C#操作Redis实现读写、订阅发布功能

一、引用dll

using StackExchange.Redis;

二、config配制连接

三、建立连接

private static ConnectionMultiplexer redis = null;
private static bool connected = false;
private IDatabase db = null;
private int current = 0;
public static bool IsConnected { get { Open(); return redis.IsConnected; } }
private static Configuration config = new Configuration();
private static int Open()
{
	if (connected) return 1;
	redis = ConnectionMultiplexer.Connect(config.GetAppSetting("RedisConnectionString"));
	connected = true;
	return 1;
}
public static void Using(Action a)
{
	using (var red = new Redis())
	{
		a(red);
	}
}
public Redis Use(int i)
{
	Open();
	current = i;
	db = redis.GetDatabase(i);
	var t = db.Ping();
	return this;
}

四、redis读写删操作

#region Redis缓存
public void Set(string key, string val, TimeSpan? ts = null)
{
	db.StringSet(key, val, ts);
}


public string Get(string key)
{
	return db.StringGet(key);
}


public void Remove(string key)
{
	db.KeyDelete(key, CommandFlags.HighPriority);
}


public bool Exists(string key)
{
	return db.KeyExists(key);
}


public void Dispose()
{
	db = null;
}
#endregion

五、redis发布订阅

#region Redis发布订阅
public delegate void RedisDeletegate(string str);
public event RedisDeletegate RedisSubMessageEvent;


/// 

/// 订阅
/// 
/// 
public void RedisSub(string subChannel)
{


	redis.GetSubscriber().Subscribe(subChannel, (channel, message) => {
		RedisSubMessageEvent?.Invoke(message); //触发事件
	});


}


/// 

/// 发布
/// 
/// 
/// 
/// 
/// 
public long RedisPub(string channel, T msg)
{


	return redis.GetSubscriber().Publish(channel, msg.ToString());
}


/// 

/// 取消订阅
/// 
/// 
public void Unsubscribe(string channel)
{
	redis.GetSubscriber().Unsubscribe(channel);
}


/// 

/// 取消全部订阅
/// 
public void UnsubscribeAll()
{
	redis.GetSubscriber().UnsubscribeAll();
}
