Memcached 简单应用

需要引用的 log4net.dll，Memcached.ClientLibrary.dll

添加类MemcachedTools.cs

代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Memcached.ClientLibrary;
using System.Collections;
using System.Threading;

/// <summary>
///MemcachedTools 的摘要说明
/// </summary>
public class MemcachedTools
{
      //  <add key="newsMemcache" value="127.0.0.1:11211" />
    //<add key="hqMemecache" value="172.28.1.27:11211" />

    static MemcachedTools()
    {
        String[] serverlist = {"127.0.0.1:11211"};
        SockIOPool pool = SockIOPool.GetInstance("news");
        pool.SetServers(serverlist);
        pool.Initialize();
    }

 
    /// <summary>
    ///
    /// </summary>
    private static MemcachedClient NewsClient
    {
        get
        {
            MemcachedClient mc = new MemcachedClient();
            mc.PoolName = "news";
            mc.EnableCompression = false;
            return mc;
        }
    }

    /// <summary>
    /// 添加一个缓存
    /// </summary>
    /// <param name="obj">缓存对象</param>
    /// <param name="sj">缓存时间</param>
    public static void Add(string key, object obj, DateTime expiry)
    {
        if (!NewsClient.Add(key, obj, expiry))
        {
            NewsClient.Set(key, obj, expiry);
        }
    }

    public static object GetHangqing(string key)
    {
        object obj = NewsClient.Get(key);
        return obj;
    }

    public static string GetHangqingStr(string key)
    {
        string data = (string)NewsClient.Get(key);
      
        return data;
    }

    public static object[] GetHangqing(string[] keys)
    {
        object[] objs = NewsClient.GetMultipleArray(keys);
        return objs;
    }

    public static Hashtable GetHangqingHash(string[] keys)
    {
        Hashtable ht = NewsClient.GetMultiple(keys);
      
        return ht;
    }
}

页面方法引用：

       //linq读取json格式
        public string Dbval()
        {
           
            StringBuilder Json = new StringBuilder();
            //var Myjson={"bindings"};
            foreach (Service_help_special c in dcont.Service_help_special)
            {
                Json.Append("{specialid:" + c.specialid + ",content:" + c.content + ",infotitle:"+ c.infotitle +",infoid:"+ c.infoId +"}");
               //mstring.Append(c.specialid + ":" + c.content + "," + c.infotitle + "," + c.infoId + "&");
            }
            return Json.ToString();
        }
        //添加内容到Memcache
        protected void Button1_Click(object sender, EventArgs e)
        {
            MemcachedTools.Add("bb",Dbval(), DateTime.Now.AddHours(10));
            Label1.Text = "";
        }
        //读取名称 为“bb”的Memcache
        protected void Button2_Click(object sender, EventArgs e)
        {
            Label1.Text = MemcachedTools.GetHangqingStr("bb");
        }
