检查FTP服务器上是否存在目录

Question

我正在检查我的FTP服务器上是否存在目录:

    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;
    }

在这种情况下:

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

在我的服务器上,我有一个名为的文件夹Rubicon1.这导致我的支票返回true.除非它与目录名称完全匹配,否则如何确保它失败？

我通过将目录更改为以下来成功解决了此问题:

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