保存的BitmapImage对象作为本地存储在Windows 8的文件？ [英] Saving a BitmapImage object as a file in local storage in windows 8?

问题描述

我有一个BitmapImage的对象，它已经拥有了源等集。我只是想将其保存到我的应用程序的本地存储文件夹，这样我就可以在程序中的其他点引用它。我只是无法弄清楚如何从对象得到它虽然文件！我发现类似的问题解决方案，为WP7，但它只是不一样的。

I have a BitmapImage object, which already has its source etc set. I simply want to save it to my apps local storage folder, so that I can reference it at other points in the program. I just cannot figure out how to get it from object to file though! I've found solutions to similar problems for WP7, but its just not the same.

Ive得到尽可能从Base64编码字符串创建我的形象（这可以作为我可以将图像加载到用户界面的图像浏览器，看看它），并把它称为 IMG ，我知道我需要得到它的 ApplicationData.Current .LocalFolder ，但我不知道如何将它转换。有谁知道？

Ive got as far as creating my image from a Base64 string (which works as I can load the image into a UI image viewer and see it) and have called it img, and I know I need to get it to ApplicationData.Current.LocalFolder, but I have no idea how to convert it. Does anyone know?

推荐答案

它是从相机UI？

var _Photo = await new CameraCaptureUI()
    .CaptureFileAsync(CameraCaptureUIMode.PhotoOrVideo);
await _Photo.MoveAsync(ApplicationData.Current.LocalFolder);

从打开的文件呢？然后你只需要：

Is it from opening the file? Then you just need:

await _Photo.MoveAsync(ApplicationData.Current.LocalFolder);

不过，如果你只是有一个BitmapImage的，你不能获得图像出来。相反，你需要回到原来的源或文件。这是唯一的方法。 参考
