ASP.NET C# Copy Directory with SubDirectories with System.IO

Question

I need to copy a whole directory C:\\X to C:\\Y\\X, and I need the sub-folders to be copied as well.
Is there any way to do it with the System.IO.File\\Directory namespa

This is copied from xneurons blog.

public static void CopyAll(DirectoryInfo source, DirectoryInfo target) {
    // Check if the target directory exists, if not, create it.
    if (Directory.Exists(target.FullName) == false) {
        Directory.CreateDirectory(target.FullName);
    }

    // Copy each file into it’s new directory.
    foreach (FileInfo fi in source.GetFiles()) {
        Console.WriteLine(@"Copying {0}\{1}", target.FullName, fi.Name);
        fi.CopyTo(Path.Combine(target.ToString(), fi.Name), true);
    }

    // Copy each subdirectory using recursion.
    foreach (DirectoryInfo diSourceSubDir in source.GetDirectories()) {
        DirectoryInfo nextTargetSubDir =
            target.CreateSubdirectory(diSourceSubDir.Name);
        CopyAll(diSourceSubDir, nextTargetSubDir);
    }
}
