public void LoadAveragePingTime()
{
    try
    {
        PingReply pingReply = pingClass.Send("logon.chronic-domination.com");
        double AveragePing = (pingReply.RoundtripTime / 1.75);

        label4.Text = (AveragePing.ToString() + "ms");                
    }
    catch (Exception)
    {
        label4.Text = "Server is currently offline.";
    }
}

目前我的label4.Text得到类似的东西:"187.371698712637".

我需要它来表示:"187.34"

DOT后只有两个帖子.有人可以帮我吗？
