Send File from Server to Client using C# Socket Programming 6/6

Server codes are here…

 
Server code:
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.Net.Sockets;
using System.IO;
namespace beginSocketServer
{
//FILE TRANSFER USING C#.NET SOCKET – SERVER
class Program
{
static void Main(string[] args)
{
try
{
Console.WriteLine(“That program can transfer small file. I’ve test up to 850kb file”);
IPEndPoint ipEnd = new IPEndPoint(IPAddress.Any, 5656);
Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);
sock.Bind(ipEnd);
sock.Listen(100);
//clientSock is the socket object of client, so we can use it now to transfer data to client
Socket clientSock = sock.Accept();
string fileName = “test.txt”;// “Your File Name”;
string filePath = @”C:\FT\”;//Your File Path;
byte[] fileNameByte = Encoding.ASCII.GetBytes(fileName);
byte[] fileData = File.ReadAllBytes(filePath + fileName);
byte[] clientData = new byte[4 + fileNameByte.Length + fileData.Length];
byte[] fileNameLen = BitConverter.GetBytes(fileNameByte.Length);
fileNameLen.CopyTo(clientData, 0);
fileNameByte.CopyTo(clientData, 4);
fileData.CopyTo(clientData, 4 + fileNameByte.Length);
clientSock.Send(clientData);
Console.WriteLine(“File:{0} has been sent.”, fileName);
clientSock.Close();
Console.ReadLine();
}
catch (Exception ex)
{
Console.WriteLine(“File Receiving fail.” + ex.Message);
}
}
}
