c# - 如何在UWP中解压文件

Question

我正在尝试解压缩文件，但我总是有

Access to the path 'C:\Users\Kosov Denis\Downloads\12.epub' is denied.

我穿了什么？

await Task.Run(() =>
            {
                ZipFile.ExtractToDirectory(file.Path,
                    ApplicationData.Current.LocalCacheFolder.Path +
                    string.Format(@"\{0}", file.Name.Replace(file.FileType, "")));
            });

我也遇到过和你一样的问题，我google了半天发现UWP好像不能直接通过路径访问文件，如果要访问本地文件，需要使用文件拾取，见: hele . 我用曲线来解决这个问题:

StorageFolder folder;
folder = ApplicationData.Current.LocalFolder;

//Open the file picker
var _openFile = new FileOpenPicker();
_openFile.SuggestedStartLocation = PickerLocationId.DocumentsLibrary;
_openFile.ViewMode = PickerViewMode.List;
_openFile.FileTypeFilter.Add(".zip");
StorageFile file = await _openFile.PickSingleFileAsync();

//Read the file stream
Stream a = await file.OpenStreamForReadAsync();

//unzip
ZipArchive archive = new ZipArchive(a);
archive.ExtractToDirectory(folder.Path);

ZipArchive Class
