How to draw a rectangle with a background color in WPF
提问by Debhere
Hi I want to have a rectangle like the below picture to fill the entire canvas with different sizes and at different position scatter through out the canvas. My solution environment is WPF C#
嗨，我想要一个像下图这样的矩形来填充整个画布，使其具有不同的大小和不同的位置，分散在画布中。我的解决环境是WPF C#
Could some one please guide me of how to do it? Till now what I have done is canvas_loaded
有人可以指导我如何做吗？到目前为止我所做的是 canvas_loaded
Rectangle rect = new Rectangle();
rect.Fill = new SolidColorBrush(Colors.Black);
rect.Width = 100;
rect.Height = 100;
rect.Stroke = new SolidColorBrush(Colors.Black);
But the problem here how will I position it to the different locaion of the canvas, the size and width I can provide at run time with different value but I need to position the rectangles (Square) at diffrent XY co-ordinates so that none of the rectangles or Squares overlapp each other.
但是这里的问题是我将如何将它定位到画布的不同位置，我可以在运行时提供不同值的大小和宽度，但我需要将矩形（方形）定位在不同的 XY 坐标处，以便没有矩形或正方形相互重叠。
Please help.
请帮忙。

You can use
您可以使用
Canvas.SetLeft(rect, <offset>) Canvas.SetRight(...), Canvas.SetTop(...), Canvas.SetBottom(...)
to position UIElement in the Canvas container.
在 Canvas 容器中定位 UIElement。

Use Random class to generate the xy co-ordinates
使用 Random 类生成 xy 坐标
Random r=new Random();
r.Next(1,100);
