The Winpcap library is an excellent method of reading and writing data packet, but it is not so easy to interface to from .NET. Thus this design tip uses a code wrapper from the Code Project [Click here]. The solution and demo of this example is at:

and uses the following code:
using System;
using Tamir.IPLib;
namespace NapierCapture
{
public class ShowDevices
{
public static void Main(string[] args)
{
string verWinPCap =null;
int count=0;
verWinPCap= Tamir.IPLib.Version.GetVersionString();
PcapDeviceList getNetConnections = SharpPcap.GetAllDevices();
Console.WriteLine("WinPCap Version: {0}", verWinPCap);
Console.WriteLine("Connected devices:\r\n");
foreach(PcapDevice net in getNetConnections)
{
Console.WriteLine("{0}) {1}",count,net.PcapDescription);
Console.WriteLine("\tName:\t{0}",net.PcapName);
Console.WriteLine("\tMode:\t\t\t{0}",net.PcapMode);
Console.WriteLine("\tIP Address: \t\t{0}",net.PcapIpAddress);
Console.WriteLine("\tLoopback: \t\t{0}",net.PcapLoopback);
Console.WriteLine();
count++;
}
Console.Write("Press any <RETURN> to exit");
Console.Read();
}
}
}
A sample run shows the details of the network connections:
WinPCap Version: 1.0.2.0
Connected devices:
0) Realtek RTL8169/8110 Family Gigabit Ethernet NIC
(Microsoft's Packet Scheduler)
Name: \Device\NPF_{A22E93C1-A78D-4AFE-AD2B-517889CE42D7}
Mode: Capture
IP Address: 192.168.2.1
Loopback: False 1) Intel(R) PRO/Wireless 2200BG Network Connection (Microsoft's Packet Scheduler)

Mode: Capture
IP Address: 192.168.1.101
Loopback: False |
A simple enhancement gives more adaptor details:
using System;
using Tamir.IPLib;
namespace NapierCapture
{
public class ShowDevices
{
public static void Main(string[] args)
{
string verWinPCap =null;
int count=0;
verWinPCap= Tamir.IPLib.Version.GetVersionString();
PcapDeviceList getNetConnections = SharpPcap.GetAllDevices();
Console.WriteLine("WinPCap Version: {0}", verWinPCap);
Console.WriteLine("Connected devices:\r\n");
foreach (PcapDevice net in getNetConnections)
{
Console.WriteLine("{0}) {1}",count,net.PcapDescription);
NetworkDevice netConn = (NetworkDevice)net;
Console.WriteLine("\tIP Address:\t\t{0}",netConn.IpAddress);
Console.WriteLine("\tSubnet Mask:\t\t{0}",netConn.SubnetMask);
Console.WriteLine("\tMAC Address:\t\t{0}",netConn.MacAddress);
Console.WriteLine("\tDefault Gateway:\t{0}",netConn.DefaultGateway);
Console.WriteLine("\tPrimary WINS:\t\t{0}",netConn.WinsServerPrimary);
Console.WriteLine("\tSecondary WINS:\t\t{0}",netConn.WinsServerSecondary);
Console.WriteLine("\tDHCP Enabled:\t\t{0}",netConn.DhcpEnabled);
Console.WriteLine("\tDHCP Server:\t\t{0}",netConn.DhcpServer);
Console.WriteLine("\tDHCP Lease Obtained:\t{0}",netConn.DhcpLeaseObtained);
Console.WriteLine("\tDHCP Lease Expires:\t{0}",netConn.DhcpLeaseExpires);
Console.WriteLine();
count++;
}
Console.Write("Press any <RETURN> to exit");
Console.Read();
}
}
}
This gives:
