一：通过操作GDI+的不合理的解决方案
数字在不断变换的时候重绘    基本上都会让程序当掉
或许是我的程序没写好，希望达人指教

Code

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

namespace lottery
{
 public partial class Form1 : Form
 {
 private int[] arr = new int[7];
 private Font font = new Font("Arial Black", 36);
 private Brush brush;
 private RectangleF rec = new RectangleF(0, 13, 100, 100);
 private StringFormat sf = new StringFormat();
 private Control[] controls; 
 private bool flag = true;
 public Form1()
 {
 InitializeComponent(); 
 }
 private void Form1_Load(object sender, EventArgs e)
 {
 controls = new Control[] { num1, num2, num3, num4, num5, num6,num7 };
 for (int i = 0; i < 7; i++)
 {
 controls[i].Paint+=new PaintEventHandler(num_Paint);
 }
 sf.Alignment = StringAlignment.Center;
 }
 private void button1_Click(object sender, EventArgs e)
 {
 if (button1.Text == "stop")
 {
 flag = false;
 }
 if (button1.Text == "start") 
 {
 button1.Text = "stop";
 while (flag)
 {
 start();
 }
 } 
 }
 /// <summary>
 /// 开始
 /// </summary>
 private void start()
 {
 MakeNums();
 for (int i = 0; i < 7; i++)
 {
 if (i == 6)
 {
 brush = new SolidBrush(Color.Blue);
 }
 else
 {
 brush = new SolidBrush(Color.Red);
 }
 Graphics draw = Graphics.FromHwnd(controls[i].Handle);
 draw.Clear(Color.Black);
 draw.DrawString(arr[i].ToString(), font, brush, rec, sf);
 draw.Dispose();
 }
 }
 /// <summary>
 /// 制造号码
 /// </summary>
 private void MakeNums()
 {
 Random rand = new Random();
 Hashtable ht = new Hashtable(); 
 //产生不重复的随机数
 int key = 0;
 while (ht.Count <= 6)
 {
 int val = rand.Next(1, 33);
 if (!ht.ContainsValue(val))
 { ht.Add(key, val); key++; }
 }
 //得到随机数
 for (int i = 0; i < 6; i++)
 {
 arr[i] = (int)ht[i];
 }
 //冒泡排序
 int temp;
 for (int outer = 5; outer >= 0; outer--)
 {
 for (int inner = 0; inner <= outer - 1; inner++)
 {
 if (arr[inner] > arr[inner + 1])
 {
 temp = arr[inner];
 arr[inner] = arr[inner + 1];
 arr[inner + 1] = temp;
 }
 }
 }
 //制造蓝色球
 arr[6] = rand.Next(1, 16);
 }
 /// <summary>
 /// 重绘事件
 /// </summary>
 /// <param name="sender"></param>
 /// <param name="e"></param>
 private void num_Paint(object sender, PaintEventArgs e)
 {
 if (arr == null) { return; }
 PictureBox pb = (PictureBox)sender;
 int num = Convert.ToInt32(pb.Name.Replace("num", ""))-1;
 Graphics draw = e.Graphics;
 draw.Clear(Color.Black);
 if (num == 6)
 {
 brush = new SolidBrush(Color.Blue);
 }
 else
 {
 brush = new SolidBrush(Color.Red);
 }
 draw.DrawString(arr[num].ToString(), font, brush, rec, sf);
 }
 }
}

二：通过Invoke方法把控件实例传入到程序中操作的更合理的方法

Code

   
   using System;
using System.Collections;
using System.Collections.Generic;
using System.ComponentModel;
using System.Threading;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace lottery
{
 public partial class Form1 : Form
 {
 private bool flag = true;
 delegate void SetTextDelegate(Label label,string text);
 private Label[] labels;
 private Font font;
 public Form1()
 {
 InitializeComponent(); 
 }
 /// <summary>
 /// 制造号码
 /// </summary>
 private int[] MakeNums()
 {
 int[] arr = new int[7];
 Random rand = new Random();
 Hashtable ht = new Hashtable(); 
 //产生不重复的随机数
 int key = 0;
 while (ht.Count <= 6)
 {
 int val = rand.Next(1, 33);
 if (!ht.ContainsValue(val))
 { ht.Add(key, val); key++; }
 }
 //得到随机数
 for (int i = 0; i < 6; i++)
 {
 arr[i] = (int)ht[i];
 }
 //冒泡排序
 int temp;
 for (int outer = 5; outer >= 0; outer--)
 {
 for (int inner = 0; inner <= outer - 1; inner++)
 {
 if (arr[inner] > arr[inner + 1])
 {
 temp = arr[inner];
 arr[inner] = arr[inner + 1];
 arr[inner + 1] = temp;
 }
 }
 }
 //制造蓝色球
 arr[6] = rand.Next(1, 16);
 return arr;
 }

 private void button1_Click(object sender, EventArgs e)
 {
 if (button1.Text == "start")
 {
 flag = true;
 button1.Text = "stop";
 ThreadStart TStart = new ThreadStart(Start);
 Thread thread = new Thread(TStart);
 thread.Start();
 }
 else
 {
 flag = false;
 button1.Text = "start";
 }
 }
 private void Start()
 {
 while (flag)
 { PrintNum(); Thread.Sleep(88); } 
 }
 private void PrintNum()
 {
 int[] arr = MakeNums();
 for (int i = 0; i < 7; i++)
 {
 SetTextDelegate mydelegate = new SetTextDelegate(SetText);
 try { Invoke(mydelegate, labels[i], arr[i].ToString()); }
 catch { return; }
 }
 }
 private void SetText(Label label, string text)
 { 
 label.Text = text;
 label.TextAlign = ContentAlignment.MiddleCenter;
 label.Font = font;
 if (label.Name == "label7")
 { label.ForeColor = Color.Blue; }
 else
 { label.ForeColor = Color.Red; }
 }

 private void Form1_Load(object sender, EventArgs e)
 {
 labels = new Label[] { label1, label2, label3, label4, label5, label6, label7 };
 font = new Font("Arial Black",36);
 }
 
 }
}

三：用到了timer控件和list的sort方法的  第三种解决方案

 

Code
using System;
using System.Collections.Generic;
using System.Windows.Forms;

namespace SS
{
    public partial class Form_SS : Form
    {
        private Label[] cs = null;
        public Form_SS()
        {
            InitializeComponent();
            cs = new Label[] { label1, label2, label3, label4, label5, label6, label7 };
        }

        private List<int> Create()
        {
            List<int> t = new List<int>();
            Random ran = new Random(unchecked((int) DateTime.Now.Ticks));
            for (int i = 0, n = ran.Next(1, 34); i < 6; i++)
            {
                while (t.Exists(delegate(int item) { return item == n; })) n = ran.Next(1, 34);
                t.Add(n);
            }
            t.Sort();
            t.Add(ran.Next(1, 17));
            return t;
        }

        private void btn_Start_Click(object sender, EventArgs e)
        {
            btn_Start.Text = (timer1.Enabled = !timer1.Enabled) ? "stop" : "start";
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            List<int> t = Create();
            for (int i = 0; i < t.Count; i++) cs[i].Text = t[i].ToString();
        }
    }
}

四：通过程序创建窗体的更简单的代码 

Code
class Program{static Random r = new Random();
static void Main(string[] args){
Form f = new Form { Text="xxxx" };
Button b = new Button { Text = "start", Top=50 };
b.Click += delegate(object sender, EventArgs e) { ((Button)sender).Text = ((Button)sender).Text == "stop" ? "start" : "stop"; Do(f); };
f.Controls.AddRange(new Control[] { b,new Label{ AutoSize = true} });
f.ShowDialog();}static void Do(Form f){
    while (f.Controls[0].Text == "stop"){
    List<int> ns = new List<int>();
    while (ns.Count != 6) { ns.Add(new Func<int, int>(delegate(int t) { while (ns.Contains(t = r.Next(1, 34))); return t;})(1)); }
    ns.Sort();
    f.Controls[1].Text = string.Format("{0} - {1} - {2} - {3} - {4} - {5} = {6}",ns[0],ns[1],ns[2],ns[3],ns[4],ns[5], r.Next(1,17));
    Application.DoEvents();}}}
