Question

我已经用谷歌搜索了它，但还没找到任何东西。控制台显示：

The program "[2952] backgroundTaskHost.exe" has exited with the code 1 (0x1)

MainProject获得了Backgroundtask的引用。该任务在等待fileIO阅读器时退出。

StorageFile sampleFile = await storageFolder.GetFileAsync("Klasse.txt");
Stufe = await FileIO.ReadTextAsync(sampleFile);

在我已经调用另一个FileIO Reader之前，但任务没有退出

StorageFile sampleFile = await storageFolder.GetFileAsync("Facher.txt");
Fach = await FileIO.ReadTextAsync(sampleFile);

总而言之：

namespace BackgroundTask
{
    public sealed class BackgroundTask : IBackgroundTask
    {
        string Stufe = "";
        string Fach = "";

        BackgroundTaskDeferral _deferral;
        public async void Run(IBackgroundTaskInstance taskInstance)
        {
            _deferral = taskInstance.GetDeferral();
            StorageFolder storageFolder = ApplicationData.Current.LocalFolder;

            //GetFächer
            try
            {
                StorageFile sampleFile = await storageFolder.GetFileAsync("Facher.txt");
                Fach = await FileIO.ReadTextAsync(sampleFile);
            }
            catch (Exception e) { }

            //GetStufe
            try
            {
                StorageFile sampleFile = await storageFolder.GetFileAsync("Klasse.txt");
                Stufe = await FileIO.ReadTextAsync(sampleFile);
            }
            catch (Exception e) { Debug.WriteLine(e); }
            _deferral.Complete();

           [...]
        }
}
