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);

}

}

}
