I’ll never understand why Microsoft thought a Copy() method for the Directory class wasn’t necessary (but one for the File class was). I love the .NET Framework, but come on, guys! How could this not be important?!

This is just for my reference (or anyone else that needs it). I wrote this little function a while back when I experimented with a few things on the Web site. I needed it again a few days ago when writing an app for work, but I didn’t have it in the office. Being the ever lazy person I am, I’m putting it here so that I can copy and paste it when I need it again:

public static void CopyDirectory(string source, string destination)
{
    string[] files;
    // Make sure the destination ends with ‘\’
    if (destination[destination.Length - 1] != Path.DirectorySeparatorChar) 
        destination += Path.DirectorySeparatorChar;

    if (!Directory.Exists(destination)) 
        Directory.CreateDirectory(destination);

    files = Directory.GetFileSystemEntries(source);
    foreach (string element in files)
    {  
        // Sub-directories
        if (Directory.Exists(element)) 
            CopyDirectory(element,destination + Path.GetFileName(element));
        // Files in current directory
        else 
            File.Copy(element,destination + Path.GetFileName(element),true);
    }
}
