如何在后面的代码中使用WPF C＃创建带有图像的自定义MessageBox？

    string messageBoxText = \"Do you want to save changes?\";
    string caption = \"Your caption\";
    MessageBoxButton button = MessageBoxButton.YesNoCancel;
    MessageBoxImage icon = MessageBoxImage.Warning;
    MessageBox.Show(messageBoxText, caption, button, icon);

MyWindow.ShowDialog()

    Window wnd = new Window();
    Grid grid = new Grid();
    wnd.Height = 200;
    wnd.Width = 150;
    grid.RowDefinitions.Add(new RowDefinition {Height = new GridLength(100) });
    grid.RowDefinitions.Add(new RowDefinition {Height = GridLength.Auto });
    wnd.Content = grid;
    Image img = new Image();
    Button btn = new Button();
    btn.Content = \"OK\";
    btn.VerticalAlignment = VerticalAlignment.Bottom;
    Grid.SetRow(img, 0);
    Grid.SetRow(btn, 1); 
    grid.Children.Add(img);
    grid.Children.Add(btn);
    wnd.Owner = MyMainWindow;
    wnd.ShowDialog();

<Window>
 <Grid>
  <Grid.ColumnDefinition Width=\"50\" />
  <Grid.ColumnDefinition Width=\"*\">
  <Label Grid.Column=\"0\" Content=\"Hello World!\" />
 </Grid>
</Window>

public void MakeWin(DependencyObject owner)
{
   MakeWin(Window.GetWindow(owner));
}

public void MakeWin(Window owner)
{
   Window window = new Window();
   Grid grid = new Grid();
   grid.ColumnDefinitions.Add(new ColumnDefinition { Width = new GridLength(50) });
   grid.ColumnDefinitions.Add(new ColumnDefinition {Width = GridLength.Auto});
   window.Content = grid;

   Label label = new Label { Content = \"Hello World!\" };
   Grid.SetColumn(label, 0); // Depandency property
   grid.Children.Add(label);

   window.Owner = owner;
   window.ShowDialog();
}
