Question

I need to copy many folders from a server to another server. The servers are in different domains. Is tcp or ftp should be used? I am having the login credentials to access the server.
Is it possible to use something like

string sourceFile = @"ServerIP\C:\Users\Public\public\test.txt";
string destinationFile = @"Localhost\C:\Users\Public\private\test.txt";

// To move a file or folder to a new location:
System.IO.File.Copy(sourceFile, destinationFile);

You can grab the idea of doing it using the code snippet below. You can use LogonUser to impersonate a local group also not only domain accounts.

To copy all the contents (files) inside the Directory/Folder, obviously you can use the Directory class from inside System.IO namespace to get all the files information.

Code:

using Microsoft.VisualBasic;
using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Security.Principal;
using System.Security.Permissions;

public class Form1
{
    [DllImport("advapi32.DLL", SetLastError = true)]
    public static extern int LogonUser(string lpszUsername, string lpszDomain, string lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken);
    private void Button1_Click(System.Object sender, System.EventArgs e)
    {
        IntPtr admin_token = default(IntPtr);
        WindowsIdentity wid_current = WindowsIdentity.GetCurrent();
        WindowsIdentity wid_admin = null;
        WindowsImpersonationContext wic = null;
        try {
            MessageBox.Show("Copying file...");
            if (LogonUser("Local Admin name", "Local computer name", "pwd", 9, 0, ref admin_token) != 0) {
                wid_admin = new WindowsIdentity(admin_token);
                wic = wid_admin.Impersonate();
                System.IO.File.Copy("C:\\right.bmp", "\\\\157.60.113.28\\testnew\\right.bmp", true);
                MessageBox.Show("Copy succeeded");
            } else {
                MessageBox.Show("Copy Failed");
            }
        } catch (System.Exception se) {
            int ret = Marshal.GetLastWin32Error();
            MessageBox.Show(ret.ToString(), "Error code: " + ret.ToString());
            MessageBox.Show(se.Message);
        } finally {
            if (wic != null) {
                wic.Undo();
            }
        }
    }
}
