首先下載windows平臺下的memcached，然後安裝。安裝完之後就是啟動memcached服務了，你可以在cmd下用dos命令輸入，也可以在計算機管理->服務->memcached->啟動.來開啟服務.
隨後就是在項目中引入相關dll：
Commons.dll，ICSharpCode.SharpZipLib.dll，log4net.dll，Memcached.ClientLibrary.dll
在項目的引用中引入Memcached.ClientLibrary.dll
隨後就是編寫程序了，在這裏創建一個MVC程序:
在Models文件夾中創建一個類:
| 1 2 3 4 5 6 7 8 9 10 11 12 13 |
[Serializable]
public class VIP
{
public string UserName { get; set; }
public int? Vip { get; set; }
public DateTime? VipEndDate { get; set; }
public string Mail { get; set; }
public string QQ { get; set; }
}
|
若沒有標註為可序列化，則後續運行程序將會報錯。
隨後創建一個MemcachedHelper類來輔助編程.
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 |
public class MemcachedHelper
{
public static MemcachedClient mclient;
static MemcachedHelper()
{
string[] serverlist = new string[] { "127.0.0.1:11211" };
SockIOPool pool = SockIOPool.GetInstance("First");
pool.SetServers(serverlist);
pool.Initialize();
mclient = new MemcachedClient();
mclient.PoolName = "First";
mclient.EnableCompression = false;
}
public static bool set(string key, object value, DateTime expiry)
{
return mclient.Set(key, value, expiry);
}
public static object Get(string key)
{
return mclient.Get(key);
}
}

最後就是Controller裏面的具體實現:
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 |
public class EntityMemcachedController : Controller
{
//
// GET: /EntityMemcached/
/// <summary>
/// 序列化實體類為字節數組，將其存儲到Memcached中，以緩存數據，從而減輕訪問壓力....
/// </summary>
/// <returns></returns>
public ActionResult Index()
{
var vipInfo = new List<VIP>{
new VIP{ UserName="張三", Vip=1, QQ="3123456", Mail="3123456", VipEndDate=(DateTime?)DateTime.Now.AddDays(1) },
new VIP{ UserName="李四", Vip=1, QQ="4123456", Mail="4123456", VipEndDate=(DateTime?)DateTime.Now.AddDays(2) },
new VIP{ UserName="王五", Vip=1, QQ="5123456", Mail="5123456", VipEndDate=(DateTime?)DateTime.Now.AddDays(3) },
new VIP{ UserName="趙六", Vip=1, QQ="6123456", Mail="6123456", VipEndDate=(DateTime?)DateTime.Now.AddDays(4) },
new VIP{ UserName="劉七", Vip=1, QQ="7123456", Mail="7123456", VipEndDate=(DateTime?)DateTime.Now.AddDays(5) }
};
if (Request.Cookies["_EntityMemcached"] == null)
{
string sessionId = Guid.NewGuid().ToString();
Response.Cookies["_EntityMemcached"].Value = sessionId;
Response.Cookies["_EntityMemcached"].Expires = DateTime.Now.AddMinutes(1);//設置cookie過期時間
MemcachedHelper.set(sessionId, vipInfo, DateTime.Now.AddMinutes(1));//設置緩存過期時間
return Content("Memcached分布式緩存設置成功！！！");
}
else
{
string key = Request.Cookies["_EntityMemcached"].Value.ToString();
object obj = MemcachedHelper.Get(key);
List<VIP> info = obj as List<VIP>;
if (info != null)
{
return View(info);
}
}
return Content("若顯示則有‘bug‘");
}
