我想将解压缩的文件保存到IsolatedStorage中的一个文件夹中。我已经从IsolatedStorage中读取了文件压缩文件，现在想将它们解压缩到一个文件夹中。我试过这样做:-

private async Task UnZipFile(string fileName)
    {
        IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication();
        using (IsolatedStorageFileStream fileStream = myIsolatedStorage.OpenFile(fileName, FileMode.Open, FileAccess.ReadWrite))
        {
            UnZipper unzip = new UnZipper(fileStream);
            var filename = unzip.FileNamesInZip.FirstOrDefault();
            if (filename != null)
            {                                   
              // i can have the stream too. like this.
              // var zipStream = unzip.GetFileStream(filename)
              // here i am not getting how to save unzip file to a folder.
            } 
    }

将解压缩的文件保存到一个文件夹中

这是我得到的:)希望它能帮助到别人。

private async Task UnZipFile()
{
    // you can use Isolated storage too
    var myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication();
    using (var fileStream = Application.GetResourceStream(new Uri("sample.zip", UriKind.Relative)).Stream)
    {
        var unzip = new UnZipper(fileStream);
        foreach (string filename in unzip.FileNamesInZip)
        {
            if (!string.IsNullOrEmpty(filename))
            {
                if (filename.Any(m => m.Equals('/')))
                {
                    myIsolatedStorage.CreateDirectory(filename.Substring(0, filename.LastIndexOfAny(new char[] { '/' })));
                }
                //save file entry to storage
                using (var streamWriter =
                    new StreamWriter(new IsolatedStorageFileStream(filename,
                        FileMode.Create,
                        FileAccess.ReadWrite,
                        myIsolatedStorage)))
                {
                    streamWriter.Write(unzip.GetFileStream(filename));
                }
            }
        }
    }
}
