如何上传具有精确文件夹结构的整个文件夹？

Question

我正在将整个文件夹上传到服务器。
该文件夹中包含文件和子文件夹。
我希望它可以像在本地计算机中一样完全上传。

我尝试了FolderBrowserDialog，然后尝试了文件夹复制逻辑。
它在本地计算机上运行良好，但是在部署之后，我遇到了“未处理的异常”。

上下文：Section1

                    if (fbd.ShowDialog() == DialogResult.OK)
                    {
                        //foreach (var path in Directory.GetFiles(fbd.SelectedPath))
                        //{
