How do I copy a folder and all subfolders and files in .NET? [duplicate]

Answer 1

Well, there's the VisualBasic.dll implementation that Steve references, and here's something that I've used.

private static void CopyDirectory(string sourcePath, string destPath)
{
    if (!Directory.Exists(destPath))
    {
        Directory.CreateDirectory(destPath);
    }

    foreach (string file in Directory.GetFiles(sourcePath))
    {
        string dest = Path.Combine(destPath, Path.GetFileName(file));
        File.Copy(file, dest);
    }

    foreach (string folder in Directory.GetDirectories(sourcePath))
    {
        string dest = Path.Combine(destPath, Path.GetFileName(folder));
        CopyDirectory(folder, dest);
    }
}

If you don't get anything better... perhaps use Process.Start to fire up robocopy.exe?

Michal Talaga references the following in his post:

• Microsoft's explanation about why there shouldn't be a Directory.Copy() operation in .NET.
• An implementation of CopyDirectory() from the Microsoft.VisualBasic.dll assembly.

However, a recursive implementation based on File.Copy() and Directory.CreateDirectory() should suffice for the most basic of needs.
