            //也可以自定义规则(第一个参数设置)
            //初始化 RedisHelper
            RedisHelper.Initialization(csredis);
            RedisHelper.Set("name1", "祝雷1");//设置值。默认永不过期

            RedisHelper.Set("name1", "祝雷11");//设置值。默认永不过期
            RedisHelper.Set("name2", "祝雷22");//设置值。默认永不过期
            RedisHelper.Set("name", "祝雷");//设置值。默认永不过期

            string str=RedisHelper.Get("name");//取值
