Here是如何做到的:

private static void DirectoryCopy(string sourceDirName, string destDirName, bool copySubDirs)
{
    DirectoryInfo dir = new DirectoryInfo(sourceDirName);
    DirectoryInfo[] dirs = dir.GetDirectories();

    if (!dir.Exists)
    {
        throw new DirectoryNotFoundException(
            "Source directory does not exist or could not be found: "
            + sourceDirName);
    }

    if (!Directory.Exists(destDirName))
    {
        Directory.CreateDirectory(destDirName);
    }

    FileInfo[] files = dir.GetFiles();
    foreach (FileInfo file in files)
    {
        string temppath = Path.Combine(destDirName, file.Name);
        file.CopyTo(temppath, false);
    }

    if (copySubDirs)
    {
        foreach (DirectoryInfo subdir in dirs)
        {
            string temppath = Path.Combine(destDirName, subdir.Name);
            DirectoryCopy(subdir.FullName, temppath, copySubDirs);
        }
    }
}
