不支持提供的路径格式

Question

我正在尝试通过 FTP

上传文件

The provided format of the path is not supported

代码：

[HttpPost]
    public ActionResult Guardar_registro(Models.CascadingModelLevantamiento model, HttpPostedFileBase file)
    {
      var NombreArchivo = Path.GetFileName(file.FileName);
      string name = Path.Combine("" + NombreArchivo);
      string ftpfullpath = Path.Combine(@"ftp://xxx.xxx.xx.xx:xx" + @"/test/" + name);
      FtpWebRequest ftp = (FtpWebRequest)FtpWebRequest.Create(ftpfullpath);
      ftp.Credentials = new NetworkCredential("xxx@xx.com", "xxx");
      ftp.KeepAlive = true;
      ftp.UseBinary = true;
      ftp.Method = WebRequestMethods.Ftp.UploadFile;
      FileStream fs = System.IO.File.OpenRead(ftpfullpath);
      byte[] buffer = new byte[fs.Length];
      fs.Read(buffer, 0, buffer.Length);
      fs.Close();
      Stream ftpstream = ftp.GetRequestStream();
      ftpstream.Write(buffer, 0, buffer.Length);
      ftpstream.Close();
 }

Answer 1

不要重复发明轮子，尝试这样的事情：

using (var client = new WebClient())
{
    client.Credentials = new NetworkCredential(ftpUsername, ftpPassword);
    client.UploadFile("ftp://host/path.zip", WebRequestMethods.Ftp.UploadFile, localFile);
}

资源link：WebClient

Answer 2

到达 File.OpenRead 的内容必须是有效的本地 (Windows) 路径。不是 FTP URL.

类似于

string filename = System.IO.Path.Combine(@"C:\local\path", NombreArchivo);
FileStream fs = System.IO.File.OpenRead(filename);

虽然在其他答案中评论正确，但更简单的方法是使用 WebClient.UploadFile。
