title: Netstat -ban (or -oan) equivalent in .NET
body: <p>I'd like to know if a particular process is using a given port, i.e. <code>netstat -ban</code>. I came across using <code>IPGlobalProperties</code> to get the list of active connections, but this doesn't seem to include process information. </p>
  
  <p>It would be nice if there exists some class in C# that lets me do this programmatically. Ideally, I wouldn't have to pipe the cmd shell <code>Process</code> output.</p>
