在UWP中自定义半边框样式的输入框

Windows10发布已经有一阵子了，已经有一些公司上架了自己的UWP应用程序，为WindowsStore增添光彩。已经安装Windows10的用户也或多或少的安装了一些UWP的应用程序，针对这些UWP的应用程序设计来说有好有坏，好的方面体现在它们的用户体验始终是保证一致，符合Win10的产品理念，步调能够保持一致；坏的方面就是由于它们步调太过于一致导致用户体验太过雷同，进而出现一些用户会出现审美疲劳。这个博主可以理解理解，毕竟UWP应用才推出不久，接触的人也不是很多，关键一点，生态圈也很羸弱，所以没办法，或许暂时还没办法达到与Android和IPhone那样好的用户体验，但既然已入坑.NET ，那我不入地狱谁入地狱呀：)？作为.NET开发人员，那就努力写些一些漂亮的UI控件，在这个小米加步枪的开发时代里多做一个事情，希望能够为后来的开发者提供一个好的生态环境（程序猿，情怀都是骗别人的，你信吗？）。在这篇博文中，博主为新手朋友们介绍一下如何在XAML中通过对控件的样式设置来实现带半边框样式的输入框。

谈到输入框，很多朋友都会想到TextBox控件。没错，一个很不错的选择。那如何设置它的边框为半边框的样式呢？有点开发经验的朋友或许会想到通过使用LinearGradientBrush来设置TextBox的BorderBrush。好那我们就先试一下，看符合我们的要求不，代码贴上：

<TextBox Grid.Row="0"  VerticalAlignment="Center" Margin="12,0,12,0">
<TextBox.BorderBrush>
<LinearGradientBrush EndPoint="1,1" StartPoint="1,0">
<GradientStop Color="Transparent" Offset="0"/>
<GradientStop Color="Transparent" Offset="0.75"/>
<GradientStop Color="Green" Offset="0.75"/>
<GradientStop Color="Green" Offset="1"/>
</LinearGradientBrush>
</TextBox.BorderBrush>
</TextBox>

来，运行起来看看效果：

效果图如下所示：



写到这里，发现它已经差不多了吧，不知你是否对它满意？？？！！！

故意把后两部分代码折叠起来，因为有点小长，所以怕新手朋友们看完后鄙视我。其实你要是能看懂第二中的样式的话，第三中就不在话下了！

好了，现在已经很晚了，该去洗澡睡觉了！

代码有点小乱就不上传了，感兴趣的朋友可以自行Coding！
