WPF仿网易云音乐系列（一、左侧菜单栏：Expander+RadioButton）

原文:WPF仿网易云音乐系列（一、左侧菜单栏：Expander+RadioButton）

1.简介

上一篇咱们说到，网易云音乐的左侧菜单栏可以通过Expander+RadioButton来实现，具体如何实现，咱们下面开始干；

首先来一张网易云音乐PC版原图（个人觉得PC版比UWP版左侧菜单好看点）：

然后当然是再上以下咱们做出的效果图了：

还原度百分之百有没有。。。

2.上硬菜

首先是无边框窗口方案，这里使用的是DMSkin for WPF,Github地址：https://github.com/944095635/DMSkin-for-WPF

Expander

 1 <ControlTemplate x:Key="ExpanderToggleButton" TargetType="ToggleButton">

以上就是Expander+RadioButton的核心代码了；其中用到的图标可以到阿里的iconfont去找；

另外，Expander旁边的小箭头，网易云是没有的，这里我个人觉得加上要好一些，这个可以看个人需求删除或者保留
