c# – 尝试在InstalledLocation StorageFolder中创建文件同步时访问被拒绝？

概述尝试在InstalledLocation StorageFolder中CreateFileAsync时,我的Access被拒绝 StorageFolder storageFolder = Windows.ApplicationModel.Package.Current.InstalledLocation;StorageFile file = await storageFolder.CreateF 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.
