Get Connection Status

How do you check connection status using .Net Framework 4.5?

Here's what I have:

Imports System.Net

Public Class FTPPlus2
   Shared Property HostName As String
   Shared Property Password As String
   Shared Property UserID As String
   Shared Property Target As String
   Shared Property ID As String
   Shared Property SiteName As String

   Shared Property request As FtpWebRequest
   Shared Property response As FtpWebResponse

   Shared Sub Disconnect()
      If response IsNot Nothing Then
         response.Close()
      End If
   End Sub

   Shared Sub Connect()
      request = DirectCast(WebRequest.Create(String.Format("ftp://{0}", HostName)), FtpWebRequest)
   End Sub

   Shared Sub ChangeCurrentFolder(FolderName)

   End Sub

   Shared Function Connected As Boolean
      Dim ret As Boolean  = False

      Return ret
   End Function

   Shared Sub Login()
      request.Credentials = New NetworkCredential(UserID, Password)
   End Sub
End Class

Are you trying to determine if you can connect to the internet?
If so, you can do something like this.  I've used this in various apps and it works well.
You can use any url you want, but I just use google.

using the System.Net.WebClient

public static bool CheckForInternetConnection()
{
    try
    {
        using (var client = new WebClient())
        using (var stream = client.OpenRead("http://www.google.com"))
        {
            return true;
        }
    }
    catch
    {
        return false;
    }
}

Sorry, here is vb.net version :).

Public Shared Function CheckForInternetConnection() As Boolean
      Try
            Using client = New WebClient()
                  Using stream = client.OpenRead("http://www.google.com")
                        Return True
                  End Using
            End Using
      Catch
            Return False
      End Try
End Function

I'm trying to determine the status of the FtpWebRequest.  Is there a way to determine if the connection is open/successful?

Catch the WebExceptions that GetRequestStream and GetResponse could throw.
