如何在 Windows Phone 7 中解压 zip 文件？

发布于 2024-11-03 21:52:11 字数 507 浏览 5 评论 0原文

我的 Windows Phone 7 项目中有一个 zip 文件。我已将“构建操作”设置为“内容”，并将“复制到输出目录”设置为“始终”。 zip 文件包含文件夹结构。我希望将其完全复制到我的手机项目中。我为此使用 SharpZipLib。这是代码：-

 Stream stremInfo = Application.GetResourceStream(new Uri("xip.zip", UriKind.Relative)).Stream;



        new FastZip(). ExtractZip(stremInfo,
            "",FastZip.Overwrite.Always,null,null,null,true,true);

但是，当调用 ExractZip 时，我收到错误。我得到的异常是“MethodAccessException”。无法调用 GetFullPath()。有人可以让我知道我错过了什么吗？我可以做什么来避免它？

I have a zip file in my Windows Phone 7 project. I have set the Build Action to Content and Copy to output directory to Always. The zip file contains the folder structure. I want this to be copied entirely as it is in my Phone Project. I am using SharpZipLib for this. This is the code :-

 Stream stremInfo = Application.GetResourceStream(new Uri("xip.zip", UriKind.Relative)).Stream;



        new FastZip(). ExtractZip(stremInfo,
            "",FastZip.Overwrite.Always,null,null,null,true,true);

However I get error when ExractZip is called. The exception I get is "MethodAccessException". Cannot call GetFullPath(). Can anybody let me know what am I missing? What can I do to avoid it?

如果您知道想要从 Zip 中获取哪些文件，则无需使用其他库。您可以使用 App.GetResourceStream 电话 API 进入 Zip 并获取文件。

void MainPage_Loaded(object sender, RoutedEventArgs e)
{
    WebClient client = new WebClient();
    client.OpenReadCompleted += new OpenReadCompletedEventHandler(client_OpenReadCompleted);
    client.OpenReadAsync(new Uri("http://www.foo.com/pictures.zip"));
}

void client_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
{
    StreamResourceInfo info = new StreamResourceInfo(e.Result,"");
    StreamResourceInfo pic = App.GetResourceStream(info, new Uri("IMG_1001.jpg", UriKind.Relative));

    BitmapImage bitmap = new BitmapImage();
    bitmap.SetSource(pic.Stream);
    img.Source = bitmap;
}

You dont need to use another library if you know what files you want out of the Zip. You can use the App.GetResourceStream phone API to reach into the Zip and get the file.

void MainPage_Loaded(object sender, RoutedEventArgs e)
{
    WebClient client = new WebClient();
    client.OpenReadCompleted += new OpenReadCompletedEventHandler(client_OpenReadCompleted);
    client.OpenReadAsync(new Uri("http://www.foo.com/pictures.zip"));
}

void client_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
{
    StreamResourceInfo info = new StreamResourceInfo(e.Result,"");
    StreamResourceInfo pic = App.GetResourceStream(info, new Uri("IMG_1001.jpg", UriKind.Relative));

    BitmapImage bitmap = new BitmapImage();
    bitmap.SetSource(pic.Stream);
    img.Source = bitmap;
}
