1、使用VS2010开发,首先下载C#下用到的redis的dll,免费版的,下载链接如下
https://download.csdn.net/download/chencaw/10472019
2、创建一个Redis操作的公用类RedisCacheHelper
using System.Collections.Generic;
using System.Configuration;
using System.Linq;
using System.Text;
using System.Web;
//using ServiceStack.Common.Extensions;
using ServiceStack.Redis;
using ServiceStack.Logging;
namespace chenredis1.RedisHelper
{
class RedisCacheHelper
{
private static readonly PooledRedisClientManager pool = null;
private static readonly string[] redisHosts = null;
// public static int RedisMaxReadPool = int.Parse(ConfigurationManager.AppSettings["redis_max_read_pool"]);
// public static int RedisMaxWritePool = int.Parse(ConfigurationManager.AppSettings["redis_max_write_pool"]);
public static int RedisMaxReadPool = 3;
public static int RedisMaxWritePool = 1;
static RedisCacheHelper()
{
// var redisHostStr = ConfigurationManager.AppSettings["redis_server_session"];
var redisHostStr = "127.0.0.1:6379";
if (!string.IsNullOrEmpty(redisHostStr))
{
redisHosts = redisHostStr.Split(',');
if (redisHosts.Length > 0)
{
pool = new PooledRedisClientManager(redisHosts, redisHosts,
new RedisClientManagerConfig()
{
MaxWritePoolSize = RedisMaxWritePool,
MaxReadPoolSize = RedisMaxReadPool,
AutoStart = true
});
}
}
}
public static void Add<T>(string key, T value, DateTime expiry)
{
if (value == null)
{
return;
}
if (expiry <= DateTime.Now)
{
Remove(key);
return;
}
try
{
if (pool != null)
{
using (var r = pool.GetClient())
{
if (r != null)
{
r.SendTimeout = 1000;
r.Set(key, value, expiry - DateTime.Now);
}
}
}
}
catch (Exception ex)
{
string msg = string.Format("{0}:{1}发生异常!{2}", "cache", "存储", key);
}
}
public static void Add<T>(string key, T value, TimeSpan slidingExpiration)
{
if (value == null)
{
return;
}
if (slidingExpiration.TotalSeconds <= 0)
{
Remove(key);
return;
}
try
{
if (pool != null)
{
using (var r = pool.GetClient())
{
if (r != null)
{
r.SendTimeout = 1000;
r.Set(key, value, slidingExpiration);
}
}
}
}
catch (Exception ex)
{
string msg = string.Format("{0}:{1}发生异常!{2}", "cache", "存储", key);
}
}
public static T Get<T>(string key)
{
if (string.IsNullOrEmpty(key))
{
return default(T);
}
T obj = default(T);
try
{
if (pool != null)
{
using (var r = pool.GetClient())
{
if (r != null)
{
r.SendTimeout = 1000;
obj = r.Get<T>(key);
}
}
}
}
catch (Exception ex)
{
string msg = string.Format("{0}:{1}发生异常!{2}", "cache", "获取", key);
}
return obj;
}
public static void Remove(string key)
{
try
{
if (pool != null)
{
using (var r = pool.GetClient())
{
if (r != null)
{
r.SendTimeout = 1000;
r.Remove(key);
}
}
}
}
catch (Exception ex)
{
string msg = string.Format("{0}:{1}发生异常!{2}", "cache", "删除", key);
}
}
public static bool Exists(string key)
{
try
{
if (pool != null)
{
using (var r = pool.GetClient())
{
if (r != null)
{
r.SendTimeout = 1000;
return r.ContainsKey(key);
}
}
}
}
catch (Exception ex)
{
string msg = string.Format("{0}:{1}发生异常!{2}", "cache", "是否存在", key);
}
return false;
}
}
}
4测试程序调用
class
Program
{
static
void
Main(
string
[] args)
{
Console.WriteLine(
"Redis写入缓存:zhong"
);
RedisCacheHelper.Add(
"zhong"
,
"zhongzhongzhong"
, DateTime.Now.AddDays(1));
Console.WriteLine(
"Redis获取缓存:zhong"
);
string
str3 = RedisCacheHelper.Get<
string
>(
"zhong"
);
Console.WriteLine(str3);
Console.WriteLine(
"Redis获取缓存:nihao"
);
string
str = RedisCacheHelper.Get<
string
>(
"nihao"
);
Console.WriteLine(str);
Console.WriteLine(
"Redis获取缓存:wei"
);
string
str1 = RedisCacheHelper.Get<
string
>(
"wei"
);
Console.WriteLine(str1);
Console.ReadKey();
}
}
