Re-opening a closed NetworkStream?

Question

Good morning,

I am in need of some advice, I am using a networkStream, which is streaming from a TcpClient, all was working fine, but then I required the some functionality elsewhere, which requires the stream to be closed. I can't seem to find a way to re open the connection once it has been closed. Could anyone point me in the correct direction here?

Here's an example of the code I am based on: (Obviously this isn't exactly how it works, but I've simplified it as much as possible :-))

private void MyMainFunction()
  {
  ConnectToTcp();

  if(CheckConnection == true)
    {
    DoWorkWithTcp();
    }

  DisconnectFromTcp();

  ConnectViaOtherSource();
  DoOtherSourceWork();
  DisconnectOtherSource();

  ConnectToTcp(); //Excecption thrown, epic fail!
  }

private void ConnectToTcp()
  {
  myClient = new TcpClient(ip, port);
  myNetStream = myClient.GetStream();
  }

private void DisconnectFromTcp()
  {
  myNetStream.Close();
  myClient.Close();
  }

Thanks in advance, appreciated.

Edit - Changed variable spelling name! Whoops!

Edit - Sorry, just realised the problem was coming from elsewhere, thanks for confirming that this code is correct :-) Helped me spot the problem from another source

Answer 1

Not sure since you didnt paste the whole thing but

myClient = new TcpClient(ip, port); myNetStream = sockClient.GetStream();

sockClient is not myClient is this a typo or its actually in the code? if thats the case you need to recreate sockClient aswell

The question comes up why you have to close the connection at all, can't you keep it open (dormant) during DoOtherSourceWork() ?

Apart from that, the code looks OK, creating a new TcpClient etc, so I think it depends on the other side - what does the peer software do when you close the connection?
