void ReceivedByServer()

{

   Socket socketReceive = new Socket(AddressFamily.InterNetwork, SocketType.Stream,    ProtocolType.Tcp);

   int portReceive = 90;

   IPEndPoint iPEndPointReceive = new IPEndPoint(IPAddress.Parse("0.0.0.0"),    portReceive);

   socketReceive.Bind(iPEndPointReceive);

   socketReceive.Listen(10);

   ServicePointManager.SecurityProtocol=SecurityProtocolType.Tls12;

   while (true)

   {

      Socket temp = null;

      try

      {

         temp = socketReceive.Accept();

         byte[] messageReceivedByServer = new byte[1000];

         int sizeOfReceivedMessage = temp.Receive(messageReceivedByServer, 0,          messageReceivedByServer.Length, SocketFlags.None);

         string str = Encoding.UTF8.GetString(messageReceivedByServer);

         labelShow.Text += "\r\nClient: " + str;
