c# - Sockets: Only one usage of each socket address is normally permitted -

i want reuse socket after used once, subj exception. found multiple questions same issue no working solution. tried using code, tried manual closing - without success

a little sample

using system; using system.net; using system.net.sockets; using system.text;  namespace sockettest {     class program     {         static void main()         {             (int = 1; <= 2; i++)             {                 var encoding = new utf8encoding(false);                 var host = dns.gethostentry("localhost");                 var endpoint = new ipendpoint(host.addresslist[0], 11322);                 console.writeline("iteration #{0}\tenpdoint = {1}", i, endpoint);                 try                 {                      var client = new tcpclient(endpoint);                      const string message = "hello world!";                     byte[] data = encoding.getbytes(message);                     client.connect(endpoint);                     var stream = client.getstream();                      stream.write(data, 0, data.length);                     console.writeline("sent: {0}", message);                       byte[] receivedata = new byte[4096];                     int totalbytes = 0;                     while (true)                     {                         int bytesread = stream.read(receivedata, 0, receivedata.length);                         totalbytes += bytesread;                         if (bytesread < receivedata.length)                             break;                         array.resize(ref receivedata, 2 * receivedata.length);                     }                      var response = encoding.getstring(receivedata, 0, totalbytes);                     console.writeline("received: {0}", response);                      client.client.shutdown(socketshutdown.both);                     client.client.disconnect(true);                     stream.close();                     client.close();                 }                 catch (exception ex)                 {                     console.writeline(ex.tostring());                 }                 console.writeline();             }         }     } }
