Question

我在尝试使用MongoDB获取玩家数据时遇到了未知和意外错误？我是mongo的新手，所以我想知道是否有人可以提供帮助。

System.TimeoutException: 'A timeout occured after 3000ms selecting a server using CompositeServerSelector{ Selectors = MongoDB.Driver.MongoClient+AreSessionsSupportedServerSelector, LatencyLimitingServerSelector{ AllowedLatencyRange = 00:00:00.0150000 } }. Client view of cluster state is { ClusterId : "1", ConnectionMode : "Automatic", Type : "Unknown", State : "Disconnected", Servers : [{ ServerId: "{ ClusterId : 1, EndPoint : "127.0.0.1:3306" }", EndPoint: "127.0.0.1:3306", State: "Disconnected", Type: "Unknown", HeartbeatException: "System.InvalidOperationException: Invalid BinaryConnection state transition from 4 to Failed.
   at MongoDB.Driver.Core.Connections.BinaryConnection.OpenConnectionHelper.FailedOpeningConnection(Exception wrappedException)
   at MongoDB.Driver.Core.Connections.BinaryConnection.<OpenHelperAsync>d__48.MoveNext()

C＃：

if (HasAuthenticated)
{
    return;
}

var database = Program.Server.DatabaseHandler.MongoDatabase;
var collection = database.GetCollection<User>("habbo_users");

var playerData = collection.Find(x => x.AuthTicket == authTicket).Limit(1).First();

if (playerData == null)
{
    throw new Exception("Couldn't find players data using this auth ticket.");
}

Console.WriteLine(playerData.Username + " logged in with " + playerData.AuthTicket + " and ID: " + playerData.Id);

如果把它抛到这一行

var playerData = collection.Find(x => x.AuthTicket == authTicket).Limit(1).First();

此部分描述了异常的实际来源：

HeartbeatException：“ System.InvalidOperationException：无效 BinaryConnection状态从4转换为Failed。 ...

这是MongoDB.Driver.Core及更低版本的2.7.0的错误，但仅隐藏了其他一些异常。检查您的MongoDB.Driver.Core版本。如果它低于2.7.1，则将其更新到此版本或更高版本。它不能解决您的问题，但是您将隐藏实际的异常。

实际的异常将在同一位置：... HeartbeatException: [exception text here]。
