读心术动态加载控件遇到的问题
读心术动态加载图片和控件，但是点击button按钮却无法实现图片刷新，再者如何实现是9的倍数的图片加载的都相同？



using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace _111
{
  public partial class Form1 : Form
  {
  public Form1()
  {
  InitializeComponent();
  }

  private void Form1_Load(object sender, EventArgs e)
  {
  Button myButton = new Button();
  myButton.Text = "重试";
  myButton.Height = 40;
  myButton.Width = 60;
  myButton.Top = 15;
  myButton.Left = 100;
  myButton.Click += new EventHandler(myButton_Click);
  this.Controls.Add(myButton);

  }
  private void myButton_Click(object sender,EventArgs e)
  {
  Random myRandom = new Random();
  int top = 60, left = 60;
  int top1 = 100, left1 = 75;
  Label[] myLabel = new Label[10];
  int s = 1;
  PictureBox[] myPicturebox = new PictureBox[10];
  for (int i = 0; i < 10; i++)
  {
  for (int j = 0; j < 10; j++)
  {  
  myPicturebox[j] = new PictureBox();//初始化picturebox的新实例
  myPicturebox[j].Image = System.Drawing.Bitmap.FromFile(@"icon\" + myRandom.Next(1, 40) + ".bmp");
  myPicturebox[j].Width = 40;
  myPicturebox[j].Height = 40;
  myPicturebox[j].Top = top;
  myPicturebox[j].Left = left;
  this.Controls.Add(myPicturebox[j]);
  left += 60;
  string str = s.ToString();
  myLabel[j] = new Label();//初始化类的新实例  
  myLabel[j].Text = str;
  myLabel[j].Width = 40;
  myLabel[j].Height = 20;
  myLabel[j].Top = top1;
  myLabel[j].Left = left1;
  this.Controls.Add(myLabel[j]);
  left1 += 60;
  s = s + 1;
  }
  top1 += 60;
  left1 = 75;
  top += 60;
  left = 60;

  }
  }
   

  }
}

------解决方案--------------------
问题还未解决么？ Random 声明不应该放在button里面 程序只new一次Random 就够了 new多了会出乱子
