C# FTP, how to check if a Path is a File or a Directory?

Question

I have an array that contains some FTP pathes, like follows:

"ftp//ip/directory/directory1",
"ftp//ip/directory/directory2",
"ftp//ip/directory/file.txt",
"ftp//ip/directory/directory3",
"ftp//ip/directory/another_file.csv"

How can i find out if the path is a file or a directory?

Thanks in advance.

Answer 1

Use the LIST command, which you can refer to RFC959, to get the details about items under the specified path. Take FileZilla Server for example, the LIST command will return standard LINUX permission format which you can find here. The first letter indicates if the requested path is file or directory. Also a simple library written in C# can be found here

Answer 2

There's no direct way.

Indirectly you could assume that filenames that have no period "." are directories, but that is not going to always be true.

Best is to write the code that consumes these paths carefully so it e.g. treats the path as a directory, then if the FTP server reports an error, treat it as a file.
