　　　using System.Threading;

  　　先定义委托　线程

    　 Thread myThread;
        private delegate  void myDelegate(string r, string str);//定义委托

 

2

　　　窗体载入时添加列
        private void Form1_Load(object sender, EventArgs e)
        {
            this.dataGridView1.Columns.Add("ad", "ad");//添加列
        }

3  

     private void button1_Click(object sender, EventArgs e)
        {
            myThread= new Thread(startFillDv);//实例化线程
            myThread .Start();//启动线程
        }

     private void startFillDv()
        {

           for (int i =0;i<=50000;i++)
           {
               Grid(i.ToString(), i.ToString());
               Thread.Sleep(1000);//干这么久，休息下的
           }
           
        }

        private void Grid(string s,string sa)
        {
       
            if (this.InvokeRequired)
            {

                this.Invoke(new myDelegate(Grid), new object[] { s, sa });
            }
            else
