如何让 SharpCompress 将 zip 文件解压到正确的位置并从 zip 中写入文件？

Question

我正在尝试使用 WebView2 在我的网络浏览器上支持扩展，但我坚持提取 .crx 文件。

我为此使用 SharpCompress，因为 .NET 有一些错误，无论如何它只会将文件夹提取到目录的父目录：

private async void Client_DownloadFileCompleted(object? sender, AsyncCompletedEventArgs e)
        {
            try
            {
                LogToConsole("Started creating temp directory");
                await Task.Run(() => Directory.CreateDirectory(Path.Combine(Directory.GetParent(Environment.ProcessPath).FullName, "temp"))); // Create the temp directory to be used here
                LogToConsole($"Finished creating temp directory, extracting extension\nTemp folder path: {Path.Combine(Directory.GetParent(Environment.ProcessPath).FullName, "temp")}\ntemp.crx path: {Path.Combine(Directory.GetParent(Environment.ProcessPath).FullName, "temp.crx")}");
                await Task.Run(() =>
                {
                    try
                    {
                        // The extension I've been using to test this system: https://chromewebstore.google.com/detail/scratch-addons/fbeffbjdlemaoicjdapfpikkikjoneco it downloads perfectly fine
                        // The reason I'm trying to use a third-party package is because .NET fails to extract. I can't remember the error I got from that
                        Stream s = File.Open(Path.Combine(Directory.GetParent(Environment.ProcessPath).FullName, "temp.crx"), FileMode.Open); // Open a FileStream at the CRX location
                        ZipReader reader = ZipReader.Open(s); // Open the CRX
                        MessageBox.Show(Path.Combine(Directory.GetParent(Environment.ProcessPath).FullName, "temp")); // Tell me what the resulting path after unpacking would be
                        reader.WriteAllToDirectory(Path.Combine(Directory.GetParent(Environment.ProcessPath).FullName, "temp")); //  Write to the directory - seems to only write folders for some reason, also writes to the parent of the correct directory and I don't know why
                        //s.Close();
                        // Adding the extension fails because it checks the correct directory and can't find the manifest.json - not sure what's going wrong, I can't even use a WriteAllToFile method because it doesn't exist
                        // Do note that the extension is valid because I could open the file as a zip with 7-Zip
                    } catch (Exception ex)
                    {
                        CrashHandler(ex);
                    }
                });
                //await Task.Run(() => ZipFile.ExtractToDirectory(Path.Combine(Directory.GetParent(Environment.ProcessPath).FullName, "temp.crx"), Path.Combine(Directory.GetParent(Environment.ProcessPath).FullName, "temp"))); // Try to extract the crx file
                LogToConsole("Started adding extension");
                await webview.CoreWebView2.Profile.AddBrowserExtensionAsync(Path.Combine(Directory.GetParent(Environment.ProcessPath).FullName, "temp")); // Add the extension to the profile
                LogToConsole("Clean up");
                File.Delete(Path.Combine(Directory.GetParent(Environment.ProcessPath).FullName, "temp.crx")); // Delete it afterwards, it should've downloaded itself
            } catch (Exception ex)
            {
                CrashHandler(ex);
            }
        }

我还添加了一些评论来描述正在发生的事情。

我多次尝试编辑此代码并切换软件包，但都没有得到好的结果。

Answer 1

.crx

文件使用 ZIP 压缩算法，但它们的标头与

.zip

文件不同。目前，SharpCompress 不支持

.crx

文件。

但是由于它是 GitHub 上的开源项目，因此您可以自己实现对它的支持，并将其作为 PullRequest 提供给 SharpCompress 项目，以使其他人高兴（例如我🙄）。

例如，标题在 here 和 here 中进行了描述。
