I want to write a program in c# which will give me network bandwidth usage per protocol like 80, 8080, 443 etc. I have written code to calculate total bytes sent and received using NetworkInterface class but I am not getting any method/class to calculate the bytes per port like 80,8080,443 etc.
Please assist in this.

Thanks Ravi for your comment. I looked into this but it is giving packet capture details, I didn't get the details of bytes usage for each protocol. Could you please help me in understanding this?

I am using below code to get total bytes sent and received.

IPv4InterfaceStatistics interfaceStatistic = networkInterface.GetIPv4Statistics();
double bytesSentSpeed = (double)(interfaceStatistic.BytesSent – lngBytesSend) / 1024;
double bytesReceivedSpeed = (double)(interfaceStatistic.BytesReceived – lngBtyesReceived) / 1024;

Is there any way like this to get the bytes sent and received for specific protocol/port?
