UDPClient in C# -

i use in udpclient in c#. invoke receive function, when running app. program enter eternity loop. why phenomenon? maybe because no data available on port? can do?

i write following code:

       udpclient udpclient = new udpclient(623);         try         {             udpclient.connect("10.0.0.16", 623);              // sends message host have connected.             byte[] sendbytes = encoding.ascii.getbytes("is there?");              udpclient.send(sendbytes, sendbytes.length);              // sends message different host using optional hostname , port parameters.             udpclient udpclientb = new udpclient();             udpclientb.send(sendbytes, sendbytes.length, "10.0.0.16", 623);              //ipendpoint object allow read datagrams sent source.             ipendpoint remoteipendpoint = new ipendpoint(ipaddress.any, 0);              // blocks until message returns on socket remote host.             byte[] receivebytes = udpclient.receive(ref remoteipendpoint);             string returndata = encoding.ascii.getstring(receivebytes);              // uses ipendpoint object determine of these 2 hosts responded.             console.writeline("this message received " +                                          returndata.tostring());             console.writeline("this message sent " +                                         remoteipendpoint.address.tostring() +                                         " on port number " +                                         remoteipendpoint.port.tostring());              udpclient.close();             udpclientb.close();          }         catch (exception e)         {             console.writeline(e.tostring());         } 

thanks

i suspect it's because of no data, test this, try implementing 'beginrecieve' instead of recieve. msdn has example:
