Path Class in C#

January 14, 2022 C#

In this post, you will learn how to work with the Path class so that you can use that same knowledge and thus evolve.

this class (belonging to the System.IO library) provides various static methods to obtain information about a certain file or directory.

`GetFileName()`	Returns the filename and its extension
`GetFileNameWithoutExtension()`	Returns the filename without the extension
`GetExtension()`	Returns only the file extension
`GetFullPath()`	Returns the entire specified path (absolute path)

when you use const when creating an attribute, you are declaring a constant field which after this declaration cannot be modified.

using System;
using System.IO;

namespace Base {
  class PathClass {
    private const string File = "File.txt";

    public void Run() {
      Console.WriteLine($"File name with extension: {Path.GetFileName(File)}");
      Console.WriteLine($"File name without extension: {Path.GetFileNameWithoutExtension(File)}");
      Console.WriteLine($"File extension: {Path.GetExtension(File)}");
      Console.WriteLine($"Absolute path to file: {Path.GetFullPath(File)}");
    }
  }
}

/*
  File name with extension: File.txt
  File name without extension: File
  File extension: .txt
  Absolute path to file: ...\File.txt
*/
