c# - 如何使无边框仅在边框顶部的拖动中正常化

Question

当你像在浏览器上一样将它拖到顶部时，我如何使我的无边界表单正常化，我曾尝试过这个

 private void Window_MouseDown(object sender, MouseButtonEventArgs e)
    {
        if (e.LeftButton == MouseButtonState.Pressed)
        {
            DragMove();

         //   if (WindowState == System.Windows.WindowState.Maximized)

           //     WindowState = System.Windows.WindowState.Normal;

        }
    }

但是无论你在哪里点击表格，它都会一直正常化

Answer 1

您可以通过在表单顶部制作一个透明标签来实现这一点，然后使用它

private void label_MouseDown(object sender, MouseButtonEventArgs e)
{
if (e.LeftButton == MouseButtonState.Pressed)
{
    DragMove();

    if (WindowState == System.Windows.WindowState.Maximized)

        WindowState = System.Windows.WindowState.Normal;

}
}
