因此,首先,我已经阅读了有关此特定问题的大量主题,但我仍然不知道如何解决该问题。基本上,我试图与websocket通信并将接收到的消息存储在绑定到listview的可观察集合中。我知道我从套接字正确地获得了响应,但是当它尝试将其添加到可观察的集合中时,出现以下错误:
The application called an interface that was marshalled for a different thread. (Exception from HRESULT: 0x8001010E (RPC_E_WRONG_THREAD))
我已经阅读了有关“调度”的一些信息以及其他一些信息,但是我非常困惑!这是我的代码:
public ObservableCollection<string> messageList { get; set; } private void MessageReceived(MessageWebSocket sender, MessageWebSocketMessageReceivedEventArgs args) { string read = ""; try { using (DataReader reader = args.GetDataReader()) { reader.UnicodeEncoding = Windows.Storage.Streams.UnicodeEncoding.Utf8; read = reader.ReadString(reader.UnconsumedBufferLength); } } catch (Exception ex) // For debugging { WebErrorStatus status = WebSocketError.GetStatus(ex.GetBaseException().HResult); // Add your specific error-handling code here. } if (read != "") messageList.Add(read); // this is where I get the error }
这是绑定:
protected override async void OnNavigatedTo(NavigationEventArgs e) { //await Authenticate(); Gameboard.DataContext = Game.GameDetails.Singleton; lstHighScores.ItemsSource = sendInfo.messageList; }
在仍然绑定到我的listview的可观察集合的同时,如何使错误消失?
这解决了我的问题:
Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () => { // Your UI update code goes here! } );
在Windows应用商店应用中获取CoreDispatcher的正确方法
