如何从隔离存储中读取图像并将其显示在 Image 元素上? [英] How to read a image from isolated-storage and display it on Image element?

问题描述

我需要从 IsolatedStorage，并将其显示在 Image UIElement 上.我调查了 MSDN，发现我无法从 IndependentStorage 获取 Uri.我可以获得保存的 jpeg 图像文件的流.

I need to load an image from IsolatedStorage, and display it on an Image UIElement. I have surveyed MSDN, and I found I cannot get an Uri from IsolatedStorage. I could get a stream for the saved jpeg image file.

获得 jpeg 文件流后，如何将其显示在 Image 元素上?

After I get the jpeg file stream, how do I show it on an Image element?

推荐答案

使用 BitmapImage.SetSource 读取流然后将 Image.Source 设置为 BitmapImage:

Use BitmapImage.SetSource to read the stream and then set the Image.Source to the BitmapImage:

Stream jpegStream;
var image1 = new BitmapImage();
image1.SetSource(jpegStream);
Image image = new Image();
image.Source = image1;
