我开发了一个应用程序,它根据后台任务将内容粘贴到剪贴板。
public sealed class ToastBackgroundTask : IBackgroundTask {
public void Run(IBackgroundTaskInstance taskInstance) {
//Inside here developer can retrieve and consume the pre-defined
//arguments and user inputs;
var toastArgs = taskInstance.TriggerDetails as ToastNotificationActionTriggerDetail;
var argument = toastArgs.Argument;
SetClipbordContent(toastArgs.Argument);
}
public static void SetClipbordContent(string text) {
var dataPackage = new DataPackage();
dataPackage.SetText(text);
Clipboard.SetContent(dataPackage);
}
}
但是当我执行
行时Clipboard.SetContent(dataPackage);
提出这个例外:
The activation of a single-threaded class from MTA is not supported.
(Exception from HRESULT: 0x8000001D)
在经典.Net Framework中处理此secario的常用解决方法是使用Thread类在STA上下文中执行此部分代码(C# Clipboard.GetText())但我不知道如何在UWP中执行此操作
答案 0 :(得分:0)
我过去曾使用它在后台线程的UI线程上执行...
await CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, async () => {
// Do something...
}
