Q:

Copy all files from a directory without creating subdirectories

I am trying to take a directory and create a new directory in TEMP, that contains all the files in the original directory, but not create additional sub-directories.
Here is what I have so far:
Directory.CreateDirectory(Path.Combine(Path.GetTempPath() + "C# Temporary Files"));
            string lastFolder = new DirectoryInfo(folders.SelectedPath).Name;

foreach (string newPath in Directory.GetFiles(folders.SelectedPath, "*.*",SearchOption.AllDirectories)
                    .Where(s=>s.EndsWith(".c")|| s.EndsWith(".h")))
                {
                    File.Copy(newPath, newPath.Replace(folders.SelectedPath, Path.GetTempPath() + "C# Temporary Files\\" + GlobalVar.GlobalInt));
                }

This works in copying files that are in the directory itself, but not files in subdirectories.  Instead it throws the error: 

System.IO.DirectoryNotFoundException.

An example of the error: 

Could not find a part of the path
  'C:\Users\username\AppData\Local\Temp\C# Temporary Files\outer
  directory\sub-directory\filename'.

A:

I'd it recursively - maybe something like the below sudo code... not tested..
public void CopyRecursive(string path, string newLocation)
{
    foreach(var file in DirectoryInfo.GetFiles(path))
    {
        File.Copy(file.FullName, newLocation + file.Name);
    }

    foreach(var dir in DirectoryInfo.GetDirectories(path))
    {
        CopyRecursive(path + dir.Name, newLocation);
    }
}
