前言
Redis支持五种数据类型:String(字符串),hash(哈希),list(列表),set(集合),zset(有序集合)
启动redis缓存
redis字符串的存取
使用redis时需要先将redis启动
- //实例化redis,using释放资源
- //如果连接本地的redis并且端口是6379的话可以不指定ip与端口默认就这样
- //直接实例化就行
- using (RedisClient redisClient = new RedisClient()){
- //存值
- redisClient.Set<string>("name",value);
-
- //通过键取值
- string city = redisclient.Get<string>("name");
- };
redis数组的存取
- using (RedisClient redisClient = new RedisClient()){
-
- //往数组里添加数据
- redisclient.AddItemToList("name", "张三");
- redisclient.AddItemToList("name", "李四");
- redisclient.AddItemToList("name", "王五");
- //添加在数组开头
- redisclient.PrependItemToList("test_users","李清照")
-
- //获取数组中的数据(根据下标)
- string val = redisclient.GetItemFromList("name", 1);
-
- //更新数组中的数据(根据下标)
- redisclient.SetItemInList("name", 1, "赵六");
-
- //删除数组中的元素(返回受影响行数)
- long count = redisclient.RemoveItemFromList("name", "赵六");
-
-
- //循环遍历数组中的数据
- List<string> namelist= redisclient.GetAllItemsFromList("name");
- foreach (string item in namelist)
- {
- Console.WriteLine(item);
- }
-
- //获取数组的元素的个数
- long namelistcount = redisclient.GetListCount("name");
-
- //遍历数组的元素的范围(网页分页数据)
- List<string> namelist= redisclient.GetRangeFromList("name", 0, 5);
- foreach (stringitem in namelist)
- {
- Console.WriteLine(item);
- }
-
- }
redis哈希的存取
- using (RedisClient redisClient = new RedisClient()){
- //添加/修改(哈希数组名称,Key,Value)
- redisClient .SetEntryInHash("userhash", "u1", "李白");
- redisClient .SetEntryInHash("userhash", "u2", "韩信");
- redisClient .SetEntryInHash("userhash", "u3", "赵云");
-
- //获取(现在是value = 韩信)根据哈希数组名称+Key,获取value
- string value = redisClient .GetValueFromHash("userhash", "u2");
-
- //删除(删除韩信)
- redisClient .RemoveEntryFromHash("userhash", "u2");
-
- //遍历(返回值是键值对)
- Dictionary<string, string> kvalue = redisClient .GetAllEntriesFromHash("userhash");
- foreach (var item in kvalue)
- {
- Console.WriteLine(item.Key + ":" + item.Value);
- }
-
- //输出所有的key
- List<string> keys = redisClient.GetHashKeys("userhash");
- foreach (string item in keys)
- {
- Console.WriteLine(item);
- }
- //删除所有
- foreach (string key in keys)
- {
- redisClient.RemoveEntryFromHash("userhash", key);
- }
-
- //输出所有的value
- List<string> values = redisClient .GetHashValues("userhash");
- foreach (string item in values)
- {
- Console.WriteLine(item);
- }
-
-
- }
