http://stackoverflow.com/questions/16068710/c-sharp-unable-to-connect-to-a-member-of-the-replica-set-matching-the-read-prefe 上面的链接 我也看了 我 的mongoserverlist 添加的是 路由服务器 单线程访问 没问题 多线程 就报上面的错误

我的 链接的 是 mongodb 集群 private static List<MongoServerAddress> addresses = new List<MongoServerAddress>() { new MongoServerAddress("192.168.1.xx1" , 20000), new MongoServerAddress("192.168.1.xx2" , 20000), new MongoServerAddress("192.168.1.xx3" , 20000) }; MongoServerSettings set = new MongoServerSettings(); set.Servers = addresses; set.ConnectionMode = ConnectionMode.ShardRouter; set.ConnectTimeout = new TimeSpan(0, 0, 0, 60, 0); //set.ReplicaSetName = "shard1"; set.SlaveOk = true; set.ReadPreference = new ReadPreference(ReadPreferenceMode.Secondary); _server = MongoServer.Create(set); 求大神指点啊

我的问题 主要就是 多线程访问 才出上面的问题，是不是多线程访问路由服务器 ，mongodb 集群在切换的时候加锁了？？
