如何从system.diagnostics.process停止进程并继续读取直到结束 [英] How to stop a process from system.diagnostics.process and continue reading till the end
问题描述
我正在使用此代码，但是当我停止该过程时，它无法获得ping统计信息：
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 + " " + adresa;
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));
}
}
}
}
}
不使用
Without using
if(dt > DateTime.Now)
{
p.StandartInput.Write("\x3");
}
结果显示如下：
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>
但如果我使用
but if I stop the ping using
p.StandartInput.Write("\x3"); 停止ping，它永远不会进入统计部分它挂起在序列1并且不继续读取，如何在停止ping过程后显示统计信息？
换句话说我的问题是当用户想要停止ping它应该显示用于ping的特定时间的统计数据...
我尝试过：
尝试：
it never goes to the statistics part it hangs at sequence 1 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...
What I have tried:
Trying with :
p.StandartInput.WriteLine("\x3");
和：
and with :
scanner.Reset;
但问题仍然存在......
But still the same problem ...
