Thread eating too much cpu while streamReading

*edit* so this wasn't causing my game to be sluggish, something else was. But still, I would like to know if there is a better way of using this thread to be efficient.


My thread is supposed to read information sent by a server, and the information could come at any point in time. Right now I believe this thread is eating up too much cpu usage and is causing my game to be sluggish. Does anyone know how I can reduce the resources needed for this thread?
I understand that the while loop is basically going off without downtime, so it's throwing cpu out the window :( After googling a whole bunch of stuff that I'm not completely sure how to use properly, I'm stuck.

static public void Listener()   //thread
        {
            networkStream = socketForServer.GetStream(); 
            streamReader =
            new StreamReader(networkStream);
            while (true)
            {

                try
                {
                    
                    string outputString;
                    outputString = streamReader.ReadLine(); // recieves info
                    RecievedMessage = outputString;
                    if (outputString != null) { board.GetMessageFromClient(); } 
                                               //if info isn't null send it out
                }
                catch {  }
            }
        }
