如果socket连接服务器失败，会继续尝试连接。但是界面会卡住，该如何解决

        public delegate void connDelegate();

        private void conn()

        {

            try

            {

                socket.Connect(ipe); //连接到服务器

                listBox1.Items.Add("socket连接成功，准备接收数据...");

                listBox1.Refresh();

                showLB1.Text = "socket连接成功，准备接收数据...";

                showLB1.Refresh();

            }

            catch (Exception ee)

            {

                Console.WriteLine("Exception:{0}", ee);

                listBox1.Items.Add("连接失败，正在重试，请稍后!");

                listBox1.Refresh();

                showLB1.Text = "连接失败，正在重试，请稍后! ";

                showLB1.Refresh();

            }

        }



       private void okBtn_Click(object sender, EventArgs e)

        {

            connDelegate connDele = new connDelegate(conn);

            this.ip = ipTB.Text;

            portS = portTB.Text;

            this.path = textBox1.Text;

            if (this.ip == "" || portS == "" || this.path == "")

            {

                showLB1.Text = "ip,port和文件的输入框不能为空!";

            }

            MessageBox.Show(ip);



            this.port = int.Parse(portS);

            try

            {

                //创建终结点EndPoint

                ipaddress = IPAddress.Parse(this.ip);

                ipe = new IPEndPoint(ipaddress, this.port);



                //创建Socket并连接到服务器

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

            }

            catch (Exception ex)

            {

                Console.WriteLine(ex);

            }

            while (!socket.Connected)

            {

                Thread.Sleep(2000);

                Invoke(connDele);

            }



        }
