    static void Main(string[] args)
    {
        string sourceDirectory = @"C:\source";
        string targetDirectory = @"C:\target";

        CopyDirectory(sourceDirectory, targetDirectory);
    }

    static void CopyDirectory(string sourceDirectory, string targetDirectory)
    {
        // 创建目标目录
        Directory.CreateDirectory(targetDirectory);

        // 获取源目录下的所有文件和子目录
        string[] files = Directory.GetFiles(sourceDirectory);
        string[] directories = Directory.GetDirectories(sourceDirectory);

        // 复制文件
        foreach (string file in files)
        {
            string targetFile = Path.Combine(targetDirectory, Path.GetFileName(file));
            File.Copy(file, targetFile);
        }

        // 复制子目录
        foreach (string directory in directories)
        {
            string targetDirectory = Path.Combine(targetDirectory, Path.GetFileName(directory));
            CopyDirectory(directory, targetDirectory);
