I'd like to know if there is any way to access info like number of discarded packets from within .NET framework. I am aware of Win32_PerRawData and Ip Helper API. Thanks in advance

Your can use the PerformanceCounter class. Run Perfmon.exe to find out what's available on your machine. You should have Network Interface + Packets Received Discarded for each of your network adapters for example.

Do you know some nice reading/tutorial on this? I'm new to windows programming and msdn seems too spaghetti for me. Anyway, thanks, I think it's what I was looking for.
This is lazy and cheating here but....I know I will get flamed for this...Would you not consider using a process to execute netstat -e n where n is the interval in number of seconds. If you are talking about a Winforms/WPF, using the System.Diagnostics.Process class to shell out to a hidden window with the output redirected to an input stream in which you can parse the discarded packets?
Edit: Here's a suggested code sample
public class TestNetStat
{
private StringBuilder sbRedirectedOutput = new StringBuilder();
public string OutputData
{
get { return this.sbRedirectedOutput.ToString(); }
}
public void Run()
{
System.Diagnostics.ProcessStartInfo ps = new System.Diagnostics.ProcessStartInfo();
ps.FileName = "netstat";
ps.ErrorDialog = false;
ps.Arguments = "-e 30"; // Every 30 seconds
ps.CreateNoWindow = true;
ps.UseShellExecute = false;
ps.RedirectStandardOutput = true;
ps.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
using (System.Diagnostics.Process proc = new System.Diagnostics.Process())
{
proc.StartInfo = ps;
proc.Exited += new EventHandler(proc_Exited);
proc.OutputDataReceived += new System.Diagnostics.DataReceivedEventHandler(proc_OutputDataReceived);
proc.Start();
proc.WaitForExit();
proc.BeginOutputReadLine();
while (!proc.HasExited) ;
}
}
void proc_Exited(object sender, EventArgs e)
{
System.Diagnostics.Debug.WriteLine("proc_Exited: Process Ended");
}
void proc_OutputDataReceived(object sender, System.Diagnostics.DataReceivedEventArgs e)
{
if (e.Data != null) this.sbRedirectedOutput.Append(e.Data + Environment.NewLine);
// Start parsing the sbRedirected for Discarded packets...
}
}
Simple, hidden window....
Hope this helps, Best regards, Tom.
