To copy all files from one directory to another while **preserving the directory structure**, you can use a recursive approach that walks through each subdirectory and recreates the same structure in the destination.

Here’s a complete example in C#:

### Recursive Directory Copy (Preserving Structure)

```cs
using System;
using System.IO;

public class DirectoryCopier
{
    public static void CopyDirectory(string sourceDir, string destDir)
    {
        // Create the destination directory if it doesn't exist
        Directory.CreateDirectory(destDir);

        // Copy all files in the current directory
        foreach (var filePath in Directory.GetFiles(sourceDir))
        {
            string fileName = Path.GetFileName(filePath);
            string destFilePath = Path.Combine(destDir, fileName);
            File.Copy(filePath, destFilePath, overwrite: true);
        }

        // Recurse into subdirectories
        foreach (var subDir in Directory.GetDirectories(sourceDir))
        {
            string subDirName = Path.GetFileName(subDir);
            string newDestSubDir = Path.Combine(destDir, subDirName);
            CopyDirectory(subDir, newDestSubDir);
        }
    }
}
```

### Example Usage

```cs
string source = @"C:\SourceFolder";
string destination = @"D:\BackupFolder";

DirectoryCopier.CopyDirectory(source, destination);
```

### Notes

- This method recreates the exact folder and file hierarchy from the source in the destination.
- Files are overwritten if they already exist in the destination (`overwrite: true`).
- It works for both small and large directory trees.
