如何在 C# 中使用 FTP 列出目录内容?

How to List Directory Contents with FTP in C# ?

我正在使用下面的代码通过 FTP 列出目录内容，它以 XML 格式返回结果，但我只想要目录的名称而不是全部内容.

I am using below code to List Directory Contents with FTP it is returning result in XML format ,but i want only the name of directory not the whole content.

我该怎么做?

public class WebRequestGetExample
{
    public static void Main ()
    {
        // Get the object used to communicate with the server.
        FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://www.contoso.com/");
        request.Method = WebRequestMethods.Ftp.ListDirectoryDetails;

        // This example assumes the FTP site uses anonymous logon.
        request.Credentials = new NetworkCredential ("anonymous","janeDoe@contoso.com");

        FtpWebResponse response = (FtpWebResponse)request.GetResponse();

        Stream responseStream = response.GetResponseStream();
        StreamReader reader = new StreamReader(responseStream);
        Console.WriteLine(reader.ReadToEnd());

        Console.WriteLine("Directory List Complete, status {0}", response.StatusDescription);

        reader.Close();
        response.Close();
    }
}

推荐答案

试试这个:

FtpWebRequest ftpRequest = (FtpWebRequest)WebRequest.Create(uri);
ftpRequest.Credentials =new NetworkCredential("anonymous","janeDoe@contoso.com");
ftpRequest.Method = WebRequestMethods.Ftp.ListDirectory;
FtpWebResponse response = (FtpWebResponse)ftpRequest.GetResponse();
StreamReader streamReader = new StreamReader(response.GetResponseStream());

List<string> directories = new List<string>();

string line = streamReader.ReadLine();
while (!string.IsNullOrEmpty(line))
{
    directories.Add(line);
    line = streamReader.ReadLine();
}

streamReader.Close();

它给了我一个目录列表...全部列在目录字符串列表中...告诉我这是不是你需要的

It gave me a list of directories... all listed in the directories string list... tell me if that is what you needed
