这个例子，是一个完整的Metro解压缩ZIP文件的例子，首先选择要解压缩的Zip文件，然后自选保存目录。
private
async
void
UnZipFile(
object
sender, RoutedEventArgs e)
{
FileOpenPicker fop =
new
FileOpenPicker();
fop.FileTypeFilter.Add(
".zip"
);
fop.SuggestedStartLocation = PickerLocationId.Desktop;
fop.ViewMode = PickerViewMode.List;
var
zipfile = await fop.PickSingleFileAsync();
byte
[] buffer = WindowsRuntimeBufferExtensions.ToArray(await Windows.Storage.FileIO.ReadBufferAsync(zipfile));
using
(MemoryStream stream =
new
MemoryStream(buffer))
{
ZipArchive zipArchive =
new
ZipArchive(stream, ZipArchiveMode.Read);
FolderPicker fp =
new
FolderPicker();
//Add file types to the FolderPicker
foreach
(
var
zipArchiveEntry
in
zipArchive.Entries)
{
if
(!zipArchiveEntry.FullName.EndsWith(
"/"
))
{
string
fileExtension =
"."
+ Regex.Match(zipArchiveEntry.FullName,
@"[^\.]\w+$"

if

fp.FileTypeFilter.Add(fileExtension);
}
}
fp.SuggestedStartLocation = PickerLocationId.Desktop;
fp.ViewMode = PickerViewMode.List;
StorageFolder unzipfolder = await fp.PickSingleFolderAsync();
int

foreach

in
zipArchive.Entries)
{
if
(!String.IsNullOrEmpty(zipArchiveEntry.FullName))
{

using

using

{
using

{
await fileData.CopyToAsync(s);
await s.FlushAsync();
}
}
}
}
}
progress++;
progressBar.Value = progress * 100 / zipArchive.Entries.Count;
