namespace FileExample
{
  class Program
  {
    static void Main(string[] args)
    {

      string fLoc = "Sample";
      DirectoryInfo dir = new DirectoryInfo(fLoc);

      // checking for its existence
      if (dir.Exists)
      {
        Console.WriteLine("The Directory already exists.");
      }
      else
      {
       	// creating directory
        dir.Create();
        Console.WriteLine("Directory Created Successfully!");
      }
    }
  }
}

A directory named “Sample” will be created on a path that you will specify in a program. The program also checks if the directory specified already exists in that path or not.

using System;
using System.IO;

namespace FileExample
{
  class Program
  {
    static void Main(string[] args)
    {
      string fLoc = "sample.text";
      DirectoryInfo dir = new DirectoryInfo(fLoc);

      try
      {
        dir.Delete();
        Console.WriteLine("Directory Deleted Successfully!");
      }

      catch (Exception ex)
      {
        Console.WriteLine("Something is wrong: " + ex.ToString());
      }
    }
