获取矩形垂直堆叠到水平，但保持形状

Question

我输入正确完成我的所有矩形垂直堆叠，每次绘制一个新的矩形时有不同的颜色，但我努力让输出看起来像底部的图片。请任何人帮助我走上正确的道路。

//List to strore all randomly generated rectangles 
    List<Rectangle> rectangleCollection = new List<Rectangle>(); 
    //Counts the amount of time a rectangle needs to be drawn 
    int count = 0; 

    public static Random ran = new Random(); 

    void CreateRectangle() 
    { 
     int TallestRectangle = 0; ; 


     int PrevRecY = 0; 

     Graphics graphic = pictureBox1.CreateGraphics(); 
     SolidBrush brush; 

     foreach (Rectangle rect in rectangleCollection) 
     { 
      if (rect.Height > TallestRectangle) 
       TallestRectangle = rect.Height; 
     } 

     foreach (Rectangle rect in rectangleCollection) 
     { 
      graphic.FillRectangle(brush = new SolidBrush(Color.FromArgb(ran.Next(1, 255), ran.Next(1, 255), ran.Next(1, 255))), 
       new Rectangle(rect.X + PrevRecY, (TallestRectangle - rect.Height), rect.Width, rect.Height)); 

      PrevRecY += rect.Width; 
     } 
    } 

    private void button1_Click(object sender, EventArgs e) 
    { 
     count = int.Parse(textBox1.Text); 
     for (int i = 0; i < count; i++) 
     { 
      GetRandomRectangle(); 
     } 
     CreateRectangle(); 
    } 

    void GetRandomRectangle() 
    { 
     Graphics graph = this.CreateGraphics(); 
     int x = 0; 
     int y = 0; 

     int width = ran.Next(20, 100); 
     int height = ran.Next(30, 150); 

     Rectangle rec1 = new Rectangle(x, y, width, height); 
     rectangleCollection.Add(rec1); 
    }

对于每个矩形，责令最短至最高，

• 作出这样的高度的横长方形，从比更高所有矩形的左边开始，在右边结束所有矩形的权利。

每当您创建一个水平矩形时，将它放置在最低水平矩形的顶部（按照水平位置），您正在创建一个水平矩形。
