Get directory name from full directory path regardless of trailing slash

Question

I need to get the directory name from its path regardless of any of having a trailing backslash. For example, user may input one of the following 2 strings and I need the name of logs directory:

"C:\Program Files (x86)\My Program\Logs"
"C:\Program Files (x86)\My Program\Logs\"

None of the following gives correct answer ("Logs"):

Path.GetDirectoryName(m_logsDir);
FileInfo(m_logsDir).Directory.Name;

They apparently analyze the path string and in the 1st example decide that Logs is a file while it's really a directory.

So it should check if the last word (Logs in our case) is really a directory; if yes, return it, if no (Logs might be a file too), return a parent directory. If would require dealing with the actual filesystem rather than analyzing the string itself.

Is there any standard function to do that?

Answer 1

new DirectoryInfo(m_logsDir).Name;

Answer 2

This may help

var result = System.IO.Directory.Exists(m_logsDir) ? 
              m_logsDir: 
              System.IO.Path.GetDirectoryName(m_logsDir);
