.net WPF按钮图像在设计时显示，但在运行时不显示

我在resources文件夹中存储了两个图像，它们是将Build Action设置为resources，将Copy to Output Directory设置为not Copy。图像是“font.png”和“open.png”。但是，当我查看设计器时，按钮中显示的图像与我希望的完全相同；当我运行应用程序时，按钮是空的。下面是我的XAML，我做错了什么

我认为您的图像源URi的格式不正确。应该是这样的

pack://application:,,,/Subfolder/ResourceFile.xaml

（注意“application”后面的冒号）

我通常做的就是吃点东西

Source="Subfolder/ResourceFile.png"

更简单，更可读，更有效；-）

我认为您的URI不正确，您必须将源代码放在答案之前

如果图像是EmbeddedResources，您的URI就可以工作。

看看这些答案：可能是包URI不正确（有多种格式可以工作，我不熟悉您的有效格式），这是我的问题。工作的路径是：

pack://application:，，，/Resources/Open.png
