推荐答案

如果您特别想禁用在窗口标题栏上单击鼠标右键显示系统上下文菜单，则可以处理

If you specifically want to disable showing system context menu on right click on window's title bar, you can handle WM_CONTEXTMENU:

const int WM_CONTEXTMENU = 0x007B;
protected override void WndProc(ref Message m)
{
    if (m.Msg == WM_CONTEXTMENU)
        m.Result = IntPtr.Zero;
    else
        base.WndProc(ref m);
}

如果您还希望避免单击表单图标以显示上下文菜单的可能性，则可以设置

If you also want to prevent the possibility of clicking on form's icon to show the context menu, then you can set ShowIcon property of the form to false:

this.ShowIcon = false;
