我打算开发一个网站，每隔一段时间就 ping 域以检查域状态。参考站点：http://pingdom.com/ 这个站点也喜欢这样做。如何使用 C# 获取 Ping 统计信息？

【解决方案1】：

使用Ping class

        Ping pingSender = new Ping ();
        PingOptions options = new PingOptions ();

        // Use the default Ttl value which is 128,
        // but change the fragmentation behavior.
        options.DontFragment = true;

        // Create a buffer of 32 bytes of data to be transmitted.
        string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
        byte[] buffer = Encoding.ASCII.GetBytes (data);
        int timeout = 120;
        PingReply reply = pingSender.Send (args[0], timeout, buffer, options);
        if (reply.Status == IPStatus.Success)
        {
            Console.WriteLine ("Address: {0}", reply.Address.ToString ());
            Console.WriteLine ("RoundTrip time: {0}", reply.RoundtripTime);
            Console.WriteLine ("Time to live: {0}", reply.Options.Ttl);
            Console.WriteLine ("Don't fragment: {0}", reply.Options.DontFragment);
            Console.WriteLine ("Buffer size: {0}", reply.Buffer.Length);
        }

您可以在 Global.asax 中启动计时器，并使用 Ping 类在每个时间间隔内 ping 您的域

【讨论】：

它不是 Global.aspx 而是 Global.asax
糟糕，已修复 @Shekhar_Pro，谢谢
谢谢@Shekhar_Pro，你也+1 ;)
你是在做工作还是做个人生意？

您可以使用PING 类。您可以使用发送方法进行 ping 操作并接收回显。

        Ping pingSender = new Ping ();
        PingOptions options = new PingOptions ();

        // Use the default Ttl value which is 128,
        // but change the fragmentation behavior.
        options.DontFragment = true;

        // Create a buffer of 32 bytes of data to be transmitted.
        string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
        byte[] buffer = Encoding.ASCII.GetBytes (data);
        int timeout = 120;
        PingReply reply = pingSender.Send (args[0], timeout, buffer, options);
        if (reply.Status == IPStatus.Success)
        {
            Console.WriteLine ("Address: {0}", reply.Address.ToString ());
            Console.WriteLine ("RoundTrip time: {0}", reply.RoundtripTime);
            Console.WriteLine ("Time to live: {0}", reply.Options.Ttl);
            Console.WriteLine ("Don't fragment: {0}", reply.Options.DontFragment);
            Console.WriteLine ("Buffer size: {0}", reply.Buffer.Length);
        }
