# How do you create a nested directory structure in one line?

You can create a **nested directory structure in one line** in C# using:

```cs
Directory.CreateDirectory(@"C:\MainFolder\SubFolder1\SubFolder2");
```

### How it works:

1. If any intermediate directories (like `MainFolder` or `SubFolder1`) **don’t exist**, they are automatically created.
2. If the directory **already exists**, no error is thrown — it's safe to call repeatedly.

### Example:

```cs
using System.IO;

class Program
{
    static void Main()
    {
        Directory.CreateDirectory(@"C:\Logs\2025\May\08");
    }
}
```

This creates all folders (`Logs`, `2025`, `May`, `08`) if they don't exist.
