windows phone 8.1 RT 文件创建错误

Question

根据本教程： https://msdn.microsoft.com/en-us/library/windows/apps/xaml/hh758325.aspx?f=255&MSPPError=-2147217396

我编写了以下函数：

private async void WriteToFile()
{
   StorageFolder folder =
   Windows.Storage.ApplicationData.Current.LocalFolder;
   StorageFile sampleFile =
   await folder.CreateFileAsync("sample.txt", CreationCollisionOption.ReplaceExisting);
}

但是，如果我运行它，我会看到以下错误：

Exception thrown: 'System.ArgumentException' in mscorlib.ni.dll
Use of undefined keyword value 1 for event TaskScheduled.

为什么？我该如何解决这个问题？

Answer 1

它给出了这样的错误 "Additional information: Use of undefined keyword value 1 for event TaskScheduled" 所以可能 sample.txt 无法定义为其未定义的关键字。

将文件名更改为其他名称或"sample1.txt"，它将起作用。

private async void WriteToFile()
{
   StorageFolder folder =
   Windows.Storage.ApplicationData.Current.LocalFolder;
   StorageFile sampleFile =
   await folder.CreateFileAsync("sample1.txt", CreationCollisionOption.ReplaceExisting);
}
