C# / .NET - create directory with subdirectory

In this article, we would like to show you how to create directory in C#.

Quick solution:

string path = @"C:\path\directory\subdirectory1\subdirectory2"

if (!Directory.Exists(path))
{
    Directory.CreateDirectory(path);
}

directory/
  |
  +-- subirectory1/
          |
          +-- subdirectory2/

Practical example

In this example, we use CreateDirectory() method to create directory with subdirectories if it doesn't exist.

using System;
using System.IO;

public static class Program
{
    public static void Main(string[] args)
    {
        string path = @"C:\path\directory\subdirectory1\subdirectory2";

        try
        {
            // Check if the directory exists
            if (Directory.Exists(path))
            {
                Console.WriteLine("That path already exists.");
                return;
            }

            // Create directory
            DirectoryInfo dir = Directory.CreateDirectory(path);
            Console.WriteLine("The directory was created successfully.");
        }
        catch (Exception e)
        {
            Console.WriteLine("The process failed: {0}", e.ToString());
        }
    }
}
