用WPF做贪吃蛇小游戏时，发现了一个问题：
贪吃蛇的移动，我是通过不断刷新Rectangle来实现(贪吃蛇的身体由一组Rectangle组成),因此需要不断调整Rectangle的坐标，但是WPF中没有Location的相关设置
在网上查到可以用Thickness实现
Rectangle Rec = new Rectangle(); Rec.Margin = new Thickness(1, 2, 3, 4);
但总是调不准
其实可以通过Canvas实现
用代码实现Canvas:
// Create the application‘s main window mainWindow = new Window (); mainWindow.Title = "Canvas Sample"; // Create the Canvas myParentCanvas = new Canvas(); myParentCanvas.Width = 400; myParentCanvas.Height = 400; // 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; myCanvas2.Height = 100; myCanvas2.Width = 100; Canvas.SetTop(myCanvas2, 100); Canvas.SetLeft(myCanvas2, 100); myCanvas3 = new Canvas(); myCanvas3.Background = Brushes.Blue; myCanvas3.Height = 100; myCanvas3.Width = 100; Canvas.SetTop(myCanvas3, 50); Canvas.SetLeft(myCanvas3, 50); // Add child elements to the Canvas‘ Children collection myParentCanvas.Children.Add(myCanvas1); myParentCanvas.Children.Add(myCanvas2); myParentCanvas.Children.Add(myCanvas3); // Add the parent Canvas as the Content of the Window Object mainWindow.Content = myParentCanvas; mainWindow.Show ();
也可以通过添加Canvas控件来实现，添加之后
Rectangle Rec = new Rectangle(); Canvas.SetLeft(Rec, posX); Canvas.SetTop(Rec, posY); 你添加的canvas名字.Children.Add(Rec);
