如何在C#中订购在创建日期之前从FTP收到的文件

我收到一个FTP目录中的文件名列表。但现在文件名是按文件名排序的。我想要的是在将文件保存到列表中之前，按创建日期对其进行排序。我就是不知道怎么做

以下是我如何接收文件名并将它们添加到字符串列表中。

try
        {
            FtpWebRequest request = (FtpWebRequest)WebRequest.Create(URI);
            request.Method = WebRequestMethods.Ftp.ListDirectory;
            request.Credentials = new NetworkCredential(ftpUsername, ftpPassword);
            FtpWebResponse response = (FtpWebResponse)request.GetResponse();
            Stream responseStream = response.GetResponseStream();
            StreamReader reader = new StreamReader(responseStream);
            string names = reader.ReadToEnd();
            reader.Close();
            response.Close();
            return names.Split(new string[] { "'r'n" }, StringSplitOptions.RemoveEmptyEntries).ToList();
        }
        catch (Exception)
        {
            throw;
        }

编辑：

所以我发现我以前接收文件的方式没有包含文件创建时间的详细信息，所以我需要用另一种方式获取文件，以便获得创建日期。
这是我获取文件的新方法。

try
        {
            /* Create an FTP Request */
            ftpRequest = (FtpWebRequest)FtpWebRequest.Create(URI);
            /* Log in to the FTP Server with the User Name and Password Provided */
            ftpRequest.Credentials = new NetworkCredential(ftpUsername, ftpPassword);
            /* When in doubt, use these options */
            ftpRequest.UseBinary = true;
            ftpRequest.UsePassive = true;
            ftpRequest.KeepAlive = true;
            /* Specify the Type of FTP Request */
            ftpRequest.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
            /* Establish Return Communication with the FTP Server */
            ftpResponse = (FtpWebResponse)ftpRequest.GetResponse();
            /* Establish Return Communication with the FTP Server */
            ftpStream = ftpResponse.GetResponseStream();
            /* Get the FTP Server's Response Stream */
            StreamReader ftpReader = new StreamReader(ftpStream);
            /* Store the Raw Response */
            string directoryRaw = null;
            /* Read Each Line of the Response and Append a Pipe to Each Line for Easy Parsing */
            try
            {
                while (ftpReader.Peek() != -1) 
                { 
                    directoryRaw += ftpReader.ReadLine() + "|"; 
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }
            /* Resource Cleanup */
            ftpReader.Close();
            ftpStream.Close();
            ftpResponse.Close();
            ftpRequest = null;
            /* Return the Directory Listing as a string Array by Parsing 'directoryRaw' with the Delimiter you Append (I use | in This Example) */
            try
            {
                string[] directoryList = directoryRaw.Split("|".ToCharArray()); 
                return directoryList;
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.ToString());
        }
        /* Return an Empty string Array if an Exception Occurs */
        return new string[] { "" };

但我仍然不太清楚如何在创建日期后对文件进行排序。有没有一种方法可以编写某种类型的linq查询，比如Orderby？

Array.Sort(arrayOfFiles)

try
        {
            /* Create an FTP Request */
            ftpRequest = (FtpWebRequest)FtpWebRequest.Create(URI);
            /* Log in to the FTP Server with the User Name and Password Provided */
            ftpRequest.Credentials = new NetworkCredential(ftpUsername, ftpPassword);
            /* When in doubt, use these options */
            ftpRequest.UseBinary = true;
            ftpRequest.UsePassive = true;
            ftpRequest.KeepAlive = true;
            /* Specify the Type of FTP Request */
            ftpRequest.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
            /* Establish Return Communication with the FTP Server */
            ftpResponse = (FtpWebResponse)ftpRequest.GetResponse();
            /* Establish Return Communication with the FTP Server */
            ftpStream = ftpResponse.GetResponseStream();
            /* Get the FTP Server's Response Stream */
            StreamReader ftpReader = new StreamReader(ftpStream);
            /* Store the Raw Response */
            string directoryRaw = null;
            /* Read Each Line of the Response and Append a Pipe to Each Line for Easy Parsing */
            try
            {
                while (ftpReader.Peek() != -1) 
                { 
                    directoryRaw += ftpReader.ReadLine() + "|"; 
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }
            /* Resource Cleanup */
            ftpReader.Close();
            ftpStream.Close();
            ftpResponse.Close();
            ftpRequest = null;
            /* Return the Directory Listing as a string Array by Parsing 'directoryRaw' with the Delimiter you Append (I use | in This Example) */
            try
            {
                string[] directoryList = directoryRaw.Split("|".ToCharArray());
                Array.Sort(directoryList);
                return directoryList;
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.ToString());
        }
        /* Return an Empty string Array if an Exception Occurs */
        return new string[] { "" };

 string[] fileNames = Directory.GetFiles("directory ", "*.*");
 DateTime[] creationTimes = new DateTime[fileNames.Length];
 for (int i = 0; i < fileNames.Length; i++)
 creationTimes[i] = new FileInfo(fileNames[i]).CreationTime;
 Array.Sort(creationTimes, fileNames);
