WPF仿网易云音乐系列（二、歌单创建窗口+登录设置模块）
老衲牺牲午休时间写博客，都快把自己感动了，-_-!!
之前上一篇随笔，我看了下评论，有部分人说WPF已经凉凉了，这个我觉得，这只是一个达到自己目的的工具而已，只要自己能用这个工具，得心应手的做出自己想要的东西就行，关心工具本身凉了没，个人觉得没啥意义；另外，我一个做Java的都没泼凉水，你.Net自己的东西，你们还不满意了，太过分了，haha；
以上，瞎bb一通，轻喷...下面开始正题；
一.简介
上一篇文章，咱们利用Expander+RadioButton实现了左侧菜单栏（或者是导航栏），这一片随笔，做创建歌单窗口和登录设置按钮那一坨...咱们先来看看原版长啥样子
看上去蛮厉害的样子，咱们开始搞一搞；
二.正文
创建歌单窗口
首先需要创建一个窗口。。然后设置WindowStyle="None" 使窗口无边框化；另外，窗口在弹出的时候，是有一个蒙版效果的；这里咱们还需要给他加上蒙版；话不多说，上代码；

}
最后，效果如下：

登录设置模块
这一块呢，就比较简单了，主要就一个面板上放三个按钮；当然，都是自定义按钮；然后再设置个border就搞定；代码如下：
<Border Background="White" BorderThickness="0,0.3,0,0" BorderBrush="{StaticResource LineColor}"
VerticalAlignment="Bottom" Width="160" Height="60" HorizontalAlignment="Left"
Grid.ColumnSpan="2" Margin="0,0,0,0.4">
<StackPanel Orientation="Horizontal">
<Button Style="{StaticResource UserLoginButton}" Width="90">Michael</Button>
<local:FButton FIcon="" Margin="3" Style="{StaticResource FButton_Transparency}" HorizontalAlignment="Right"
></local:FButton>
<local:FButton FIcon="" Margin="3" Style="{StaticResource FButton_Transparency}" HorizontalAlignment="Right"
></local:FButton>
</StackPanel>
</Border>
自定义按钮：
<Style x:Key="UserLoginButton" TargetType="Button">
<Setter Property="Template" >

最后，效果如下：
咳咳，这个就不好意思再说 “还原度百分之百” 了，主要是没有专门去找后边两个按钮的图标，直接拿到手上现有的就用了；以上就是此篇文章的全部内容，请批评指正；
