C# / .NET - create directory

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

Quick solution:

string path = @"C:\path\to\directory";

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

Warning: the above source code may thrown some exceptions, so it is good to catch or forward them.

Practical example

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

using System;
using System.IO;

public static class Program
{
    public static void Main(string[] args)
    {
        string path = @"C:\Users\Username\Desktop\example\dir1";

        try
        {   
            if (Directory.Exists(path)) // checks if the directory exists
                Console.WriteLine("That directory already exists.");
            
            else
            {
                DirectoryInfo directory= Directory.CreateDirectory(path); // creates a directory

                Console.WriteLine("The directory was created successfully.");
            }
        }
        catch (Exception e)
        {
            Console.WriteLine("The operation failed: {0}", e.ToString());
        }
    }
}

Result:
