我是自学成才的，正在尝试从基于文本的程序转向实际的游戏和应用程序，但我无法弄清楚/理解 Microsoft 的文档来创建画布。当我运行这段代码时，我得到的只是终端。这是我当前的代码，直接从 Microsoft 复制：

using System.ComponentModel;
using System.Threading.Tasks;

            // Define child Canvas elements
            myCanvas1 = new Canvas();
            myCanvas1.Background = Brushes.Red;
            myCanvas1.Height = 100;
            myCanvas1.Width = 100;
            Canvas.SetTop(myCanvas1, 0);
            Canvas.SetLeft(myCanvas1, 0);

            myCanvas2 = new Canvas();
            myCanvas2.Background = Brushes.Green; …
