问题描述
我想从FTP服务器读取文件而不将其下载到本地文件。我写了一个函数,但它不起作用:
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(ftp_user, ftp_pas);
try
{
byte[] newFileData = request.DownloadData(new Uri(FtpPath)+FileName);
string fileString = System.Text.Encoding.UTF8.GetString(newFileData);
}
catch (WebException e)
{
}
return version;
}
推荐答案
您的代码从Microsoft公共FTP服务器获取文件:
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", "anonymous@example.com");
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.
}
我想你在代码中的这一行缺少一个斜杠:
I reckon you're missing a slash on this line here in your code:
string url = FtpPath + FileName;
也许介于 FtpPath
和 FileName
?
