C#操作Redis存储基础(续一)
上篇文章介绍了最基本的C#操纵Redis的方法，因为自己也在学习中，也是找资料学习，然后自己写，自己理解，也一直在补充，今天看一下比较高级的一点的用法，针对初学者哈。
这里我还是用的winform写的，还是framwork3.5的哈。看过上篇博文的知道，对于服务器端口，ID，过期时间等都是在代码中硬编码写的，相信现在在开发中你这样写你经理你同事一大堆他们得拿刀卸了你，所以一般都写在配置文件里，然后读取配置尽心连接，设置等，但是在配置文件中，没有专门得配置节让我们配置，咱们自己可以封装一个实体去存储配置。
需要继承ConfigurationSection这个类，然后用ConfigurationProperty对配置节得属性做对照保存，然后读取配置，在配置文件中配置好之后，要做一下这个实体注册， 代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Configuration;
namespace RedisDemo
{
public sealed class RedisConfigInfo : ConfigurationSection
{
#region 配置文件中属性定义
///
<configuration>
<configSections>
<section name="RedisConfig" type="RedisDemo.RedisConfigInfo, RedisDemo"/>
configSections>
<RedisConfig WriteServerList="127.0.0.1:6379"
ReadServerList="127.0.0.1:6379"
MaxWritePoolSize="60"
MaxReadPoolSize="60"
AutoStart="true"
LocalCacheTime="180"
RecordeLog="false">
RedisConfig>
configuration>上面这些配置读取做好了，就该做C#操作Redis服务器的帮助类了，比如创建客户端，解析配置文件的配置信息，跟ADO.NET那一套一样，都有个流程性的东西，写来写去一样，我也是按着别人的例子写的：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ServiceStack.Redis;
namespace RedisDemo
{
public class RedisManager
{
public static RedisConfigInfo info = RedisConfigInfo.GetConfig();
//缓存客户端
public static PooledRedisClientManager prcm;
//缓存初始化
static RedisManager()
{
CreatRedisManager();
}
public static void CreatRedisManager()
{
string[] writeServerList = SplitString(info.WriteServerList, ",");
string[] readServerList = SplitString(info.ReadServerList, ",");
prcm = new PooledRedisClientManager(readServerList, writeServerList,
new RedisClientManagerConfig
{
MaxWritePoolSize = info.MaxWritePoolSize,
MaxReadPoolSize = info.MaxReadPoolSize,
AutoStart = info.AutoStart,
});
}
private static string[] SplitString(string strSource, string split)
{
return strSource.Split(split.ToArray());
}
public static IRedisClient GetRedisClient()
{
if (prcm == null)
{
CreatRedisManager();
}
return prcm.GetClient();
}
}
}
完事儿就是调用啦，界面很简单：按钮1 其实没做什么事儿，刚开始为测试连接成功不成功用，新增 删除就不用解释了，
下面的那个黑黑的是个列表。
一个User类，一个UserGroup类做实体模拟用户与用户组的业务，增删改查等，结合linq，操作起来也是方便的不要不要的了。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace RedisDemo.Models
{
public class User
{
public long UserID { get; set; }
public string UserName { get; set; }
public UserGroup userGroup { get; set; }
}
}
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace RedisDemo.Models
{
public class UserGroup
{
public long GroupID { get; set; }
public string GroupName { get; set; }
}
}
代码里木有有注释，但看着方法名也清楚啦，看着代码，然后调试模式走一遍，比我码字清晰，而且易懂。我代码里就一行注释，那个地方是个坑，因为时间不早了急着睡觉还要出差，就直接用文本框的内容当作id先传进去了，正确的方法应该是根据文本框的信息查询出这条信息，然后把这条信息的ID传进去。(这里的ID，是Redis数据库中的系统自增长的那个ID哦，跟oracle中的Sequence差不多啦，代码中那个GetNextSequence就是获取下个自增长的数啦)
我Form1中的实现代码如下啦：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using RedisDemo.Models;
namespace RedisDemo
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
//var aaa = RedisConfigInfo.GetConfig();
}
private void New_Click(object sender, EventArgs e)
{
var redisClient = RedisManager.GetRedisClient();
var user = redisClient.GetTypedClient();
var userToAdd = new User
{
UserID = user.GetNextSequence(),
UserName = textBox3.Text,
userGroup = new UserGroup { GroupID = 1L, GroupName = textBox2.Text }
};
user.Store(userToAdd);
dataGridView1.DataSource = null;
List list = user.GetAll().ToList();
dataGridView1.DataSource = list;
label1.Text = list[1].userGroup.GroupName;
redisClient.Dispose();
}
protected void button1_Click(object sender, EventArgs e)
{
System.Diagnostics.Process.Start("E:\\redis\\redis-server.exe");//此处为Redis的存储路径
using (var redisClient = RedisManager.GetRedisClient())
{
var user = redisClient.GetTypedClient();
if (user.GetAll().Count > 0)
user.DeleteAll();
var userToInsert = new User
{
UserID = user.GetNextSequence(),
UserName = textBox3.Text,
userGroup = new UserGroup { GroupID = redisClient.GetTypedClient().GetNextSequence(), GroupName = textBox2.Text }
};
user.Store(userToInsert);
dataGridView1.DataSource = null;
List list = user.GetAll().ToList();
dataGridView1.DataSource = list;
label1.Text = list[1].userGroup.GroupName;
}
}
void GetAll(object sender, EventArgs e)
{
using (var redisClient = RedisManager.GetRedisClient())
{
var user = redisClient.GetTypedClient();
if (user.GetAll().Count > 0)
{
List list = user.GetAll().ToList();
dataGridView1.DataSource = list;
}
}
}
void Insert()
{
using (var redisClient = RedisManager.GetRedisClient())
{
var user = redisClient.GetTypedClient();
var userToInsert = new User
{
UserID = user.GetNextSequence(),
UserName = textBox3.Text,
userGroup = new UserGroup { GroupID = redisClient.GetTypedClient().GetNextSequence(), GroupName = textBox2.Text }
};
user.Store(userToInsert);
dataGridView1.DataSource = null;
List list = user.GetAll().ToList();
dataGridView1.DataSource = list;
label1.Text = list[1].userGroup.GroupName;
}
}
void Delete()
{
using (var redisClient = RedisManager.GetRedisClient())
{
var user = redisClient.GetTypedClient();
user.DeleteById(textBox3.Text); //实际应该是ID 此处应该报错？？？？
if (user.GetAll().Count > 0)
{
List list = user.GetAll().ToList();
dataGridView1.DataSource = list;
label1.Text = list[1].userGroup.GroupName;
}
}
}
void Search()
{
using (var redisClient = RedisManager.GetRedisClient())
{
var user = redisClient.GetTypedClient();
var userList = user.GetAll().Where(x => x.userGroup.GroupName == textBox2.Text).ToList();
if (userList.Count > 0)
{
dataGridView1.DataSource = userList;
label1.Text = userList[0].userGroup.GroupName;
}
}
}
private void button1_Click_1(object sender, EventArgs e)
{
}
}
}
