加载一个byte []成运行时图像 [英] Load a byte[] into an Image at Runtime

问题描述

我有一个字节[] 是由图像表示。我通过 Web客户端下载此图片。当 Web客户端已下载的图片，我使用它的URL引用它，我得到一个字节[] 。我的问题是，我怎么加载字节[] 到图片在WPF元素？谢谢

I have a byte[] that is represented by an Image. I am downloading this Image via a WebClient. When the WebClient has downloaded the picture and I reference it using its URL, I get a byte[]. My question is, how do I load a byte[] into an Image element in WPF? Thank you.

的注意的：这是我在这里问的问题补充：的在运行时生成的图像。我似乎无法得到的工作方式，所以我尝试了不同的方法。

Note: This is complementary to the question I asked here: Generate Image at Runtime. I cannot seem to get that approach to work, so I am trying a different approach.

推荐答案

您可以使用的 的BitmapImage ，并设置其 的StreamSource 包含二进制数据流。如果你想使一个流从字节[] ，使用的 的MemoryStream ：

You can use a BitmapImage, and sets its StreamSource to a stream containing the binary data. If you want to make a stream from a byte[], use a MemoryStream:

MemoryStream stream = new MemoryStream(bytes);
