wpf之windows设置WindowStyle为None

设置无窗口边框：

AllowsTransparency="True"

设置窗口可以拖动

增加事件：

 处理方法如下：

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            this.MouseDown += delegate { DragMove(); };
        }

设置可以改变大小

   <WindowChrome.WindowChrome>
        <WindowChrome GlassFrameThickness="0" ResizeBorderThickness="4" CaptionHeight="0" CornerRadius="0" />
    </WindowChrome.WindowChrome>
