             Console.WriteLine(Path.GetFileNameWithoutExtension(path));
             Console.WriteLine(Path.GetPathRoot(path));
             Console.WriteLine(Environment.SystemDirectory);
         }
     }
 }

result

we usually use codes as below to get current directory:

System.Environment.CurrentDirectory

System.Windows.Forms.Application.StartupPath(using System.Windows.Forms;)

System.IO.Directory.GetCurrentDirectory() (using System.IO;)

I prefer: Enviroment.CurrentDirectory
