c#ping功能实现，相当简单

不多说，直接上码。

 public static  bool Ping(string ip)

        {

            System.Net.NetworkInformation.Ping p = new System.Net.NetworkInformation.Ping();

            System.Net.NetworkInformation.PingOptions options = new System.Net.NetworkInformation.PingOptions();

            options.DontFragment = true;

            string data = "Test Data!";

            byte[] buffer = Encoding.ASCII.GetBytes(data);

            int timeout = 1000; // Timeout 时间，单位：毫秒

            System.Net.NetworkInformation.PingReply reply = p.Send(ip, timeout, buffer, options);

            if (reply.Status == System.Net.NetworkInformation.IPStatus.Success)

                return true;

            else

                return false;

        }

使用方法：

 bool kk=network.Ping("192.168.30.47"); 是八是相当简单啊，模块式潮汐的
