自己封装的C#操作redis公共类

关于C#操作redis公共类，网上有很多版本，每个版本我都看了，发觉还是不够完美，都存在一个问题，只能操作单一的缓存数据库

redis指令支持上，这里可以自己去扩展，下面分享下我近期封装的一个redis操作类

要用到ServiceStack.Redis V3版，不要用V4 ，v4已经商业化了，有6000次限制

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ServiceStack.Redis;

namespace ZhengXin.Tools
{
    public class RedisUtils
    {
        /// <summary>
        /// 默认过期时间 为秒
        /// </summary>
        private static int secondsTimeOut = 30 * 60;

        #region @Royal改进部分,能操作16个库

        private static readonly Dictionary<int, PooledRedisClientManager> pools = new Dictionary<int, PooledRedisClientManager>();

        static RedisUtils()
        {
            string path = ConfigHelper.GetConfigKeyValue("RedisPath");
            string[] readWriteHosts = new string[] { path };
            string[] readOnlyHosts = new string[] { path };
            //初始化16个缓存库
            for (int i = 0; i <= 15; i++)
            {
                var model = new PooledRedisClientManager(readWriteHosts, readOnlyHosts, new RedisClientManagerConfig
                {
                    MaxWritePoolSize = 50, // “写”链接池链接数
                    MaxReadPoolSize = 50, // “读”链接池链接数
                    AutoStart = true,
                }, i, 100, 20);
                pools.Add(i, model);
            }
        }

        public static PooledRedisClientManager ChooseRedisInstance(int database)
        {
            if (database > 16) return pools[0];

            return pools[database];
        }

        public static void Lpush(string key, string value, int database = 0)
        {
            using (IRedisClient redis = ChooseRedisInstance(database).GetClient())
            {
                redis.PushItemToList(key, value);
            }
        }

        public static string Lpop(string key, int database = 0)
        {
            using (IRedisClient redis = ChooseRedisInstance(database).GetClient())
            {
                return redis.PopItemFromList(key);
            }
        }

        public static List<string> List(string key, int database = 0)
        {
            using (IRedisClient redis = ChooseRedisInstance(database).GetClient())
            {
                return redis.GetAllItemsFromList(key);
            }
        }

        public static bool ItemSet<T>(string key, T t, int timeout = 0, int db = 2)
        {
            using (IRedisClient RClient = ChooseRedisInstance(db).GetClient())
            {
                if (timeout >= 0)
                {
                    if (timeout > 0)
                    {
                        secondsTimeOut = timeout;
                    }
                }
                return RClient.Add<T>(key, t, TimeSpan.FromMinutes(secondsTimeOut));
            }

        }

        public static T ItemGet<T>(string key, int db = 2) where T : class
        {
            using (IRedisClient redis = ChooseRedisInstance(db).GetClient())
            {
                return redis.Get<T>(key);
            }
        }
