研究了一天，终于成功在Win7标题栏上加了按钮。
（使用AreoGlass模拟的标题栏）
效果图

废话不多说，代码：

[StructLayout(LayoutKind.Sequential)]        public struct MARGINS        {            public int cxLeftWidth;            public int cxRightWidth;            public int cyTopHeight;            public int cyBottomHeight;        };        [DllImport("DwmApi.dll")]        public static extern int DwmExtendFrameIntoClientArea(            IntPtr hwnd,            ref MARGINS pMarInset);private void Window_Loaded(object sender, RoutedEventArgs e)        {            Background = Brushes.Transparent;            try            {                IntPtr mainWindowPtr = new WindowInteropHelper(this).Handle;                HwndSource mainWindowSrc = HwndSource.FromHwnd(mainWindowPtr);                mainWindowSrc.CompositionTarget.BackgroundColor = Colors.Transparent;                MARGINS margins = new MARGINS();                margins.cxLeftWidth = -1;                margins.cxRightWidth = -1;                margins.cyTopHeight = -1;                margins.cyBottomHeight = -1;                int hr = DwmExtendFrameIntoClientArea(mainWindowSrc.Handle, ref margins);                if (hr < 0)                {                      //未启用AreoGlass                      //在此可以参见[C#标题栏添加按钮]，网上例子很多。                }            }            catch (DllNotFoundException)            {                Application.Current.MainWindow.Background = Brushes.White;                //未启用AreoGlass，同上。            }        }

XMAL：

<Window x:Class="UsersApp.MainWindow"        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"        Title="MainForm" Height="400" Width="500" Loaded="Window_Loaded" Icon="/UsersApp;component/Images/Error.ico" WindowStartupLocation="CenterScreen" WindowStyle="None" MaxWidth="500" MaxHeight="400" MinHeight="400" MinWidth="500">    <Grid Height="378">        <Label Content="主窗体" Height="28" HorizontalAlignment="Left" Name="label1" VerticalAlignment="Top" Margin="-3,-6,0,0" />        <Button Content="" Height="19" HorizontalAlignment="Left" Margin="50,0,0,0" Name="button1" VerticalAlignment="Top" Width="39" />    </Grid></Window>

然后在MainForm上加个Frame之类的控件，模拟用户区。
最后，因为是无边框窗体，所以必须自己写窗体拖动。
这个网上也有很多，自己搜吧。
