推荐答案

您可以使用的方法是 此处描述.由于您的问题没有指定代码更改背景所采取的操作，因此，您可能需要稍微调整引用链接中的代码.请注意，如果您打算按照帖子中建议的路径进行操作，则可能需要从转换器返回 ImageBrush.

An approach you can use is described here. Since your question does not specify the action the code takes to change the background, therefore, you may have to adapt the code in the referred link a bit. Note that you may have to return the ImageBrush from the converter, if you intend to go down the path suggested in the post.
