Chilkat套接字不发送字符串

我正在使用Chilkat库构建套接字数据重定向,可以将客户端连接到套接字服务器,但是,当我执行将数据重定向到连接的客户端的程序时,出现了错误来自chilkat lib。说没有连接(到客户端)。

我的服务器测试代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

namespace CallSocketTest
{
    public class TestSocket
    {
        public Dictionary<string, ConnectionManager> Connections { get; set; } = new Dictionary<string, ConnectionManager>();

        public TestSocket(){}

        public void StartConnectionHandler()
        {
            Thread th = new Thread(() =>
            {
                FooSocket listeningSocket = new FooSocket();
                listeningSocket.BindAndListen(5000, 300);

                while (true)
                {
                    FooSocket connectedSocket = listeningSocket.AcceptNextConnection(0);
                    var connection = new ConnectionManager(this, connectedSocket);

                    string connectionKey = "";
                    do
                    {
                        connectionKey = Guid.NewGuid().ToString();
                        if (!Connections.ContainsKey(connectionKey))
                            break;
                    } while (true);

                    Connections[connectionKey] = connection;
                    Connections[connectionKey].StartReadFromClient();

                    Console.WriteLine("CONN: {0}", connectionKey);
                }
            });
            th.Start();
        }
    }

    public class ConnectionManager
    {
        private FooSocket Socket { get; set; }
        private TestSocket SocketTest { get; set; }

        public ConnectionManager(TestSocket testSocket, FooSocket fooSocket)
        {
            Socket = fooSocket;
            SocketTest = testSocket;
        }

        public void StartReadFromClient()
        {
            Thread th = new Thread(() => ReadMessageFromClient());
            th.Start();
        }

        private void ReadMessageFromClient()
        {
            do
            {
                if (!Socket.IsConnected)
                    break;

                var dataRead = Socket.ReadString();
                if (dataRead.Trim().Length == 0)
                    continue;

                // <guid>|<Message>
                var dataSplt = dataRead.Split('|');

                SocketTest.Connections[dataSplt[0]].Socket.SendString(dataSplt[1]);
            } while (true);

            Socket.CloseConnection();
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            TestSocket cnn = new TestSocket();
            cnn.StartConnectionHandler();

            while (true)
                Thread.Sleep(1000);
        }
    }
}
