How to copy a folder and all it's subfolders and files in .NET?

It looks like your code is similar to what is here:

I would recommend you go through that MSDN article and figure out why each piece is doing what it is doing. In the end, you could just copy and paste the code and it would work but it is much better for you if you actually learn why it is doing what it is doing.

You probably are having problems with the path. If you have a slash at the end, then you have a problem. The following seems to work:

private static void CopyDirectory(string sourcePath, string destPath)
{

  if (!Directory.Exists(destPath))
  {
    Directory.CreateDirectory(destPath);
  }
  var fixedSource = new DirectoryInfo(sourcePath);
  var fixedDest = new DirectoryInfo(destPath);

  foreach (var file in fixedSource.GetFiles())
  {
    string dest = Path.Combine(fixedDest.FullName, file.Name);
    file.CopyTo(dest);
  }

  foreach (var folder in fixedSource.GetDirectories())
  {
    string dest = Path.Combine(destPath, folder.Name);
    CopyDirectory(folder.FullName, dest);
  }
}

This is not the way I would recommend that you do it. I would have a non-recursive method that would fix any path issues, then your code will work, but you may have an issue with duplicates, and you need to deal with that also.
