Best way to copy the entire contents of a directory in C#

I'd like to copy folder with all its subfolders and file from one location to another in .NET. What's the best way to do this?

I see the Copy method on the System.IO.File class, but was wondering whether there was an easier, better, or faster way than to crawl the directory tree.

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);     } }

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.
