WPF Slider滑动条的颜色修改方法
效果如下：
鄙人虽然开发wpf有些时间，但之前一直是一些简单template和style改改之类的工作，并没有深入研究过。此次为了完成工作，首先也是网上搜了半天，没有找到合适的代码直接拷贝（搜索能力待提高），干脆就直接静下心来琢磨琢磨。
一开始在界面上就放了slider，挠挠头，怎么修改template才能达到效果呢？后来想到了blend，之前一直听说很强大的界面设计工具，但是一直没有用过，就趁此机会就简单运用了一下。blend中很牛逼的就是编辑模板，通过创建模板副本，可以看到slider结构
结合代码发现，thumb左右两边的reapeatbutton的宽度会随着thumb的位置会变化。那问题就变得简单很多，修改左repeatbutton的template就可以达到目的，核心代码如下。
