How to stop a process from System.Diagnostics.Process and get the statistics in the end

Question

I'm using this code but when i stop the process it not get the ping statistics :

System.Diagnostics.Process p = new System.Diagnostics.Process(); p.StartInfo.FileName = "ping"; p.StartInfo.Arguments = "-c " + count + " -i " + interval + " -s " + buffer + " -W " + timeout + " " + address; p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = true;  string readData = "";  DateTime dt = DateTime.Now.AddSeconds(5); if (p.Start()) {     Scanner scanner = new Scanner(p.StandardOutput.BaseStream);      while (scanner.HasNextLine)     {         readData =  scanner.NextLine().ToString();         Console.WriteLine(readData.ToString());          if (!string.IsNullOrEmpty(readData) && !readData.StartsWith("---"))         {             Match M = Regex.Match(readData, @"^[\d]+ bytes from ([^:]+): [^ ]+ ttl=([\d]+) time=([^ ]+) ms");              if (M != null && M.Success)             {                 string IP = M.Groups[1].Value;                 string TTL = M.Groups[2].Value;                 string timeStr = M.Groups[3].Value;                  Console.WriteLine(String.Format("Ping to {0} took {2} ms with a ttl of {1}", IP, TTL, timeStr));                 // Parsing the timeStr will work the same way as above                if(dt > DateTime.Now)                {                    p.StandartInput.Write("\x3");                 }             }             else             {                 Match M1 = Regex.Match(readData, @"^rtt [^0-9]*([\d][^\/]+)\/([^\/]+)\/([^\/]+)\/([^ ]+) ms$");                  if (M1 != null && M1.Success)                 {                     float avgPingTime = 0;                     float maxPingTime = 0;                     float minPingTime = 0;                      string minPingString = M1.Groups[1].Value;                     string avgPingString = M1.Groups[2].Value;                     string maxPingString = M1.Groups[3].Value;                      // Now parse that value                     float.TryParse(minPingString, System.Globalization.NumberStyles.Float, System.Globalization.NumberFormatInfo.InvariantInfo, out minPingTime);                     float.TryParse(avgPingString, System.Globalization.NumberStyles.Float, System.Globalization.NumberFormatInfo.InvariantInfo, out avgPingTime);                     float.TryParse(maxPingString, System.Globalization.NumberStyles.Float, System.Globalization.NumberFormatInfo.InvariantInfo, out maxPingTime);                      Console.WriteLine(String.Format("Min Time : {0} , AVG {2} ms, Max Time {1}", minPingTime, maxPingTime, avgPingTime));                 }             }         }     } } 

Without using

if(dt > DateTime.Now) {      p.StandartInput.Write("\x3"); } 

the result display like this :

64 bytes from 8.8.8.8: icmp_req=1 ttl=46 time=13.9 ms 64 bytes from 8.8.8.8: icmp_req=2 ttl=46 time=13.9 ms 64 bytes from 8.8.8.8: icmp_req=3 ttl=46 time=13.9 ms  --- 8.8.8.8 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 3016ms rtt min/avg/max/mdev = 13.910/13.926/13.951/0.010 ms 

but if I stop the ping using p.StandartInput.Write("\x3"); it never goes to the statistics part it hangs at sequence 1 : 64 bytes from 8.8.8.8: icmp_req=1 ttl=46 time=13.9 ms and dont continue reading , how to show the statistics after stoping the ping process ?

in other words my problem is when the user want to stop the ping it should display the statistics for the certain time that it was used to ping...

UPDATE

I have implemented p.StandartInput.Write("/x3"); and it interrupts the ping process but it does not display the statistics and just hangs there.

If you are actually interested in the ping values, why not just use the ping class? https://msdn.microsoft.com/en-us/library/system.net.networkinformation.ping(v=vs.110).aspx
