C# StackExchange.Redis使用
RedisManage类
管理类，提供Redis管理上下文，此处单例模式实现获取对应的Redis管理器
using StackExchange.Redis;
namespace DataMigrationService
{
public class RedisManage
{
public static readonly ConfigurationOptions ConfigurationOptions = ConfigurationOptions.Parse("127.0.0.1:6379");
private static readonly object Locker = new object();
private static ConnectionMultiplexer _redisConn;
/// <summary>
/// 单例获取
/// </summary>
public static ConnectionMultiplexer RedisConn
{
get
{
if (_redisConn == null)
{
// 锁定某一代码块，让同一时间只有一个线程访问该代码块
lock (Locker)
{
if (_redisConn == null || !_redisConn.IsConnected)
{
_redisConn = ConnectionMultiplexer.Connect(ConfigurationOptions);
}
}
}
return _redisConn;
}
}
}
}
RedisBase类
基础操作类，提供数据获取等的相关指令
using StackExchange.Redis;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace DataMigrationService
{
public abstract class RedisBase
{
public static IDatabase _database;
public static IServer _server;
private static int dbIndex = -1;
public RedisBase()
{
_database = RedisManage.RedisConn.GetDatabase(dbIndex);
_server = RedisManage.RedisConn.GetServer(RedisManage.RedisConn.GetEndPoints().First());
}
public RedisBase(int index)
{
dbIndex = index;
_database = RedisManage.RedisConn.GetDatabase(index);
_server = RedisManage.RedisConn.GetServer(RedisManage.RedisConn.GetEndPoints().First());
}
static RedisBase()
{
_database = RedisManage.RedisConn.GetDatabase(dbIndex);
_server = RedisManage.RedisConn.GetServer(RedisManage.RedisConn.GetEndPoints().First());
}
