private void button3_Click(object sender, EventArgs e)

ping.PingCompleted += new PingCompletedEventHandler(_myPing_PingCompleted); for(int i = 0; i < dataGridView1.Rows.Count; i++)
{
if (Convert.ToString(dataGridView1.Rows[i].Cells[1].Value) != "")
{
string _ipAddress = Convert.ToString(dataGridView1.Rows[i].Cells[1].Value);
//每一行的datagridview中的第二格都有IP地址
PingReply result = ping.Send(_ipAddress); if (result.Status != IPStatus.Success)
{
dataGridView1.Rows[i].Cells[3].Value = result.RoundtripTime.ToString();
}
}
}
}
求指导,我现在这个是多线程ping了吧,为啥我这个ping多个地址很慢的,,,别人做出的程序ping多个地址很快。。而我的没效率啊。。求改进

这部分是放在异步回调里面处理的
