这跟WPF的System.Windows.MessageBox.Show的工作方式一样，会自动继承owner的Topmost。 This works the same way as WPF's System.Windows.MessageBox.Show, which automatically inherits the owner's Topmost.

Test code:

        private void NormalButton_Click(object sender, RoutedEventArgs e)
        {
            Topmost = false;
            MessageBox.Show(this, "MessageBox will not be Topmost");
        }

        private void TopmostButton_Click(object sender, RoutedEventArgs e)
        {
            Topmost = true;
            MessageBox.Show(this, "MessageBox will be Topmost");
        }
