在 WPF 窗口中完全删除标题栏的上下文菜单

I have created a WPF Window and set its Window Style property to 'None'. Yet when I press Alt+Up Key combination, a context menu appears on the top left of the Window.

有没有办法也禁用它..

注意：处理 PreviewKeyDown 事件可以完成这项工作，但我正在寻找不同的方法。

   <Window

    x:Class="WpfApplication14.MainWindow"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    WindowStyle="None"

    Title="MainWindow" Height="350" Width="525">

      <Grid/>

    </Window>

在代码后面添加以下代码将清除标题栏的样式并阻止系统菜单：

    private const int GWL_STYLE = -16; //WPF's Message code for Title Bar's Style 
    private const int WS_SYSMENU = 0x80000; //WPF's Message code for System Menu
    [DllImport("user32.dll", SetLastError = true)]
    private static extern int GetWindowLong(IntPtr hWnd, int nIndex);
    [DllImport("user32.dll")]
    private static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);

    // Handling the Messages in Window's Loaded event

    private void Window_Loaded(object sender, RoutedEventArgs e)
    {
        var hwnd = new WindowInteropHelper(this).Handle;
        SetWindowLong(hwnd, GWL_STYLE, GetWindowLong(hwnd, GWL_STYLE) & ~WS_SYSMENU);
    }
