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

                if (!ht.ContainsValue(val))
                { ht.Add(key, val); key++; }
            }

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

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

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 

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();}}}
