问题描述

我应该从URL获取图像并将其转换为byte[].以下是我取得的成就

I am supposed to get an Image from a url and convert it into byte[]. The following is what I achieved

var webImage = new Image { Aspect = Aspect.AspectFit };
webImage.Source = ImageSource.FromUri(new    Uri("http://xamarin.com/content/images/pages/forms/example-app.png"));

但是现在我无法将图像类型转换为byte[].

这是正确的方法吗?任何帮助将不胜感激.

Is this the correct way to approach? Any kind of help would be appreciated.
