Vista - problem with very simple tcpclient in powershell

Hi there,

I created a server in C# using TcpListner which is working fine. To connect
to that server, i created a powershell script as follows:

$s = new-object System.Net.Sockets.TcpClient("127.0.0.1", 4099)
$str = $s.GetStream
$wrtr = new-object System.IO.StreamWriter($str)
$wrtr.WriteLine("Hello world!");
$wrtr.Flush
$wrtr.Close();
$s.Close()

Now, this is a very simple script and the SAME EQUIVALENT when written in C#
works fine.

But when i run this from the powershell, i get no errors, the Server
definitely detects the connection, but it NEVER receives anything sent from
WriteLine(). The same code written in C# works fine... even WriteLine()
works fine in C# but not powershell.

I do not get any error message either. What might be going wrong?

Any help is appreciated.

Thank you

Not sure why you aren't getting an error but you need parenthases after
GetStream otherwise the return value will be MethodInfo's.

thing, you don't have your Flush method specified properly, it should be:
$wrtr.Flush()

(Semi-colons aren't required in PowerShell unless you put things on the
same line.)

$s = new-object System.Net.Sockets.TcpClient("127.0.0.1", 8001)
$str = $s.GetStream()
$wrtr = new-object System.IO.StreamWriter($str)
$wrtr.Write("Test");
$wrtr.Flush();
$wrtr.Close();
$s.Close()

You had *2* spots where you were missing the "()" on a method.

equally well now.
