I recently faced the problem of being unable to copy a directory recursively in C-Sharp. I therefore searched around the internet and found a pretty neat solution on the web. In order to copy a directory recursively, all you have to do is write a recursive function copying all files inside the folder which calls itself whenever a sub-directory is about to be copied. The following example code demonstrates how to copy a directory recursively.

private void CopyFolderRecursively(string sourceFolder, string destFolder)
{
    if (!System.IO.Directory.Exists(destFolder))
        System.IO.Directory.CreateDirectory(destFolder);
    string[] files = System.IO.Directory.GetFiles(sourceFolder);
    foreach (string file in files)
    {
        string name = System.IO.Path.GetFileName(file);
        string dest = System.IO.Path.Combine(destFolder, name);
        System.IO.File.Copy(file, dest);
    }
    string[] folders = System.IO.Directory.GetDirectories(sourceFolder);
    foreach (string folder in folders)
    {
        string name = System.IO.Path.GetFileName(folder);
        string dest = System.IO.Path.Combine(destFolder, name);
        CopyFolderRecursively(folder, dest);
    }
}
