Socket接收数据并绑定给Gridview

Question

web程序不能这么写的。得客户端轮询。你这样只会把服务器搞死的。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using System.Text;
namespace Webtestdatagridview
{
    public partial class _Default : System.Web.UI.Page
    {
        public static int i = 0;
        public static int j = 0;
        private delegate void ShowMsg(string strMsg);
        private ShowMsg SM;
        static  DataTable dt = new DataTable();
        protected void Page_Load(object sender, EventArgs e)
        {
            if (j == 0)
            {
                 dt.Columns.Add("yvalue", typeof(string));
                dt.Rows.Add();
                j++;
            }
            SM += new ShowMsg(SetLabel);
            
        }
        private void SetLabel(string strMsg)
        {            GridView1.DataSource = dt;
            GridView1.DataBind();
        }
        void tsetD(int m)
        {
            int i= 0;
            while (i<10)
            {
                if (m == 0)
                {
                    string  st = "dssd"; 
                    dt.Rows.Add();
                    dt.Rows[dt.Rows.Count - 1][0] = st;                    SM(st);
                    i++;
                }
                else if (m == 1)
                {
                    string st = "aaaa";
                    dt.Rows.Add();
                    dt.Rows[dt.Rows.Count - 1][0] = st;
                    SM(st);
                    i++;
 
                }     
            }
        }        protected void Button1_Click(object sender, EventArgs e)
        {
            this.tsetD(i);
            i++;
        }    }
}
我模拟了一下你想达到的效果，是可以实时更新的、、、

你这个不加委托都可以运行，但是放在线程中呢
如下修改
        protected void Button1_Click1(object sender, EventArgs e)
        {
            //Sockelisten();
            Thread td = new Thread(new ThreadStart(startThread));
        }
        void startThread()
        { 
            while(true){
                tsetD(1);
                Thread.Sleep(5000);
            }
        }
不就挂了
