Example

The following C# code example demonstrates how to create a directory, create a file inside it, and then delete the directory.

using System;
using System.IO;

public class DirectoryExample
{
    public static void Main(string[] args)
    {
        string dirPath = @"C:\MyTestDirectory";
        string filePath = Path.Combine(dirPath, "MyTestFile.txt");

        try
        {
            // Create the directory
            Directory.CreateDirectory(dirPath);
            Console.WriteLine($"Directory '{dirPath}' created successfully.");

            // Create a file inside the directory
            File.WriteAllText(filePath, "This is a test file.");
            Console.WriteLine($"File '{filePath}' created successfully.");

            // List all files in the directory
            string[] files = Directory.GetFiles(dirPath);
            Console.WriteLine($"Files in '{dirPath}':");
            foreach (string file in files)
            {
                Console.WriteLine($"- {file}");
            }

            // Delete the file and then the directory
            File.Delete(filePath);
            Console.WriteLine($"File '{filePath}' deleted.");

            Directory.Delete(dirPath);
            Console.WriteLine($"Directory '{dirPath}' deleted.");
        }
        catch (IOException e)
        {
            Console.WriteLine($"An error occurred: {e.Message}");
        }
    }
}
