Read only attribute

How do you programatically remove the "read-only" attribute from a file in a certain directory. I know in VB - I used a shell command in VB - but I suppose there is a more elegant way in C#.

Code:

using System;
using System.IO;
using System.Text;

class FileAttributesExample 
{
    public static void Main() 
    {   
           // Remove read only attribute
            string filepath = @"c:\temp\Readonly.txt";
            File.SetAttributes(filepath, FileAttributes.Archive);
    }
}
