Connect & Copy File from Server DB to local intranet system

I want to connect the server using IP address and port and transfer the Rig Machine data files to my local machine.

It may be intranet based systems or remote systems. Please help me. I just tried this code, but error as

Exception thrown: 'System.Net.Sockets.SocketException' in System.dll.

when it is reaching the line--socket.bind(ipEnd) below:

---------------------------------------------------------------------

{

string host; int port= 5040; host = Convert.ToString("192.162.0.47");

//IPAddress[] IPs = Dns.GetHostAddresses(host);

IPEndPoint ipEnd = new IPEndPoint(IPAddress.Parse(host), 5040);

Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

sock.Bind(ipEnd);

sock.Listen(100);

Socket clientSock = sock.Accept();

byte[] clientData = new byte[1024 * 5000];

string receivedPath = "Projects/";

//Socket clientSock = sock.Accept();

int receivedBytesLen = clientSock.Receive(clientData);

int fileNameLen = BitConverter.ToInt32(clientData, 0);

string fileName = Encoding.ASCII.GetString(clientData, 4, fileNameLen);

Console.WriteLine("Client:{0} connected & File {1} started received.", clientSock.RemoteEndPoint, fileName);

BinaryWriter bWrite = new BinaryWriter(File.Open(receivedPath + fileName, FileMode.Append)); ;

bWrite.Write(clientData, 4 + fileNameLen, receivedBytesLen - 4 - fileNameLen);

Console.WriteLine("File: {0} received & saved at path: {1}", fileName, receivedPath);

bWrite.Close();

clientSock.Close();

Console.ReadLine();

}

Please help me. Thanks a lot.
