C# 如何在Silverlight中创建动态画布的边框？

您好，我正在代码隐藏中创建画布，如下所示：

Canvas musicPlayerCanvas = new Canvas();
                    musicPlayerCanvas.Background = new SolidColorBrush(Colors.White);
                    musicPlayerCanvas.Height = 80;
                    musicPlayerCanvas.Width = 1018;
LayoutRoot.Children.Add(musicPlayerCanvas);

musicPlayerCanvas.Children.Add(playingText);
musicPlayerCanvas.Children.Add(albumImage);

Border myBorder = new Border();
                    //Border Proporties



                    Canvas.SetTop(musicPlayerCanvas, 26);
                    Canvas.SetLeft(musicPlayerCanvas, 154);
                    LayoutRoot.Children.Add(musicPlayerCanvas);
                    myBorder.Child = musicPlayerCanvas;

现在我如何从codebehind向画布添加边框

我尝试创建边框并指定子对象，如下所示：

Canvas musicPlayerCanvas = new Canvas();
                    musicPlayerCanvas.Background = new SolidColorBrush(Colors.White);
                    musicPlayerCanvas.Height = 80;
                    musicPlayerCanvas.Width = 1018;
LayoutRoot.Children.Add(musicPlayerCanvas);

musicPlayerCanvas.Children.Add(playingText);
musicPlayerCanvas.Children.Add(albumImage);

Border myBorder = new Border();
                    //Border Proporties



                    Canvas.SetTop(musicPlayerCanvas, 26);
                    Canvas.SetLeft(musicPlayerCanvas, 154);
                    LayoutRoot.Children.Add(musicPlayerCanvas);
                    myBorder.Child = musicPlayerCanvas;

这对我不起作用。请帮忙

谢谢，

您希望将画布添加到边框，如下所示：

Canvas musicPlayerCanvas = new Canvas();
musicPlayerCanvas.Background = new SolidColorBrush(Colors.Purple);

Border border = new Border();
border.BorderBrush = new SolidColorBrush(Colors.Black);
border.BorderThickness = new Thickness(5);
border.Height = 80;
border.Width = 1018;
border.Child = musicPlayerCanvas;

LayoutRoot.Children.Add(border);

另一方面，当使用文本框和图像等控件时（我认为您可能正在查看控件名称），您可能希望使用网格而不是画布作为容器控件。 干杯
