Question

我一直在用Windows Forms开发一些简单的应用程序（仅用于教育目的），现在我开始学习WPF，但对我来说似乎有点复杂。

我想创建一个简单的菜单，就像你可以在图片中看到的那样。我一直试图在谷歌和YouTube上找到它，但我刚刚找到了很多关于“汉堡菜单”的教程，这不是我想要的。

这是WPF闪耀的一个领域：您描述的布局只需一个重新设置的标签控件即可实现。

使用TabStripPlacement Left的<{1}}开始使用无样式的标签控件：

然后修改TabControl样式，在TabPanel后面添加渐变和边距：

添加图片并覆盖TabItem样式以设置字体并删除背景。我用雪佛龙来表示选择而不是用粗体表示文本，但这样做的处理方法也是一样的。

以下是用于上述屏幕截图的完整XAML：
