StackExchange.Redis.DLL 操作redis简化版

直接引入StackExchange.Redis.dll来操作redis

using Newtonsoft.Json;
using StackExchange.Redis;
using System;
using System.Collections.Generic;
using System.Web.Script.Serialization;

namespace Common

    public class RedisHelper

#if FALSE
        RedisHelper redislper = new RedisHelper();
        使用事例
        if (redislper.KeyIsExist(item.Equipmentid, redisadress))//判断是否存在key值
                {
                    var collection = redislper.GetCache<T>(key值);//获取缓存数据                  
                }  
        //写入缓存
        List<T> list = new  List<T>();
         redislper.SetCache<T>(key值, list);
#endif
