Use the System.IO.File and System.IO.Directory classes.
E.g.

C#

string[] files = System.IO.Directory.GetFiles(sourcePath);

// Copy the files and overwrite destination files if they already exist.
foreach (string s in files)
{
    // Use static Path methods to extract only the file name from the path.
    fileName = System.IO.Path.GetFileName(s);
    destFile = System.IO.Path.Combine(targetPath, fileName);
    System.IO.File.Copy(s, destFile, true);
}

C#

private void CopyFolder(string sourcePath, string DestPath, bool overWrite)
{
     DirectoryInfo dir = new DirectoryInfo(sourcePath);

     //iterate through all files
     foreach (FileInfo file in dir.GetFiles())
     {
           file.CopyTo(DestPath  + file.Name, overWrite);
     }
}

Note: Handle some possible errors by own like folder exists, path formats etc.

what about credentials? If user is not allowed on second machine how would you copy then?

It will simply throw exception and that need to be handled.

but no files copied

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

You need to use an Impersonated User. With that impersonated user you acn copy to the second machine

C#

IntPtr admin_token = default(IntPtr);
                        IntPtr dupToken = default(IntPtr);

                        WindowsIdentity wid_current = WindowsIdentity.GetCurrent();
                        WindowsIdentity wid_admin = null;
                        WindowsImpersonationContext wic = null;
                        string[] split = new string[1];
                        split[0] = "\\";
                        string[] temp = ServerName.Split(split, StringSplitOptions.RemoveEmptyEntries);
                        string domain = String.Empty;
                        string userName = ServerUserName;
                        string password = Password;
                        if (LogonUser(userName, domain, password, LOGON32_LOGON_NEW_CREDENTIALS, LOGON32_PROVIDER_DEFAULT, ref admin_token) != 0)
                        {
                            if (DuplicateToken(admin_token, 2, out dupToken))
                            {
                                wid_admin = new WindowsIdentity(dupToken);
                                wic = wid_admin.Impersonate();
                                try
                                {
                                    // File.COPY thing
                                }
                                finally
                                {
                                    if (wic != null)
                                    {
                                        wic.Undo();
                                    }
                                    if (admin_token != default(IntPtr))
                                        CloseHandle(admin_token);

                                    if (dupToken != default(IntPtr))
                                        CloseHandle(dupToken);                             
                                }
                           }
