读取FTP文件 [英] read file from ftp

问题描述

我想读从FTP服务器上的文件，而不将其下载到本地文件。我写了一个功能，但它不工作：

 私人字符串GetServerVersion（）
 {
 Web客户端请求=新的Web客户端（）; 
 
字符串URL = FtpPath +文件名; 
字符串版本=; 
 
 request.Credentials =新的NetworkCredential（MailLibConfigurations.ftp_user，MailLibConfigurations.ftp_pas）; 
 
 //request.DownloadFile(new乌里（FtpPath）+文件名，D：\\sdc_version.txt）; 
试
 {
字节[] = newFileData request.DownloadData（新的URI（FtpPath）+文件名）; 
串fileString = System.Text.Encoding.UTF8.GetString（newFileData）; 
} 
赶上（引发WebException五）
 {
} 
返回版本; 
} 
  

解决方案

下面是一个使用简单的工作示例您的代码以抓住从Microsoft公共的FTP服务器的文件：

  Web客户端请求=新的WebClient（）; 
字符串URL =ftp://ftp.microsoft.com/developr/fortran/+README.TXT; 
 request.Credentials =新的NetworkCredential（匿名，[e-mail]）; 
 
试
 {
字节[] = newFileData request.DownloadData（URL）; 
串fileString = System.Text.Encoding.UTF8.GetString（newFileData）; 
 Console.WriteLine（fileString）; 
} 
赶上（引发WebException五）
 {
 //做一些诸如日志错误，但是这是基于OP原代码
 //所以现在我们没做什么。 
} 
  

我觉得你在你的代码在这里失去了在这条线斜线：

 字符串的URL = FtpPath +文件名; 
  

也许 FtpPath 和<$ C $之间C>文件名？

I want to read a file from a FTP server without downloading it to a local file. I wrote a function but it does not work:

private string GetServerVersion()
{
    WebClient request = new WebClient();

    string url = FtpPath + FileName;
    string version = "";

    request.Credentials = new NetworkCredential(MailLibConfigurations.ftp_user, MailLibConfigurations.ftp_pas);

    //request.DownloadFile(new Uri(FtpPath) + FileName, "D:\\sdc_version.txt");
    try
    {
        byte[] newFileData = request.DownloadData(new Uri(FtpPath)+FileName);
        string fileString = System.Text.Encoding.UTF8.GetString(newFileData);
    }
    catch (WebException e)
    {
    }
    return version;
}

解决方案

Here's a simple working example using your code to grab a file from the Microsoft public FTP servers:

WebClient request = new WebClient();
string url = "ftp://ftp.microsoft.com/developr/fortran/" +"README.TXT";
request.Credentials = new NetworkCredential("anonymous", "[e-mail]");

try
{
  byte[] newFileData = request.DownloadData(url);
  string fileString = System.Text.Encoding.UTF8.GetString(newFileData);
  Console.WriteLine(fileString);
}
catch (WebException e)
{
  // Do something such as log error, but this is based on OP's original code
  // so for now we do nothing.
}

I reckon you're missing a slash on this line here in your code:

string url = FtpPath + FileName;

Perhaps between FtpPath and FileName ?
