Tcp File Transfer

[predator5047]

I want to write a Tcp file transfer program , the problem is that when i send the file size and file name the client doesn't receive the as two separate packages but as a package witch contains both the file name , size and the file content.
This is my code:

Socket sk = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            IPEndPoint ipe= new IPEndPoint((Dns.GetHostByName(Dns.GetHostName())).AddressList[0],8000);
        
            sk.Bind(ipe);
            sk.Listen(5);

            Socket sc = sk.Accept();

            FileInfo fi = new FileInfo(line);

            long  size = fi.Length,sent = 0;
            string name = fi.Name;
            System.IO.StreamReader sr = new StreamReader(fi.OpenRead());

            byte[] buffer = new byte[1024];
            char[] char_buffer = new char[1024];

            
            try
            {
                buffer = System.Text.Encoding.ASCII.GetBytes(fi.Name);
                sc.Send(buffer);
                                
                buffer = System.Text.Encoding.ASCII.GetBytes(size.ToString());
                sc.Send(buffer);
            }
            catch(Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
            

            while (sr.EndOfStream != true)
            {
                sr.Read(char_buffer, 0, 1024);
                sent += 1024;

                sc.Send(System.Text.Encoding.ASCII.GetBytes(char_buffer));

                textBox1.Text += "Trimis cu succes ramas:" + (((decimal)sent / size) * 100).ToString() + Environment.NewLine;
            }

            sc.Shutdown(SocketShutdown.Both);
            sk.Shutdown(SocketShutdown.Both);

            sk.Close();
            sr.Close();
            sc.Close();
