1.新建一个.Net Core控制台应用程序，用Nuget导入驱动
打开程序包管理控制台，
执行以下代码。
PM> Install-Package ServiceStack.Redis
即可添加Redis的引用。
2.StringDemo
String类型是最常用的数据类型，在Redis中以KKey/Value存储。
using System;
using System.Collections.Generic;
using System.Text;
using ServiceStack.Redis;
using ServiceStack.Text;
namespace RedisDotNetDemo
{
class StringDemo
{
public static void Start()
{
var redisMangement = new RedisManagerPool("127.0.0.1:6379");
var client = redisMangement.GetClient();
client.Set<int>("pwd", 111); //普通字符串
int pwd = client.Get<int>("pwd");
Console.WriteLine(pwd);
var todoTools = client.As<Todo>();
Todo todo=new Todo(){Content = "123",Id =todoTools.GetNextSequence(),Order = 1};
client.Set<Todo>("todo", todo); //object
Todo getTodo = client.Get<Todo>("todo");
Console.WriteLine(getTodo.Content);
List<Todo> list=new List<Todo>(){new Todo(){Content = "123"},new Todo(){Content = "234"}}; //List<Object>
client.Set("list", list);
List<Todo> getList = client.Get<List<Todo>>("list");
foreach (var VARIABLE in getList)
{
Console.WriteLine(VARIABLE.Content);
}
Console.ReadLine();
}
}
class Todo
{
public long Id { get; set; }
public string Content { get; set; }
public int Order { get; set; }
public bool Done { get; set; }
}
}
3.HashDemo
如何,Hash在Redis采用 (HashId,Key，Value)进行存储
一个HashId 可以包含多个key，一个key对应着一个value
using System;
using System.Collections.Generic;
using System.Text;
using ServiceStack.Redis;
namespace RedisDotNetDemo
{
class HashDemo
{
public static void Start()
{
var redisMangement = new RedisManagerPool("127.0.0.1:6379");
var client = redisMangement.GetClient();
client.SetEntryInHash("test", "123", "aaaaa"); //存储一次数据 test是hashid，123是key，aaaa是value
List<string> listKeys = client.GetHashKeys("test"); //获取test哈希下的所有key
Console.WriteLine("keys in test");
foreach (var VARIABLE in listKeys)
{
Console.WriteLine(VARIABLE);
}
List<string> listValue = client.GetHashValues("test"); //获取test哈希下的所有值
Console.WriteLine("test 里的所有值");
foreach (var VARIABLE in listValue)
{
Console.WriteLine(VARIABLE);
}
string value = client.GetValueFromHash("test", listKeys[0]); //获取test哈希下，第一个Key对应的值
Console.WriteLine("test 下的key"+listKeys[0]+"对应的值"+value);
}
}
}
4.ListDemo
list是一个链表结构，key可以理解为链表的名字，然后往这个名字所对应的链表里加值。，list可以以队/栈的形式进行工作。
using System;
using System.Collections.Generic;
using System.Text;
using ServiceStack.Redis;
namespace RedisDotNetDemo
{
class ListDemo
{
public static void Start()
{
var redisMangement = new RedisManagerPool("127.0.0.1:6379");
var client = redisMangement.GetClient();
//队列的使用 //先进先出
client.EnqueueItemOnList("name","zhangsan"); //入列
client.EnqueueItemOnList("name","lisi"); //入列
long count = client.GetListCount("name");
for (int i = 0; i < count; i++)
{
Console.WriteLine(client.DequeueItemFromList("name")); //出列
}
//栈的使用 //先进后出
client.PushItemToList("name2","wangwu"); //推入
client.PushItemToList("name2","maliu"); //推入
long count2 = client.GetListCount("name2");
for (int i = 0; i < count2; i++)
{
Console.WriteLine(client.PopItemFromList("name2")); //弹出
}
}
}
}
5 SetDemo
它是string类型的无序集合。set是通过hash table实现的，添加，删除和查找,对集合我们可以取并集，交集，差集.
using System;
using System.Collections.Generic;
using System.Text;
using ServiceStack.Redis;
namespace RedisDotNetDemo
{
class SetDemo
{//它是string类型的无序集合。set是通过hash table实现的，添加，删除和查找,对集合我们可以取并集，交集，差集.
public static void Start()
{
var redisMangement = new RedisManagerPool("127.0.0.1:6379");
var client = redisMangement.GetClient();
//对Set类型进行操作
client.AddItemToSet("a3", "ddd");
client.AddItemToSet("a3", "ccc");
client.AddItemToSet("a3", "tttt");
client.AddItemToSet("a3", "sssh");
client.AddItemToSet("a3", "hhhh");
HashSet<string> hashSet = client.GetAllItemsFromSet("a3");
foreach (var VARIABLE in hashSet)
{
Console.WriteLine(VARIABLE);
}
//求并集
client.AddItemToSet("a4", "hhhh");
client.AddItemToSet("a4", "h777");
HashSet<string> hashSetUnion = client.GetUnionFromSets(new string[] {"a3", "a4"});
Console.WriteLine("并集");
foreach (var VARIABLE in hashSetUnion)
{
Console.WriteLine(VARIABLE);
}
//求交集
HashSet<string> hashsetInter = client.GetIntersectFromSets(new string[] { "a3","a4" });
Console.WriteLine("交集");
foreach (var VARIABLE in hashsetInter)
{
Console.WriteLine(VARIABLE);
}
//求差集
HashSet<string> hashsetDifference = client.GetDifferencesFromSet("a3", new string[] { "a4" });
Console.WriteLine("差集");
foreach (var VARIABLE in hashsetDifference)
{
Console.WriteLine(VARIABLE);
}
}
}
}
6.SortedSetDemo
SortedSet我只知道它相较于Set,它是有序的，而Set是无需的，而且用户还可以调整SortedSet中value的位置，至于具体怎么在.Net环境下调整，暂时没有学会，就不在此班门弄斧，给出一个SortedDemo的存和取得例子。
using System;
using System.Collections.Generic;
using System.Text;
using ServiceStack.Redis;
namespace RedisDotNetDemo
{
//区别是set不是自动有序的，而sorted set可以通过用户额外提供一个优先级(score)的参数来为成员排序，并且是插入有序的，即自动排序。
//当你需要一个有序的并且不重复的集合列表，那么可以选择sorted set数据结构，
class SortedSetDemo
{
public static void Start()
{
var redisMangement = new RedisManagerPool("127.0.0.1:6379");
var client = redisMangement.GetClient();
client.AddItemToSortedSet("a5", "ffff");
client.AddItemToSortedSet("a5", "bbbb");
client.AddItemToSortedSet("a5", "gggg");
client.AddItemToSortedSet("a5", "cccc");
client.AddItemToSortedSet("a5", "waaa");
System.Collections.Generic.List<string> list = client.GetAllItemsFromSortedSet("a5");
foreach (string str in list)
{
Console.WriteLine(str);
}
}
}
}
以上是我对Redis中几种数据类型得用法得总结，如有不对得地方，欢迎大家批评指正。
