Maybe try some other search terms

A quick look at NET VIGILANT: Network Monitor and I think that it's something that you must read to get a little understanding what you're getting into. read the introduction and tools and techniques.

There are other links in the google results that might give you straight away what you need without going into the low level stuff.

Good luck.

class Program
{


static void Main(string[] args)
{




foreach(Process pss in Process.GetProcesses())
{

NetworkTraffic trafficMonitor = new NetworkTraffic(pss.Id);
string totalBandwidthConsumption;

string lastAmountOfBytesReceived;
float currentAmountOfBytesReceived = trafficMonitor.GetBytesReceived();
float currentAmountOfBytesSent = trafficMonitor.GetBytesSent();


totalBandwidthConsumption = string.Format("Total Bandwidth Consumption: {0} kb", (currentAmountOfBytesReceived + currentAmountOfBytesSent) / 1024);

Console.WriteLine("Process Name:+"+pss.ProcessName.ToString());
Console.WriteLine("Bytes Sent:+"+currentAmountOfBytesSent);
Console.WriteLine("Bytes Receive:+"+currentAmountOfBytesReceived);
Console.WriteLine("Total Bytes:+"+totalBandwidthConsumption);
}
}

}


public class NetworkTraffic
{
private PerformanceCounter bytesSentPerformanceCounter;
private PerformanceCounter bytesReceivedPerformanceCounter;
private int pid;
private bool countersInitialized;


public NetworkTraffic(int processID)
{
pid = processID;
TryToInitializeCounters();
}


private void TryToInitializeCounters()
{
if (!countersInitialized)
{
PerformanceCounterCategory category = new PerformanceCounterCategory(".NET CLR Networking 4.0.0.0");


var instanceNames = category.GetInstanceNames().Where(i => i.Contains(string.Format("p{0}", pid)));


if (instanceNames.Any())
{
bytesSentPerformanceCounter = new PerformanceCounter();
bytesSentPerformanceCounter.CategoryName = ".NET CLR Networking 4.0.0.0";
bytesSentPerformanceCounter.CounterName = "Bytes Sent";
bytesSentPerformanceCounter.InstanceName = instanceNames.First();
bytesSentPerformanceCounter.ReadOnly = true;


bytesReceivedPerformanceCounter = new PerformanceCounter();
bytesReceivedPerformanceCounter.CategoryName = ".NET CLR Networking 4.0.0.0";
bytesReceivedPerformanceCounter.CounterName = "Bytes Received";
bytesReceivedPerformanceCounter.InstanceName = instanceNames.First();
bytesReceivedPerformanceCounter.ReadOnly = true;


countersInitialized = true;
}
}
}


public float GetBytesSent()
{
float bytesSent = 0;


try
{
TryToInitializeCounters();
bytesSent = bytesSentPerformanceCounter.RawValue;
}
catch { }


return bytesSent;
}


public float GetBytesReceived()
{
float bytesSent = 0;


try
{
TryToInitializeCounters();
bytesSent = bytesReceivedPerformanceCounter.RawValue;
}
catch { }


return bytesSent;
}
}

i am getting process names but not sent and receive packets
i.e
Process Name:+smss
Bytes Sent:+0
Bytes Receive:+0
Total Bytes:+Total Bandwidth Consumption: 0 kb
Process Name:+explorer
Bytes Sent:+0
Bytes Receive:+0
Total Bytes:+Total Bandwidth Consumption: 0 kb
Process Name:+System
Bytes Sent:+0
Bytes Receive:+0

Does anyone have any Idea????? please guide
