C# 使用memcached-null-ICode联盟

1. 下载memcache(http://jehiah.cz/projects/memcached-win32)的windows稳定版http://jehiah.cz/projects/memcached-win32/files/memcached-1.2.1-win32.zip

2. 解压，把memcached.exe 放到c:windowssystem32目录下，然后打开命令行窗口输入下面命令

cd windowssystem32

memcached.exe -d install

memcached.exe -d start 该命令启动 Memcached，默认监听端口为 11211

3. 下载 Memcached Client http://enyimmemcached.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=13095

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>
            <servers>
                
                <add address="127.0.0.1" port="11211" />

            </servers>
            <socketPool minPoolSize="10" maxPoolSize="100" connectionTimeout="00:00:10" deadTimeout="00:02:00" />
        </memcached>
    </enyim.com>
    <memcached keyTransformer="Enyim.Caching.TigerHashTransformer, Enyim.Caching">
        <servers>
            <add address="127.0.0.1" port="11211" />

        </servers>
        <socketPool minPoolSize="2" maxPoolSize="100" connectionTimeout="00:00:10" deadTimeout="00:02:00" />
    </memcached>
</configuration>
这里的port:11211是, memcached-1.2.1-win32在安装时默认使用的port.当然你可以用memcached.exe -p 端口号来自行设置。

第二步，新建TestMemcachedApp的console project

引用Enyim.Caching.dll

基础代码如下：

//create a instance of MemcachedClient
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"));

完整代码如下，

using System;
using System.Collections.Generic;
using System.Text;
using Enyim.Caching;
using Enyim.Caching.Memcached;
using System.Net;
using Enyim.Caching.Configuration;

namespace DemoApp
{
    class Program
    {
        static void Main(string[] args)
        {
            // create a MemcachedClient
            // in your application you can cache the client in a static variable or just recreate it every time
            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();
}

        // objects must be serializable to be able to store them in the cache
        [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);
            }
        }
    }
}
