C# - How to extract the file name and extension from a path?

Question

So, say I have

string path = "C:\\Program Files\\Program\\File.exe"; 

How do I get only "File.exe"? I was thinking something with split (see below), but what I tried doesn't work...

This is my code.

        List<string> procs = new List<string>(); //Used to check if designated process is already running         foreach (Process prcs in Process.GetProcesses())             procs.Add(prcs.ProcessName); //Add each process to the list         foreach (string l in File.ReadAllLines("MultiStart.txt")) //Get list of processes (full path)             if (!l.StartsWith("//")) //Check if it's commented out                 if (!procs.Contains(l.Split('\\')[l.Split('\\').Length - 1])) //Check if process is already running                     Process.Start(l); 

I'm probably just being a noob. ._.

System.IO has different classes to work with files and directories. Between them, one of the most useful one is Path which has lots of static helper methods for working with files and folders:

Path.GetExtension(yourPath); // returns .exe Path.GetFileNameWithoutExtension(yourPath); // returns File Path.GetFileName(yourPath); // returns File.exe Path.GetDirectoryName(yourPath); // returns C:\Program Files\Program
