: {0}", mc.Get("D3"));
            Console.WriteLine("D4: {0}", mc.Get("D4"));

            byte[] tmp = mc.Get<byte[]>("D5");
            // delete them from the cache
            mc.Remove("D1");
            mc.Remove("D2");
            mc.Remove("D3");
            mc.Remove("D4");
            // add an item which is valid for 10 mins
            mc.Store(StoreMode.Set, "D4", new Product(), new TimeSpan(0, 10, 0));
            Console.ReadLine();
        }
    }

    [Serializable]
    class Product
    {
        public double Price = 1.24;
        public string Name = "Mineral Water";
        public override string ToString()
        {
            return String.Format("Product {{{0}: {1}}}", this.Name, this.Price);
        }
    }
}
