Answer 1

My version of DirectoryInfo.CopyTo using extension.

public static class DirectoryInfoEx {
    public static void CopyTo(this DirectoryInfo source, DirectoryInfo target) {
        if (source.FullName.ToLower() == target.FullName.ToLower())
            return;

        if (!target.Exists)
            target.Create();

        foreach (FileInfo f in source.GetFiles()) {
            FileInfo newFile = new FileInfo(Path.Combine(target.FullName, f.Name));
            f.CopyTo(newFile.FullName, true);
        }

        foreach (DirectoryInfo diSourceSubDir in source.GetDirectories()) {
            DirectoryInfo nextTargetSubDir = target.CreateSubdirectory(diSourceSubDir.Name);
            diSourceSubDir.CopyTo(nextTargetSubDir);
        }
    }
}

And use like that...

DirectoryInfo d = new DirectoryInfo("C:\Docs");
d.CopyTo(new DirectoryInfo("C:\New"));
