<p>Does anyone know how I can add a class to the link rendered using the Html.RouteLink helper method in ASP.Net MVC, it has the htmlAttributes object as the last parameter which I assumed I would be able to use, but since class is obviously a reserved word, I cannot supply this as one of the properties on the object.</p>

Just use uppercase for html attribute, like this:
```
```
<%= Html.RouteLink("Default", "Default",null, new { Class="css_class"}) %>
```
```
