本文介绍了一个使用Redis的C#助手类RedisHelper，通过单例模式管理Redis连接，并提供了基本的Redis操作示例，如SET、GET和HMSET等。

RedisHelper.cs

using StackExchange.Redis;

namespace ConsoleApplication2
{
    //学习使用Nuget配置NewtonJson.dll

    // PM> install-package newtonsoft.json
    // PM> Install-Package StackExchange.Redis
    public class RedisHelper
    {
        private static readonly ConfigurationOptions ConfigurationOptions = ConfigurationOptions.Parse("127.0.0.1" + ":" + "6379");
        private static readonly object Locker = new object();
        private static ConnectionMultiplexer _redisConn;

        /// <summary>
        /// 单例获取
        /// </summary>
        public static ConnectionMultiplexer RedisConn
        {
            get
            {
                if (_redisConn == null)
                {
                    lock (Locker)
                    {
                        if (_redisConn == null || !_redisConn.IsConnected)
                        {
                            _redisConn = ConnectionMultiplexer.Connect(ConfigurationOptions);
                        }
                    }
                }
                return _redisConn;
            }
        }
    }
}

用法：

        static void Main(string[] args)
        {
            //http://www.cnblogs.com/weixiao520/p/5765358.html

            var db = RedisHelper.RedisConn.GetDatabase();
            var key = "keyTest1";
            //SET命令
            db.StringSet(key, "1093939393939393939");
            //GET命令
            var value = db.StringGet(key);
            Console.WriteLine(value);


            //HMSET
            key = "hashTest";
            db.HashSet(key, new[] { new HashEntry("b", "2"), new HashEntry("c", "3") });
            //HMGET
            var values = db.HashGetAll(key);
            Console.WriteLine(values[0].Name + "///" + values[0].Value);

            Console.ReadLine();
        }
