Answer 2

A simple function that copies the entire contents of the source folder to the destination folder and creates the destination folder if it doesn't exist

class Utils
{
    internal static void copy_dir(string source, string dest)
    {
        if (String.IsNullOrEmpty(source) || String.IsNullOrEmpty(dest)) return;
        Directory.CreateDirectory(dest);
        foreach (string fn in Directory.GetFiles(source))
        {
            File.Copy(fn, Path.Combine(dest, Path.GetFileName(fn)), true);
        }
        foreach (string dir_fn in Directory.GetDirectories(source))
        {
            copy_dir(dir_fn, Path.Combine(dest, Path.GetFileName(dir_fn)));
        }
    }
}

This link provides a nice example.

Here is a snippet

// To copy all the files in one directory to another directory.
// Get the files in the source folder. (To recursively iterate through
// all subfolders under the current directory, see
// "How to: Iterate Through a Directory Tree.")
// Note: Check for target path was performed previously
//       in this code example.
if (System.IO.Directory.Exists(sourcePath))
{
  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);
  }
}
