Question

How do I calculate amount downloaded by a computer?

Answer 1

+1 A:

I'd use some built for purpose solution. Google 'cybercafe management software' - there are tons of results:

e.g.: www.handycafe.com/

Yup, the question as phrased is proggramming-related, but _it shouldn't have been_.

Of course, he might be trying to create a cybercafe management system for profit, in which case my answer isn't very helpful! (appart from perhaps highligting the fact that it's a crowded market) But if he's trying to run a cybercafe (and create his own solution for it) then that's how I'd go.

There are many clues in my question suggesting I'm 'creating' a Cybercafe management system.

Answer 2

+2 A:

I just found System.Net.NetworkInformation namespace and wrote following code:

NetworkInterface[] networkInterfaces = 
    NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface ni in networkInterfaces)
{
    IPv4InterfaceStatistics stats = ni.GetIPv4Statistics();
    IPInterfaceProperties props = ni.GetIPProperties();
    Console.WriteLine("{0} ({1:#,##0.00}Mb/s, {2})",
        ni.Name, ni.Speed / 1024D / 1024D, ni.OperationalStatus);
    Console.WriteLine("\t{0}", ni.Description);

    Console.WriteLine("\t{0:#,##0.00}Mb sent, {1:#,##0.00}Mb received",
        stats.BytesSent / 1024D / 1024D, stats.BytesReceived / 1024D / 1024D);
    Console.WriteLine();
}

I got this output:

Local Area Connection 2 (953,67Mb/s, Up)
        Realtek RTL8169/8110 Family PCI Gigabit Ethernet NIC (NDIS 6.0)
        1.906,92Mb sent, 483,77Mb received

Local Area Connection 3 (9,54Mb/s, Down)
        D-Link DFE-520TX PCI Fast Ethernet Adapter
        0,00Mb sent, 0,00Mb received

Loopback Pseudo-Interface 1 (1.024,00Mb/s, Up)
        Software Loopback Interface 1
        0,00Mb sent, 0,00Mb received

This is very good; however, is there a way I can differentiate data sent and received from the Internet and local network traffic?

+1 A:

You can also read the performance counters on the system. See PerformanceCounter class in .NET. For a list of available performance counters on your machine. Start->Run Perfmon -> Do "Add Counters" to see the ones available.
