尝试在InstalledLocation StorageFolder中CreateFileAsync时,我的Access被拒绝
StorageFolder storageFolder = Windows.ApplicationModel.Package.Current.InstalledLocation; StorageFile file = await storageFolder.CreateFileAsync("fileNmae",Windows.Storage.CreationCollisionOption.ReplaceExisting);
我也试过
var storageFolder = await StorageFolder.GetFolderFromPathAsync("ms-appx:///");
并且“价值不在预期范围内”
我可以在Windows.Storage.ApplicationData.Current.LocalFolder中创建CreateFileAsync,然后将CopyAsync复制到InstalledLocation StorageFolder?
StorageFolder storageFolder = Windows.Storage.ApplicationData.Current.LocalFolder; StorageFile file = await storageFolder.CreateFileAsync("fileName",Windows.Storage.CreationCollisionOption.ReplaceExisting); StorageFolder installedLocationFolder = Windows.ApplicationModel.Package.Current.InstalledLocation; var result = await file.CopyAsync(installedLocationFolder,"fileName",Windows.Storage.NameCollisionOption.ReplaceExisting);
但是在InstalledLocation StorageFolder中的CreateFileAsync允许Access被拒绝?
那是因为安全原因还是我在这里编码错了?
解决方法
该应用的安装目录是只读位置.另外,不建议您将数据文件写入安装位置.如果您需要存储数据,仅供应用程序使用,您应该使用
StorageFolder localFolder = ApplicationData.Current.LocalFolder;
要么
Windows.Storage.StorageFolder temporaryFolder = ApplicationData.Current.TemporaryFolder;
取决于数据的生命周期.
