Question

比如说网站是http://localhost/ReceiveFile/DownLoadPhotos.aspx，想要通过winform获取ReceiveFile下的photos文件夹下的所有文件，winform通过uri路径不能访问，那该怎么做啊

Answer 1

ftpwebrequest访问文件夹
文件可通过webclient下载

Answer 2

这是我在服务器端写的代码，从客户端接受文件夹名，然后再返回给客户端这个文件夹下所有文件，这个如何来写啊，下面写的不一定对，不知道怎么才能把文件夹下文件返回给客户端，也不知道如何通过客户端来给服务器端传值，各位高手救救我把
for (int i = 0; i < Request.Files.Count; i++)
        {
            string fileName = Path.GetFileName(Request.Files[i].FileName);
            
            string fileP = Server.MapPath("~/files/");
            string filePath = Server.MapPath("~/files/photos/") + fileName;
            string[] fileNames = Directory.GetFiles(filePath);
            List<string> list = new List<string>();
            foreach (string file in fileNames)
            {
                list.Add(file);
            }
            for (int j = 0; j < list.Count; i++)
            {
                Response.Headers.Add(i.ToString(), list[i]);
            }
            
        }
