asp.net FileUpload上傳文件夾並檢測所有子文件

<asp:FileUpload ID="FileUpload1" runat="server" webkitdirectory="" />

string DirectoryName = FileUpload1.PostedFile.FileName;
                string path = Server.MapPath("/import/Import_image/" + DirectoryName);
                DirectoryInfo _dicinfo = new DirectoryInfo(path);
                FileInfo[] _files = _dicinfo.GetFiles("*", SearchOption.AllDirectories);
                //以下是處理方法
