Hi,
I have created a windows forms application with a text box for user to enter the port number onto which he wants to create a website. once the user enter the port number(as he wishes) and clicks on a button validation should be made to check in iis whether the port number is already used or not. If its already in use a messagebox should pop up showing an error message that port is already used by another site. I got some sample code from a forum but its not helping me out. Here is the code i have used but i am not able to do the validation.

try
 {
       string port = textBox2.Text;
       if (!Directory.Exists(port))
       {

         ServerManager serverManager = new ServerManager();
         Site site = serverManager.Sites.FirstOrDefault(s => s.Name == "Racing");
         SiteCollection coll = serverManager.Sites;

         foreach (Site indsite in coll)
         {
             Microsoft.Web.Administration.Binding binding = site.Bindings.Where(b => b.Protocol == "http").FirstOrDefault();
             MessageBox.Show(binding.BindingInformation.ToString());
         }
             MessageBox.Show("port number is valid");
       }
     else
     {
         MessageBox.Show("invalid");
     }
 }
 catch (Exception port)
 {
     MessageBox.Show(port.Message);
 }

Pls help me out as son as possible. Many Thanks in advance

sock.Connect(ipa, portno);
if (sock.Connected == true) // Port is in use and connection is successful
MessageBox.Show("Port is Closed");
sock.Close();

}
catch (System.Net.Sockets.SocketException ex)
{
if (ex.ErrorCode == 10061) // Port is unused and could not establish connection
MessageBox.Show("Port is Open!");
