c# - Winrt c#将图像从资产复制到本地存储

Question

我今天来找你是因为我不知道如何将图像从资产复制到本地存储。我尝试类似的东西：

StorageFile file = await StorageFile.GetFileFromApplicationUriAsync(
    new Uri("appx:///Assets/image.png"));

await file.CopyAsync(ApplicationData.Current.LocalFolder, "image.png");

但它根本不起作用。有谁知道这样做对吗？谢谢你的时间，问候。

Answer 1

您的 Uri 方案无效。它应该是ms-appx:，而不是appx:：

StorageFile file = await StorageFile.GetFileFromApplicationUriAsync(
    new Uri("ms-appx:///Assets/image.png"));

await file.CopyAsync(ApplicationData.Current.LocalFolder, "image.png");

有关有效的 Uri 方案，请参阅此帖子：Windows 8 应用程序中支持的 URI 方案
