Asp.Netで実現したping機能は、仮想ホストで実行可能

public 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 ， ：      System.Net.NetworkInformation.PingReply reply =      p.Send(ip, timeout, buffer, options);      if (reply.Status ==      System.Net.NetworkInformation.IPStatus.Success)          return true ;      else          return false ; }
