Ping a host and calculate packet loss.

Ping.cs

		void GetNetworkStats(string host, int pingAmount, int timeout, out int averagePing, out int packetLoss)
		{
			Ping pingSender = new Ping();
			PingOptions options = new PingOptions(); // default is: don't fragment and 128 Time-to-Live
			
			string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
			byte[] buffer = Encoding.ASCII.GetBytes(data); // 32 bytes of data

			var failedPings = 0;
			var latencySum = 0;

			for (int i = 0; i < pingAmount; i++)
			{
				PingReply reply = pingSender.Send(host, timeout, buffer, options);
				
				if (reply != null)
				{
					if (reply.Status != IPStatus.Success)
						failedPings += 1;
					else
						latencySum += (int)reply.RoundtripTime;
				}
			}
			
			averagePing = (latencySum / pingAmount);
			packetLoss = (failedPings / pingAmount) * 100;
		}

averagePing = (latencySum / (pingAmount - failedPings));
packetLoss = Convert.ToInt32((Convert.ToDouble(failedPings) / Convert.ToDouble(pingAmount)) * 100);
