How to monitor the network bandwidth usage of a specific application?

I am trying to learn how to monitor the network bandwidth usage of a specific application. I am looking at IPv4InterfaceStatistics, but that seems to monitor an NIC card's performance.
I'd like to monitor a specific application to see how much bandwidth is consumed every second.
Does anyone know of an example of how this can be done?

Here is a modified version using PerformanceCounter:

var processFileName = Path.GetFileName(Process.GetCurrentProcess().MainModule.FileName);
var bytesReceivedPerformanceCounter = new PerformanceCounter();
bytesReceivedPerformanceCounter.CategoryName = ".NET CLR Networking 4.0.0.0";
bytesReceivedPerformanceCounter.CounterName = "Bytes Received";
bytesReceivedPerformanceCounter.InstanceName = VersioningHelper.MakeVersionSafeName(processFileName, ResourceScope.Machine, ResourceScope.AppDomain);
bytesReceivedPerformanceCounter.ReadOnly = true;

Console.WriteLine("Bytes received: {0}", bytesReceivedPerformanceCounter.RawValue);

If you are familiar with the OSI model http://en.wikipedia.org/wiki/OSI_model you see that you try to interact with layer 3 where you should be interacting with layer 7.

I your connection with what ever class you are using you are able to measure bytes sent, specially if you are transporting the individual bytes, (this is since i have no idea how your code is looking), you should be able to calculate the amount of bytes over a time divide with number of seconds and you will have your result.
