废话不多说，直接上代码：

using System;
using System.Collections.Generic;
using System.Text;
 
namespace isConnInternet
{
    public class IsConnInt
    {
        public bool isConn()
        {
            System.Net.NetworkInformation.Ping ping;
            System.Net.NetworkInformation.PingReply res;
            ping = new System.Net.NetworkInformation.Ping();
            try
            {
                res = ping.Send("www.lcyuandaima.com");
                if (res.Status != System.Net.NetworkInformation.IPStatus.Success)
                    return false;
                else
                    return true;
            }
            catch (Exception er)
            {
                return false;
            }
        }
    }
}
