問題：in C# Redis : could not connect to redis Instance at 127.0.0.1:6379  （有時候訪問不了，重新整理又可訪問）

使用的是ServiceStack.redis 版本 2.2 ，據說版本4+ 要收費。

代碼：開始用    var result=new RedisClient("127.0.0.1",6379,1"1111"); 

 

後面改為串連池（叢集的方式）/// <summary>/// 串連用戶端管理/// </summary>private static PooledRedisClientManager prcm;/// <summary>/// 建立連結池管理對象/// </summary>public static PooledRedisClientManager CreateManager(){string[] writeServerList = SplitString(redisConfigInfo.WriteServerList, ",");string[] readServerList = SplitString(redisConfigInfo.ReadServerList, ",");return new PooledRedisClientManager(writeServerList, readServerList,new RedisClientManagerConfig{MaxWritePoolSize = redisConfigInfo.MaxWritePoolSize,MaxReadPoolSize = redisConfigInfo.MaxReadPoolSize,DefaultDb = redisConfigInfo.InitalDb,AutoStart = redisConfigInfo.AutoStart,}); //, redisConfigInfo.InitalDb}  /// <summary>/// 用戶端快取作業對象/// </summary>public static IRedisClient GetClient(){if (OpenRedis){if (prcm == null){ prcm = CreateManager();}return prcm.GetClient();}return null;} 但發現用同一個還是串連池並發大還是有問題，從日誌上面看Redis Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use.異常資訊：System.TimeoutException: Redis Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use. could not connect to redis Instance at 127.0.0.1:6379異常資訊：ServiceStack.Redis.RedisException: could not connect to redis Instance at 127.0.0.1:6379 ---> System.Net.Sockets.SocketException: 在一個非通訊端上嘗試了一個操作。 127.0.0.1:6379 後面在網上尋找的時候看到使用using 的方法。 跟串連資料庫一樣的道理，還有開多線程會報錯，要加local鎖RedisConfigInfo類using System;using
