如何在 C# 中实现控制台命令 ping - a 10.10.10.1

Question

我能够使用 C# 实现 ping（以检查机器是否可用）。

但我无法获得控制台命令 ping [-a] targetipaddress 的等价物，它也将地址解析为主机名。

我需要在非域场景（例如工作组）的情况下使用。

示例：(a) 从命令控制台 ping 10.10.10.1 使用 ping (b) ping -a 10.10.10.1

我用于 (a) 的代码

    static string pingmachine(string ipaddress)
    {

        Ping ping = new Ping();
        PingReply pingresult = ping.Send(ipaddress);
        return pingresult.Status.ToString();

    }

请帮我完成与示例 (b) 等效的操作。谢谢。

非常简单。

            // 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);
