i need keep pipestrem open , not close it, i.e. rid off using. tried keep open, exception cannot access closed strem how can solve it? code now:

    public static void startserver()     {          //namedpipeserverstream pipestream = new namedpipeserverstream("pipeto" + process.getcurrentprocess().id.tostring());          while(true)         {             using (namedpipeserverstream pipestream = new namedpipeserverstream("pipeto" + process.getcurrentprocess().id.tostring()))             {                  console.writeline("[server] pipe created, current process id {0};\n[server] current process name {1}", process.getcurrentprocess().id.tostring(), process.getcurrentprocess().processname);                 try { pipestream.waitforconnection(); }                 catch                 {                     _worker = new backgroundworker();                     _worker.dowork += _worker_dowork;                 }                 console.writeline("[server] connected successfully");                  using (streamreader sr = new streamreader(pipestream))                 {                                             string pathtoexe = string.empty;                      while ((pathtoexe = sr.readline()) != null)                     {                         process.start(pathtoexe);                                                 }                 }             }         }     } 

using on either stream itself, or streamreader cause close.

for more information: does disposing streamreader close stream?
