How to create multiple directories from a single full path in C#?

Create directories from complete filepath

private String EvaluatePath(String path){

    try
    {
        String folder = Path.GetDirectoryName(path);
        if (!Directory.Exists(folder))
        {
            // Try to create the directory.
            DirectoryInfo di = Directory.CreateDirectory(folder);
        }
    }
    catch (IOException ioex)
    {
        Console.WriteLine(ioex.Message);
        return "";
    }
    return path;
}

I would call Directory.CreateDirectory(@"C:\dir0\dir1\dir2\dir3\dir4\").

Contrary to popular belief, Directory.CreateDirectory will automatically create whichever parent directories do not exist.
In MSDN's words, Creates all directories and subdirectories as specified by path.

If the entire path already exists, it will do nothing. (It won't throw an exception)
