下面的图比较形象.
同样它也是扩平台的,今天我们来看windows下的服务端以及使用.net的客户端访问它.我们
选择了Enyim Memcached这个客户端.
首先,我们安装windows版的服务端,你可以从这个站点下载. 安装时使用命令行:
memcached.exe –d install
memcached.exe -d start
该命令启动 Memcached，默认监听端口为 11211
memcached.exe -p 端口号 自行设置监听端口
这样将Windows service中创建一个memcached的服务. 同样你可以使用 –d uninstall 来卸载它. 运行时将默认监听11211
IP:127.0.0.1,如下图所示:
接着创建一个控制台程序引用Enyim.Caching.dll, 并在配置文件:
1: <configuration>
2: <configSections>
3: <sectionGroup name="enyim.com">
4: <section name="memcached" type="Enyim.Caching.Configuration.MemcachedClientSection, Enyim.Caching"/>
5: </sectionGroup>
6: </configSections>
7: <enyim.com>
8: <memcached protocol="Binary">
9: <servers>
10: <add address="127.0.0.1" port="11211"/>
11: </servers>
12: </memcached>
13: </enyim.com>
14: </configuration>
测试一下:
1: using (var mc = new MemcachedClient())
2: {
3: mc.Store(StoreMode.Set, "mytime", DateTime.Now.ToString());
4: string temp = mc.Get<string>("mytime");
5:
6: Console.Write(temp);
7: Console.Read();
8: }
示例2：
配置config文件
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
</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);
}
}
}
}
