请问一个布局

请教一个布局
问题:怎么让¥1右对齐?
最外面是一个StackPanel(spBorder)
垂直布局,上面是图片,下面是文字
下面文字我要让油条左对齐,让¥1右对齐,我又建了一个StackPanel,在里面放了两个TextBlock



StackPanel spBorder = new StackPanel();        //spBorder    
                Image image = new Image(); //spBorder.child1
                image.Source = new BitmapImage(new Uri("images/" + dr["Image_Path"] + "", UriKind.Relative));
                StackPanel spBreakfast = new StackPanel();        //spBorder.child2   
                spBreakfast.Orientation = Orientation.Horizontal;
                TextBlock tb1 = new TextBlock();
                tb1.Text = dr["Dish_Name"].ToString();
                tb1.FontSize = 20;
                //TextBlock tb3 = new TextBlock();
                //tb3.Text = "            ";
                TextBlock tb2 = new TextBlock();
                tb2.Text = "¥" + dr["Price"];
                tb2.FontSize = 20;
                tb2.Foreground = Brushes.Red;
                spBreakfast.Children.Add(tb1);
                //spBreakfast.Children.Add(tb3);
                spBreakfast.Children.Add(tb2);
                spBorder.Children.Add(image);
                spBorder.Children.Add(spBreakfast);
------解决思路----------------------
用textbox  不允许编辑   这控件好像有那个属性
