一．前言
申明：WPF自定义控件与样式是一个系列文章，前后是有些关联的，但大多是按照由简到繁的顺序逐步发布的等，若有不明白的地方可以参考本系列前面的文章，文末附有部分文章链接。

二．自定义Window窗体样式
自定义的Window窗体效果：
因为WPF默认的窗体比较简陋，大都需要自己实现Window窗体样式效果，基本思路很简单：
这样从外观样式上可以满足，但做为窗体该具备的基本功能还没有，需要另外来实现了：
- 窗体Icon、标题栏（可以通过样式实现）；
- 窗体的基本按钮：最小化、最大化、关闭按钮；
- 窗体的鼠标拖动；
- 好像Win8、Win10的功能吧，窗体拖动到桌面边缘自动最大化、还原；
- 鼠标调整窗口大小；
- 双击标题栏最大化、还原；
上面的功能在本文中，一部分是自定义实现的，还有一部分是用了一个开源库（Microsoft.Windows.Shell）用于实现窗体大小、拖放等窗体基本功能，Microsoft.Windows.Shell文件下载：点我下载。
进入正题，自定义窗体WindowBase的后台C#代码：

get { return (string)GetValue(FIconProperty); }
set { SetValue(FIconProperty, value); }

DependencyProperty.Register("FIconSize", typeof(double), typeof(WindowBase), new PropertyMetadata(20D));
