i need to develop a Windows service which will copy a file in its home system to another system inside a network

below is the code to read the file in the home system

C#

string ipAddress = "192.168.1.15";
           //int port = int.Parse(txtHost.Text);
           //string fileName = "Alert.wav";

           if (!string.IsNullOrEmpty(ipAddress))
           {
               byte[] fileNameByte = Encoding.ASCII.GetBytes(fileName);
               byte[] fileData = File.ReadAllBytes(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);
               TcpClient clientSocket = new TcpClient(ipAddress,53);
               NetworkStream networkStream = clientSocket.GetStream();
               networkStream.Write(clientData, 0, clientData.GetLength(0));
               networkStream.Close();
           }

i need to take these copied / written bytes & then write these in another computer inside a network

C#

File.Copy(@"\\server\sourceFileFolder\file1", @"\\server2\destinationFileFolder\file1");

You need a permission to copy file. if error comes try this impersonation.

C#

AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);

WindowsIdentity idnt = new WindowsIdentity(username, password);

WindowsImpersonationContext context = idnt.Impersonate();

File.Copy("Location1", "Location2"), true);

context.Undo();

or

C#

using ( new Impersonator( "myUsername", "myDomainname", "myPassword" ) )
{
   // code that executes under the new context.
   File.Copy( x, y );
}
