Windows Phone 8线程无效的跨线程访问

我正在为Windows Phone 8制作一个Tic-Tac-Toe游戏，我希望游戏与其自身一起作为主菜单的背景

private Button[] bts; private List temp = new List(); private int[,] winningConditions; private int counter; private string Board; public MainPage() { InitializeComponent(); bts = new[] { _1, _2, _3, _4, _5, _6, _7, _8, _9 }; winningConditions = new[,] { { 0, 1, 2 }, { 3, 4, 5 }, { 6, 7, 8 }, { 0, 3, 6 }, { 1, 4, 7 }, { 2, 5, 8 }, { 0, 4, 8 }, { 2, 4, 6 } }; counter = 0; bTextFont(); } private void NewGame() { foreach (Button i in bts) i.Content = "";//here I get an Exception saying Invalid cross-thread access while (true) { NearlyHuman(); someOneWon(); counter++; } } private void form_Loaded(object sender, RoutedEventArgs e) { Thread backGround = new Thread(new ThreadStart(NewGame)); backGround.Start(); } 

Answer 1

您无法直接从任何其他线程访问UI线程。 所以，在Dispatcher.BeginInvoke（）中填充您的UI访问代码

 Dispatcher.BeginInvoke(() => { foreach (Button i in bts) i.Content = ""; }); 

Answer 2
