我正在尝试学习WPF并且我已经制作了一个简单的Tic Tac Toe应用程序。该应用程序有效，但我试图设置它的样式。我无法找到如何为所有按钮设置按钮禁用背景（并保持内容可见）。我的问题是如何在资源字典中设置代码？评论的代码是我尝试过的。为了给所有按钮提供相同的样式，我添加了一个资源字典。
资源字典

根据King King的评论/反馈进行修改
上述示例肯定比OP要求的更多，但是，考虑到问题的背景以及他们对Button控制State样式的兴趣，我认为提供更多细节是有利的（尽管如此）无可置疑地解释。）
在<Setter Property="Tempalte">之前，我正在改变Button控制的基本视觉风格。我希望这一切都不需要解释，因为它似乎是相当自我解释的。
发布<Setter Property="Template">我正在改变Button ControlTemplate的{{3}}（Normal，MouseOver，Pressed ＆amp; Disabled）。这允许我在Button处于其中一种状态时自定义外观。在此示例中，我使用了visual states，以便为Button State转换设置动画。
四个State的样式采用相似的格式（动画渐变背景和动画实体边框），这些状态之间的差异是它们用来提供所需效果的颜色和持续时间。
在我更改主要内容模板VisualState之后，我希望如何呈现Button控件。我提供ContentPresenter，用于显示Button的内容，我将ContentPresenter的某些特征绑定到Button正在模板，允许这些特征如果需要，可以按Button进行控制。 ContentPresenter被Border包围，BrBrush定义了BgBrush（边框画笔）和VisualStates（背景画笔）。这些是ControlTemplate.Triggers模板中引用的相同画笔，并提供了一个默认状态，供它们使用。
最后，我更改Button，根据激活的{Property Value自定义Trigger（此示例中的前景颜色）的视觉样式1}}。
