如何分别发送数据 [英] How sending data separately

问题描述

大家好
它的问题是，分别发送数据，我将一个整数作为信息从我的传感器发送到服务器程序，我想将另一个整数作为另一个传感器发送到服务器，但是存在一个问题，如何将它们彼此分开，以及我如何理解我在我的服务器程序中得到的内容:
客户端程序:无效发送

hi guys
it`s question about , sending data separately , im send one integer as info form my sensor to server program , i want to send another integer as another sensor to server but there is problem how separate them from each other , and how i can understand which on that i get it in my server program :
client program : Void send

<pre lang="cs">
void sendata(int d)
        {
            byte[] data = new byte[1024];
            data  = BitConverter.GetBytes(d);
            sock.Send(data, data.Length, SocketFlags.None);
        }

然后我将此计时器称为空"，然后将数据发送到服务器:

then i call this void in this timer and send data to server :

<pre lang="cs">
private void timer1_Tick(object sender, EventArgs e)
        {
            try
            {
                sendata(a);
            }
            catch
            {
                //MessageBox.Show("error","er");
                //sock.Shutdown(SocketShutdown.Both);
                //sock.Close();
                //Close();
            }
        }

并在服务器中使用此代码:

and use this code in server :

        private void timer1_Tick(object sender, EventArgs e)
        {
            DateTime startTime = DateTime.Now;
            byte[] data = new byte[1024];
            int recv = client.Receive(data);
            int size = BitConverter.ToInt32(data, 0);
            if (recv != 0)
            {
                label3.Text = " ";
                label3.Text = "co2 ppm is : " + size;
                // label4.Text=""+ siz;
            }
            progressBar1.Maximum = 100;
            progressBar1.Minimum = 0;
            progressBar1.Value = size;
            label2.Text = DateTime.Now.Subtract(startTime).TotalMilliseconds.ToString() + "         :Time To Action" + " ms ";
        }
please tell me how i can send two or more data (int) and get and separate them in server ...

推荐答案

您需要编写应用程序层协议:

You need to write an application layer protocol:

http://en.wikipedia.org/wiki/Application_Layer[^]

Then you need to implement your protocol in both the client and server programs.

I don''t mean to be rude, but if this is for work then you might want to hire someone to help you.
