Answer 1

Google对此充满了答案：

private void ToolBar_Loaded(object sender, RoutedEventArgs e)
{
    ToolBar toolBar = sender as ToolBar;
    var overflowGrid = toolBar.Template.FindName("OverflowGrid", toolBar) as FrameworkElement;
    if (overflowGrid != null)
    {
            overflowGrid.Visibility = Visibility.Collapsed;
    }

    var mainPanelBorder = toolBar.Template.FindName("MainPanelBorder", toolBar) as FrameworkElement;
    if (mainPanelBorder != null)
    {
        mainPanelBorder.Margin = new Thickness(0);
    }
}

并将此方法分配给工具栏的Loaded事件。
