Question

我想在矩形中添加文本块或标签，后面是使用代码创建的任何人都可以帮助我吗？

  for (int i = 0; i < _RoomX.Count; i++)
        {
            _RoomX[i] = (Convert.ToDouble(_RoomX[i]) * 20).ToString();
            _RoomY[i] = (Convert.ToDouble(_RoomY[i]) * 20).ToString();

            var rectangle = new Rectangle()
            {

                Stroke = Brushes.Black,
                Fill = brush,
                Width = Convert.ToDouble(_RoomX[i]),
                Height = Convert.ToDouble(_RoomY[i]),
                Margin = new Thickness(
                    left: 15,
                    top: 50,
                    right: 0,
                    bottom: 0),
                HorizontalAlignment = HorizontalAlignment.Left,
                VerticalAlignment = VerticalAlignment.Top

            };
            mainCanvas.Children.Add(rectangle);
        }

井矩形不是从形状对象派生的内容控件...我们不能将它用作面板。

而不是矩形，你可以使用边框..

如果您的要求需要矩形，那么您可以做的是...创建网格＆gt;然后将矩形添加到该网格＆gt;并创建一个文本块并将其添加到同一网格...因为网格在物理上不可见，所以看起来像文本添加到矩形..

编辑：以下代码将帮助您更好地理解

for (int i = 0; i < _RoomX.Count; i++)
        {
            _RoomX[i] = (Convert.ToDouble(_RoomX[i]) * 20).ToString();
            _RoomY[i] = (Convert.ToDouble(_RoomY[i]) * 20).ToString();

            var rectangle = new Rectangle()
            {

                Stroke = Brushes.Black,
                Fill = brush,
                Width = Convert.ToDouble(_RoomX[i]),
                Height = Convert.ToDouble(_RoomY[i]),
                Margin = new Thickness(
                    left: 15,
                    top: 50,
                    right: 0,
                    bottom: 0),
                HorizontalAlignment = HorizontalAlignment.Left,
                VerticalAlignment = VerticalAlignment.Top

            };

            Grid grid = new Grid();
            grid.Children.Add(rectangle);
            TextBlock textblock = new TextBlock();
            textblock.Text = "Text to add";
            grid.Children.Add(textblock);

            mainCanvas.Children.Add(grid);
        }
