我对powershell编程很陌生，我有以下脚本，只要数据可用，它就会从套接字流中读取，然后发送一个“q”退出连接。我在 win 2003 server std,Power shell V2.0 上运行它。当我执行 pgm 时，输出是来自 pgm 的文本，它正在读取和缓冲。它几乎看起来像以下是输出：

在端口 23 上连接到 aardwolf.org

while($stream.DataAvailable)  
       {  
     $read = $stream.Read($buffer, 0, 1024)  
write-Host $read  
if($read -gt 0)  
{  
      $outputBuffer += ($encoding.GetString($buffer, 0, $read))  
}  
    }## Read the user's command, quitting if they hit

以下是代码：

# Interact with a service on a remote TCP port
param( [string] $remoteHost = "aardwolf.org",
[int] $port = 23     )

## Open the socket, and connect to the computer on the specified port 

write-host "Connecting to $remoteHost on port $port"  
$socket = new-object System.Net.Sockets.TcpClient($remoteHost, $port) 
if($socket -eq $null) { return; } 

$stream = $socket.GetStream() 
$writer = new-object System.IO.StreamWriter($stream)

$buffer = new-object System.Byte[] 1024 
$encoding = new-object System.Text.AsciiEncoding
while($true)    
{    
## Allow data to buffer for a bit
start-sleep -m 500 
$outputBuffer = ""  
## Read all the data available from the stream, writing it to the       ## screen when   done.              
if($stream.CanRead)
{   
while($stream.DataAvailable)  
    {  
     $read = $stream.Read($buffer, 0, 1024) 
write-Host $read 
if($read -gt 0)
{ 
      $outputBuffer += ($encoding.GetString($buffer, 0, $read)) 
}
    }## Read the user's command, quitting if they hit 
}
write-Host $outputBUffer
   $command = "q"    
   $writer.WriteLine($command) 
   $writer.Flush()
break

} ## 关闭流 if($writer -ne $null)
{ $writer.Close()
$stream.Close() }

需要一些帮助来解决问题。
