Question

我正在构建一个Windows手机游戏数据库。我想刮掉那些数据。但我找不到任何库或api或文档。

请不要与此重复此问题：windows store api to access metro and phone apps information

因为该答案仅与Windows PC应用有关，而不是Windows手机应用。

样本：

List<WindowsPhoneAppInfo> data = await WindowsPhoneGamesScraper.GetFeaturedWindowsPhoneGames("en-US");//, categories.ToList(), types.ToList());
data.AddRange(await WindowsPhoneGamesScraper.GetWindowsPhoneApps("en-US", UpdateAction));
data = data.Distinct().ToList();
lboGames.ItemsSource = data;

您可以使用所有受支持的文化调用相同的操作。

需要Windows Phone Games抓取API
