如何使用FTP检查目录是否存在?

问题描述：

帮我使用FTP检查目录

Help me to check the directory using FTP

using BytesRoad.Net.Ftp;

FtpClient ftpClient = new FtpClient();
// use passive mode
ftpClient.PassiveMode = true;

int timeout = 0;
// connect to the specified FTP server
ftpClient.Connect(timeout,"URL ", 11 );
ftpClient.Login(timeout,USERNAME,PASSWORD);

rootDirectory = ftpClient.GetWorkingDirectory(timeout);
target = rootDirectory + "/testfolder " ;

我需要检查"target(testfolder)"是否存在
保存测试文档文件之前.
没有像directoryexists这样的扩展名.

I need to check the "target(testfolder)" is exists or not
before saving the test document file.
There is no extensions like directoryexists.

string file_to_save = target + "/test.doc";
// synchronously upload the file
ftpClient.PutFile(0, file_to_save , @"C:\test.doc" );
ftpClient.Disconnect(timeout);

谢谢

如果标准System.Net.FtpWebRequest可以完美地完成工作，为什么还要使用第三方BytesRoad?
如果仍要使用BytesRoad，请询问该库的作者.

我建议您使用标准的System.Net，它是……很好，标准，有据可查，经过测试，可以完美地完成工作.在此处查看您的问题(非常简单)的可能答案之一:

Why would you use third-party BytesRoad if standard System.Net.FtpWebRequest would do the job perfectly?

If you still want to use BytesRoad, ask the author(s) of this library.

I recommend you use standard System.Net which is… well, standard, well documented, tested and perfectly do the job. See one of the possible answers to your (very simple) Question here:
