C# program to create a directory

using System;
using System.IO;

namespace ConsoleApplication1 {
  class Program {
    static void Main() {
      Console.WriteLine("Directory creating:");

      Directory.CreateDirectory("D:/India");
      Console.WriteLine("D:/India");

      Directory.CreateDirectory("D:/India/NCR");
      Console.WriteLine("D:/India/NCR");

      Directory.CreateDirectory("D:/India/NCR/DELHI");
      Console.WriteLine("D:/India/NCR/DELHI");

      Directory.CreateDirectory("D:/India/NCR/NOIDA");
      Console.WriteLine("D:/India/NCR/NOIDA");

      Directory.CreateDirectory("D:/India/NCR/GURUGRAM");
      Console.WriteLine("D:/India/NCR/GURUGRAM");
    }
  }
}
