*	Description:
*		功能:
*		    1、设置连接字符串、选择数据库、获取到连接状态
*		    2、给键添加前缀
*		    3、String操作
*		     【同步(①保存单个键值对)(②根据键获取到对应的值)(③同时保存多个键值对)(④存储一个对象)(⑤获取一个对象)】
*		     
*		     【异步(①保存单个键值对)(②根据键获取到对应的值)(③同时保存多个键值对)(④存储一个对象)(⑤获取一个对象)】
*		    4、Hash操作
*		     【同步(①判断单个键值对是否存在Hash中)(②从Hash中移除单个键值对)(③从Hash中同时移除单个键对应的多个字段列表)(④在Hash中指定值)
*		     (⑤在Hash中同时添加单个键指定的多个字段列表)(⑥在Hash中获取单个键、字段对应的值)(⑦在Hash中同时获取单个键对应的指定字段)
*		     (⑧在Hash中获取单个键对应的所有字段)(⑨在Hash中获取单个键对应的所有值)(⑩在Hash中给单个键的单个字段添加一个对象值)(⑩①在Hash中获取单个键单个字段对应的对象值)】
*		     
*		     【异步(①判断单个键值对是否存在Hash中)(②从Hash中移除单个键值对)(③从Hash中同时移除单个键对应的多个字段列表)(④在Hash中指定值)
*		     (⑤在Hash中同时添加单个键指定的多个字段列表)(⑥在Hash中获取单个键、字段对应的值)(⑦在Hash中同时获取单个键对应的指定字段)
*		     (⑧在Hash中获取单个键对应的所有字段)(⑨在Hash中获取单个键对应的所有值)(⑩在Hash中给单个键的单个字段添加一个对象值)(⑩①在Hash中获取单个键单个字段对应的对象值)】
*		    5、List操作
*		     【同步(①移除并返回列表中该键对应的第一个元素)(②移除并返回列表中该键对应的最后一个元素)(③移除列表中指定键与该值相同的元素)
*		     (④在列表尾部插入值。如果键不存在,先创建再插入值)(⑤在列表头部插入值。如果键不存在,先创建再插入值)(⑥返回列表上该键的长度,如果不存在,返回 0)
*		     (⑦返回在该列表上键所对应的起止点元素)(⑧移除并返回存储在该键列表的第一个元素对象)(⑨移除并返回存储在该键列表的最后一个元素对象)
*		     (⑩在列表尾部插入值。如果键不存在,先创建再插入值)(⑩①在列表头部插入值。如果键不存在,先创建再插入值)】
*		     
*		     【异步(①移除并返回列表中该键对应的第一个元素)(②移除并返回列表中该键对应的最后一个元素)(③移除列表中指定键与该值相同的元素)
*		     (④在列表尾部插入值。如果键不存在,先创建再插入值)(⑤在列表头部插入值。如果键不存在,先创建再插入值)(⑥返回列表上该键的长度,如果不存在,返回 0)

*		     (⑩在列表尾部插入值。如果键不存在,先创建再插入值)(⑩①在列表头部插入值。如果键不存在,先创建再插入值)】
*		    6、SortedSet操作
*		     【同步(① SortedSet 新增)(②在有序集合中返回指定范围的元素,默认情况下从低到高)(③返回有序集合的元素个数)(④返回有序集合的元素个数)
*		     (⑤SortedSet 新增)(⑥增量的得分排序的集合中的成员存储键值键按增量)】
*		     
*		     【异步(① SortedSet 新增)(②在有序集合中返回指定范围的元素,默认情况下从低到高)(③返回有序集合的元素个数)(④返回有序集合的元素个数)
*		     (⑤SortedSet 新增)(⑥增量的得分排序的集合中的成员存储键值键按增量)】
*		    7、Key操作
*		     【同步(①删除指定Key)(②删除指定Key列表)(③检查Key是否存在)(④重命名Key)(⑤设置Key的时间)】
*		     
*		     【异步(①删除指定Key)(②删除指定Key列表)(③检查Key是否存在)(④重命名Key)(⑤设置Key的时间)】
*		    8、发布订阅
*		     【同步(①订阅)(②发布)】
*		     
*		     【异步(①订阅)(②发布)】

三、使用方法

//Redis连接字符串
private static string redisConnStr =null;
//Redis对象
private RedisHelper redis;
       
/// <summary>
/// 打开连接
/// </summary>
public void OpenConnect()
{
   redisConnStr ="127.0.0.1:6379,password=123456,abortConnect=false";
   redis = new RedisHelper(redisConnStr);
}
 

/// <summary>
/// 添加单个字符串的键值对
/// </summary>
/// <returns></returns>
public bool SetSingleKeyOfString(string key,string value)
{
   bool success = false;
   //1-选择数据库
   redis.SelectDB(0);
   //2-添加单个字符串的键值对
   success = redis.SetString(key,value);

   return success;
}
