How can I get all the the active TCP connections using .NET Framework (no unmanaged PE import!)?

I'm getting into socket programming and would like to check this. In my research I found solutions by importing an unmanaged DLL file which I am not interested in.

I'm surprised with the quantity of users telling me that was not possible to do with pure managed code... For future users who is wondering about that, find the details from the answer that worked fine for me:

//Don't forget this:
using System.Net.NetworkInformation;

public static void ShowActiveTcpConnections()
{
    Console.WriteLine("Active TCP Connections");
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    TcpConnectionInformation[] connections = properties.GetActiveTcpConnections();
    foreach (TcpConnectionInformation c in connections)
    {
        Console.WriteLine("{0} <==> {1}",
                          c.LocalEndPoint.ToString(),
                          c.RemoteEndPoint.ToString());
    }
}

And call ShowActiveTcpConnections() to list it, awesome and beautiful.
