通过FTP上传文件 [英] Uploading Files via FTP

问题描述

大家好！



这是我第一次尝试实现通过FTP上传文件的程序。以下是我到目前为止：

Hi everyone!

This is my first attempt in implementing a procedure to upload files via FTP. Here is what I have so far:

private void ftpOKButton_Click(object sender, EventArgs e)
{
     String sourcefilepath = pathToFileName; 
     String ftpurl = fullFTPHostName;
     String ftpusername = ftpUserNameTextBox.Text.Trim();
     String ftppassword = ftpPasswordTextBox.Text.Trim();

     try
     {
          string filename = Path.GetFileName(sourcefilepath);
          string ftpfullpath = ftpurl;
          FtpWebRequest ftp = (FtpWebRequest)FtpWebRequest.Create(ftpfullpath);
          ftp.Credentials = new NetworkCredential(ftpusername, ftppassword);

          ftp.KeepAlive = true;
          ftp.UseBinary = true;
          ftp.Method = WebRequestMethods.Ftp.UploadFile;

          FileStream fs = File.OpenRead(sourcefilepath);
          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();
     }
     catch (Exception ex)
     {
          MessageBox.Show(ex.Message);
     }
}

我的问题是如何解决我收到的错误：它失败了在这一行：

流ftpstream = ftp.GetRequestStream（）;

，错误消息为：

远程服务器返回错误：（550）文件不可用（例如找不到文件，没有访问权限）。



我已验证该文件位于我尝试访问的路径中。



谢谢大家！

My question is how can I resolve the error I'm receiving: It is failing on this line:
Stream ftpstream = ftp.GetRequestStream();
with the error message of:
"The remote server returned an error: (550) File unavailable (e.g. file not found, no access).

I've verified the file is located in the path that I'm trying to access.

Thanks everyone!

推荐答案

我看不到你在哪里设置ftp。 ContentLength 以告诉服务器需要多少数据。



MSDN FTP上传示例 [ ^ ]有一个工作示例，虽然是文本文件，但是过程s是相同的。

I don't see where you are setting the ftp.ContentLength in order to tell the server how much data to expect.

MSDN FTP Upload Example[^] has a working example, albeit for a text file, but the process is the same.

我使用了太多的主机名，系统不喜欢。我必须在主机名中的文件夹开始之前向上走，并将该部分剪掉。

I used too much of the hostname, which the system didn't like. I had to go up to right before the folders began in the hostname and clip that portion off.
