CheckForIllegalCrossThreadCalls在WPF

Question

我正在寫我的Bot for Twitch，我現在使用庫稱爲TwichLib（https://github.com/swiftyspiffy/TwitchLib）現在在爲WinForms製作的示例中有方法globalChatMessageReceived並且有CheckForIllegalCrossThreadCalls = false;。所以整個方法看起來像

 private void globalChatMessageReceived(object sender, TwitchChatClient.OnMessageReceivedArgs e) 
     { 
      //Don't do this in production 
      CheckForIllegalCrossThreadCalls = false; 

      richTextBox1.Text = String.Format("#{0} {1}[isSub: {2}]: {3}", e.ChatMessage.Channel, e.ChatMessage.DisplayName, e.ChatMessage.Subscriber, e.ChatMessage.Message) + 
       "\n" + richTextBox1.Text; 
     } 

現在在WPF你已經無法做到這一點CheckForIllegalCrossThreadCalls所以有人點我就應該怎麼正確做到這一點的方法來解決這個CrossThreadCalls？

正確的方式做，這是使用WPF調度執行UI線程上執行的操作：

private void globalChatMessageReceived(object sender, TwitchChatClient.OnMessageReceivedArgs e) 
{ 
    var dispatcher = Application.Current.MainWindow.Dispatcher; 
    // Or use this.Dispatcher if this method is in a window class. 

    dispatcher.BeginInvoke(new Action(() => 
    { 
     richTextBox1.Text = String.Format("#{0} {1}[isSub: {2}]: {3}", e.ChatMessage.Channel, e.ChatMessage.DisplayName, e.ChatMessage.Subscriber, e.ChatMessage.Message) + 
      "\n" + richTextBox1.Text; 
    }); 
} 

或者，更好，使用數據（如果你能）綁定，所以你不需要擔心它。
