利用线程显示数据

Question

我在读取数据库的数据的时候，因为数据量不少，所以程序会有稍稍的卡死，然后一下子显示出来了，现在我想利用线程来控制数据的显示，就是读取到哪里就显示出多少，既有动态的效果，程序又不会卡死，请问这个如何实现啊

    class Program
    {
        static void Main(string[] args)
        {
            MyMainThread mainThread = new MyMainThread(); 
            mainThread.Test(); 
            //Thread thread = new Thread(new ThreadStart(mainThread.Test)); 
            //thread.Start(); 
            
            MyThreadDemo domethread = new MyThreadDemo();
            domethread.Run();            while (true)
            {
                ;
            }        }      
    }     class MyMainThread 
    {
        
        public void Test() 
        { 
            MyThreadWrapper wrapper = new MyThreadWrapper(GetDataAfterMyThread);
            Thread thread = new Thread(new ThreadStart(wrapper.DoMyThread));
            thread.Start();             while (thread.IsAlive)
            {
                ;
            }            Thread.CurrentThread.Join(100); 
            Console.WriteLine("主线程:我接着进行……"); 
            for (int i = 0; i < 10; i++) 
            { 
                Thread.CurrentThread.Join(100); 
                Console.WriteLine("主线程:" + i.ToString()); 
            } 
        }         void GetDataAfterMyThread(object data) 
        { 
            Console.WriteLine(data.ToString()); 
            Console.WriteLine("主线程:收到了子线程的通知！"); 
        } 
    }

上面的那个少发了,以这个为准吧,win32控制台程序    class Program
    {
        static void Main(string[] args)
        {
            MyMainThread mainThread = new MyMainThread(); 
            mainThread.Test();
            Thread thread = new Thread(new ThreadStart(mainThread.Test));
            thread.Start(); 
            while (true)
            {
                ;
            }        }      
    }     class MyMainThread 
    {
        
        public void Test() 
        { 
            MyThreadWrapper wrapper = new MyThreadWrapper(GetDataAfterMyThread);
            Thread thread = new Thread(new ThreadStart(wrapper.DoMyThread));
            thread.Start();             while (thread.IsAlive)
            {
                ;
            }            Thread.CurrentThread.Join(100); 
            Console.WriteLine("主线程:我接着进行……"); 
            for (int i = 0; i < 10; i++) 
            { 
                Thread.CurrentThread.Join(100); 
                Console.WriteLine("主线程:" + i.ToString()); 
            } 
        }         void GetDataAfterMyThread(object data) 
        { 
            Console.WriteLine(data.ToString()); 
            Console.WriteLine("主线程:收到了子线程的通知！"); 
        } 
    } 
    
    class MyThreadWrapper 
    { 
        public delegate void DelegateDoAfterFinish(object data);  
        DelegateDoAfterFinish DoAfterFinish = null; 
        public MyThreadWrapper() 
        { 
        } 
        public MyThreadWrapper(DelegateDoAfterFinish d) 
        { 
            DoAfterFinish = d; 
        } 
        public void DoMyThread() 
        { 
            Console.WriteLine("子线程：我正在做些事情！"); 
            Thread.CurrentThread.Join(1000);             if (DoAfterFinish != null) 
            { 
                DoAfterFinish("子线程：OK,我做完啦！"); 
            } 
        }        public void DoMyThread(object i)
        {
            Console.WriteLine("子线程：我正在做些事情！");
            Thread.CurrentThread.Join(1000);            i = 100;
            if (DoAfterFinish != null)
            {
                DoAfterFinish("子线程：OK,我做完啦！" + i.ToString());
            }
        } 
    }

        //委托
        public delegate void SetTextCallback(string text);        //显示状态（ListBox）
        private void SetText(string text)
        {
            if (this.listBoxStatus.InvokeRequired)
            {
                SetTextCallback d = new SetTextCallback(SetText);
                this.Invoke(d, new object[] { text });
            }
            else
            {
                this.listBoxStatus.Items.Add(text);
                this.listBoxStatus.SelectedIndex = this.listBoxStatus.Items.Count - 1;
            }        //你的程序按钮事件
        private void button1_Click(object sender, EventArgs e)
        {
            Thread thread1 = new Thread(new ThreadStart(MyWorkThread));
            thread1.Start();
        }        //线程调用的函数
        public void MyWorkThread(object p1)
        {
            //你要干的事
            //......
            SetText("你要显示的进度");
            //......
            return;       
        }
