检查FTP服务器上是否存在目录 [英] Check if directory exists on FTP server

问题描述

  public bool DirectoryExists（字符串目录）
 {
 bool directoryExists; 
 
 var request =（FtpWebRequest）WebRequest.Create（directory）; 
 request.Method = WebRequestMethods.Ftp.ListDirectory; 
 request.Credentials = new NetworkCredential（user，pass）; 
 
尝试
 {
 using（request.GetResponse（））
 {
 directoryExists = true; 
} 
} 
 catch（WebException）
 {
 directoryExists = false; 
} 
 
 return directoryExists; 
 
 $ / code> 

在这种情况下：



  directory = @ftp://ftp.example.com/Rubicon; 
  

在我的服务器上，我有一个名为 Rubicon1 。这导致我的检查返回 true 。我如何确保它失败，除非它完全匹配目录名称？

解决方案

通过更改我的目录，我成功地解决了这个问题：

  directory = @ftp://ftp.example.com/Rubicon/; 
  

I'm running a check to see if a directory exists on my FTP server:

    public bool DirectoryExists(string directory)
    {
        bool directoryExists;

        var request = (FtpWebRequest)WebRequest.Create(directory);
        request.Method = WebRequestMethods.Ftp.ListDirectory;
        request.Credentials = new NetworkCredential("user", "pass");

        try
        {
            using (request.GetResponse())
            {
                directoryExists = true;
            }
        }
        catch (WebException)
        {
            directoryExists = false;
        }

        return directoryExists;
    }

In this case:

directory = @"ftp://ftp.example.com/Rubicon";

On my server, I have a folder named Rubicon1. This is causing my check to return true. How can I ensure that it fails unless it matches the directory name exactly?

解决方案

I successfully solved this issue by changing my directory to be:

directory = @"ftp://ftp.example.com/Rubicon/";
