Question

我正在尝试将SharpZip.unzipper用于我的Windows Phone 8.1。但是它没有阅读一些代码。由于我对Windows Phone开发还不熟悉，请告诉我WP8.1以下代码的替代方法

using System.Windows.Resources;

public Stream GetFileStream(string filename)
        {
            if (fileEntries == null)
                fileEntries = ParseCentralDirectory(); //We need to do this in case the zip is in a format Silverligth doesn't like
            long position = this.stream.Position;
            this.stream.Seek(0, SeekOrigin.Begin);
            Uri fileUri = new Uri(filename, UriKind.Relative);
            StreamResourceInfo info = new StreamResourceInfo(this.stream, null);
            StreamResourceInfo stream = System.Windows.Application.GetResourceStream(info, fileUri);
            this.stream.Position = position;
            if (stream != null)
                return stream.Stream;
            return null;
        }

Windows.Resources似乎不见了我无法致电StreamResourceInfo, System.Windows.Application

我尝试过使用App。但GetResourceSteam

没有任何功能

我不知道该怎么做

WP8.1运行时与WP8.1 Silverlight之间存在很多差异。

您拥有的代码示例将在WP8.0 SL和WP8.1 SL上运行。

看起来您创建了一个Windows Phone 8.1运行时项目。没有System.Windows.Application.GetResourceStream()

将其转换为兼容的8.1运行时流，或者重新创建项目以改为以Silverlight为目标。

// sample
private async void ZipLibraryTest()
{
    // create the full path
    string zip = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, "filename.zip");

    // create the storage file with the file name
    StorageFile sf = await StorageFile.GetFileFromPathAsync(zip);

    // create the IO Stream
    using (System.IO.Stream output = await sf.OpenStreamForWriteAsync())
    {
        // open the zip file for writing, use the stream from the file
        ZipFile zf = ZipFile.Create(output);

        // rest of your code
        // ...
        // ...

        // close the zip file
        zf.Close();
    }
}

使用SharpZipper解压缩WP8.1中的文件
