How to copy files from one folder to another folder

DirectoryInfo src = new DirectoryInfo(@"E:\Test\Dir1");
DirectoryInfo dest = new DirectoryInfo(@"C:\Dir2");
CopyDirectory(src, dest);


static void CopyDirectory(DirectoryInfo source, DirectoryInfo destination)
{
            if (!destination.Exists)
            {
                destination.Create();
            }

            // Copy all files.
            FileInfo[] files = source.GetFiles();
            foreach (FileInfo file in files)
            {
                file.CopyTo(Path.Combine(destination.FullName,
                    file.Name));
            }

            // Process subdirectories.
            DirectoryInfo[] dirs = source.GetDirectories();
            foreach (DirectoryInfo dir in dirs)
            {
                // Get destination directory.
                string destinationDir = Path.Combine(destination.FullName, dir.Name);

                // Call CopyDirectory() recursively.
                CopyDirectory(dir, new DirectoryInfo(destinationDir));
            }
}
