Networkcomms 是一款C# 語言編寫的TCP/UDP通信框架  作者是英國人  以前是收費的 目前作者已經開源  開源地址是:https://github.com/MarcFletcher/NetworkComms.Net

這一節講一下，如何從伺服器獲取列表數據

示例圖：

客戶單點擊 獲取數據 從伺服器返回數據

客戶端代碼：

  private void button4_Click(object sender, EventArgs e)
        {
            //GetUserList 是數據的請求消息類型
            //ResUserList 是伺服器端返回消息類型 當伺服器返回ResUserList的數據時  客戶端自動對應獲取
            IList<User> listUser = newTcpConnection.SendReceiveObject<string, IList<User>>("GetUserList", "ResUserList", 5000, "100");

            BindData(listUser);
        }

        public void BindData(IList<User> theUsers)
        {
            listView1.Items.Clear();
            listView1.Columns.Clear();
            listView1.View = View.Details;    //新增的 詳細方式
            listView1.AllowColumnReorder = true;
            listView1.FullRowSelect = true;
            listView1.GridLines = true;
          
            listView1.Columns.Add("用戶ID", 100, HorizontalAlignment.Left);
            listView1.Columns.Add("用戶名", 100, HorizontalAlignment.Left);



            foreach (User theUser in theUsers)
            {
                ListViewItem li = new ListViewItem();
                li.SubItems[0].Text = theUser.UserID.ToString();
              
                li.SubItems.Add(theUser.Name);


                listView1.Items.Add(li);

            }
        
        }

伺服器端代碼：

  private void button1_Click(object sender, EventArgs e)
        {
            //IP地址和埠
            IPEndPoint thePoint = new IPEndPoint(IPAddress.Parse(txtIP.Text), int.Parse(txtPort.Text));
            //開始監聽此IP和埠  使用TCP協議
            Connection.StartListening(ConnectionType.TCP, thePoint);

            NetworkComms.AppendGlobalIncomingPacketHandler<string>("GetName", IncomingMsgHandle);

            NetworkComms.AppendGlobalIncomingPacketHandler<User>("UserLong", IncoingHandleLogin);

            NetworkComms.AppendGlobalIncomingPacketHandler<string>("GetUserList", IncoingHandleGetUserList);

            
            button1.Text = "已經開始監聽";
        }

  private void IncoingHandleGetUserList(PacketHeader header, Connection connection, string  param)
        { 
            //模擬一些數據
            IList<User>  userList=new  List<User>();

            User  user1=new User ();
            user1.UserID="10000";
            user1.Name="天涯共此時";

            User  user2=new User();
            user2.UserID="20000";
            user2.Name="海上生明月";

            if (param == "100")
            {
                userList.Add(user1);
                userList.Add(user2);
            }

            else
            {
                userList.Add(user1);
            } 
            connection.SendObject("ResUserList", userList);
        }
