Check if port 57875 is closed on localhost VB.Net?

I am trying to see if port 57875 on localhost, the computer, is closed. Here is the code I have so far:

Try
        Dim checkPort As TcpClient = New TcpClient("localhost", 57875)
    Catch ex As Exception
        MsgBox("WARNING: Port 57875 is not forwarded ! The game will probably encounter an error !")
    End Try

Even if it is forwarded, it will think it isn't. What is wrong with the code?

Here you have an example:

Dim host As String = "localhost"

Dim port As Integer = 57875

Dim addr As IPAddress = DirectCast(Dns.GetHostAddresses(host)(0), IPAddress)

Try   

    Dim tcpList As New TcpListener(addr, port)   
    tcpList.Start()

Catch sx As SocketException
  'Catch exception - No available port
End Try
