Is there a better way of doing this... 

```
MyString.Trim().Replace("&", "and").Replace(",", "").Replace("  ", " ")
         .Replace(" ", "-").Replace("'", "").Replace("/", "").ToLower();

```

I've extended the string class to keep it down to one job but is there a quicker way?

```
public static class StringExtension
{
    public static string clean(this string s)
    {
        return s.Replace("&", "and").Replace(",", "").Replace("  ", " ")
                .Replace(" ", "-").Replace("'", "").Replace(".", "")
                .Replace("eacute;", "é").ToLower();
    }
}

```

Just for fun (and to stop the arguments in the comments)
I've shoved a gist up benchmarking the various examples below.

The regex option scores terribly; the dictionary option comes up the fastest; the long winded version of the stringbuilder replace is slightly faster than the short hand.
